2018’s Best Home Water Purification System Reviews

    Shares

    Water purification systems come in all forms and sizes. Each type has its own pros and cons:

    • Some have a higher initial price tag, but are more cost effective in the long run.
    • Others are portable, but at the same time limited in their water storage volume.
    • Yet others are easy to install and use, but mainly improve water aesthetics and barely touch the more stubborn and more harmful contaminants, such as lead and chlorination byproducts.

    The point is, although every water purifier will give you the benefit of having access to water that is more tasty and somewhat cleaner and safer than it was before, choosing one that is perfectly suited to your needs requires careful consideration.

    But don’t worry, we will help you make the right buying decision. Let’s find you the best water purifier!

    What You Need to Consider

    Before you go out and spend your hard-earned money on a random water purifier, make sure to read through this quick checklist of what you need to consider to protect yourself from disappointment.

    1. Contaminants – Have you tested your water? If not, it’s definitely a good idea to do so. This way you know with certainty what contaminants you are facing and can choose the right purification system accordingly.
    2. NSF standards – Manufacturers and dealers can make claims about contaminant reduction rates all day long. Only certifications according to NSF standards can give you the peace of mind that these claims are indeed true.
    3. Costs – Especially pitchers and faucet water filters are inexpensive to purchase. However, due to low filtration capacities, their total annual filter replacement costs can be many times higher than you think. Under sink or whole house systems on the other hand come with larger cartridges that last 1, 2 or even up to 5 years, so you have to spend less on replacement parts.
    4. Installation – For some purifiers to work, they require you to make permanent changes to the plumbing system, which is a no-go for renters. Also, if you are not handy around the house, you might have to pay a professional plumber to do the installation for you.
    5. Maintenance – We already mentioned that larger filters require less frequent replacements, which can be a real time saver. Some water purifiers don’t require any maintenance at all, which is even better. For multi-stage systems, we always prefer a modular filter design. It simplifies the cleaning.
    6. Flow rate – A high flow rate avoids long waiting times. This is all the more important for whole families.
    7. Storage volume – If a purifier’s flow rate is low, at least make sure that it has a large enough storage volume – unless you are single. In this case it doesn’t really matter.
    8. Size – Under the sink, in the basement, on the kitchen counter. You have to have enough space to accommodate a purification system.

    •    Flow Rate: 3-8 gpm
    •    NSF Standard: 42, 372
    •    Annual Costs: ~$120.00

    Whole house purification systems, or point-of-entry (POE) systems, treat all the incoming water to your home. They usually use a mix of sediment, carbon and sometimes specialized iron, lead or manganese filter cartridges to

    • improve water aesthetics,
    • reduce heavy metal content and to some extent hardness,
    • and eliminate as many other potential contaminants as possible to make the water safe(r) to drink.

    Especially if you are on a well, this will not only help to protect your household appliances from clogging, there will also be less stains on your kitchen and bathroom surfaces and fittings. As an added benefit, you get softer laundry plus healthier looking hair and skin.

    Pros

    • Convenient to use
    • Cost effective
    • Filtered water everywhere in your home
    • Your skin absorbs less chemicals while showering and bathing
    • Cleaner clothes
    • Increase lifespan of water-using appliances and plumbing system
    • Reduce formation of soap scum
    • Cleaner air inside your home

    Cons

    • Higher initial investment
    • Do not remove smaller impurities
    • More likely to require installation by a professional
    • Higher maintenance requirements

    iSpring WGB32B Review

    iSpring WGB32B

    #1 Whole House Purification System: iSpring WGB32B

    •    Price: $$$$
    •    Micron: 5
    •    Flow Rate: 15 gpm
    •    NSF Standard: 42, 53
    •    Annual Costs: ~$230.00

    What We Like

    The first whole house water purification system that we like to recommend is the iSpring WGB32B 3-Stage. It’s a very popular model and best suited if your are on city water with excessive levels of chlorine and some hardness minerals.

    iSpring also offers specialized iron, manganese and lead removal filters for well water treatment.

    As for the iSpring WGB32B 3-Stage, the benefits you get are better tasting water, softer laundry and smoother skin and hair.

    NSF certifications guarantee at least 95% chlorine removal and the reduction of pesticides, herbicides, cryptosporidium, giardia and lead among other harmful stuff.

    The flow rate is 15 gpm which is sufficient for families of 4 to 6 people. Filtering capacity? About 100,000 gallons – enough for 6 to 12 months depending on your water usage.

    By the way, replacement filters are affordable and you can buy them in bulk to make extra savings.

    Furthermore, you don’t need to be a licensed plumber to be able to install this beauty, but don’t underestimate it either. It’s not going to be a piece of cake.

    The good news is that iSpring’s customer support is very helpful and response time is quick. So don’t hesitate to reach out if you get stuck.

    What We Don’t Like

    We have one minor issue:

    The filter cartridges and their housings are heavy, so you might need a helping hand for the annual/biannual filter replacements.

    Our Verdict

    Based on our reviews, the iSpring WGB32B 3-Stage is our top choice when it comes to whole house city water purifiers. It’s reasonably priced, has received a lot of positive feedback, and in case you have special requirements, you can simply opt for one of the filter variants that are part of the series.

    Other Whole House Purifiers

    Culligan WH-HD200-C

    The Culligan WH-HD200-C is a best seller on Amazon mostly because it comes at a fraction of the cost of what you pay for competitor models.

    The downside is that the single-stage unit is mainly used to protect your water-using appliances and plumbing system from sediment and scale. Yes, it will also improve how your water looks, tastes and smells, but there is no guarantee for food grade purity.

    Depending on your preferences, you can choose from 5 different and inexpensive filter cartridges all with varying capacities (10,000 – 24,000 gallons) and micron ratings (5 – 50). The replacement itself can get a little messy.

    Best Water Purification System for Wells: Home Master HMF3SDGFEC

    Home Master HMF3SDGFEC

    #1 Well Water Purifier: Home Master HMF3SDGFEC

    •    Price: $$$$
    •    Micron: 1
    •    Flow Rate: 15 gpm
    •    NSF Standard:
    •    Annual Costs: ~$300.00

    What makes the Home Master HMF3SDGFEC whole house well water purifier stand out is the fact that it provides a high enough flow rate for larger households while still removing contaminants down to 1 micron in size.

    The system can handle iron, manganese, lead, mercury, sulfur, VOCs and other chemicals – especially those from agricultural runoff – but is not recommended for chlorinated waters.

    Maintenance requirements are low, which is convenient and will save you time and money.

    Plus you can save even more by switching to third-party replacement filters. Home Master’s OEM filters are relatively expensive.

    Last but not least, everything is backed by a 2-year limited warranty and a professional customer support team.

    Reverse osmosis is the most commonly applied method for the purification of drinking water. It also provides the most thorough filtration of all residential water treatment technologies.

    The semipermeable membrane at the heart of an RO system rejects between 95 and 99 percent of all contaminants down to 0.0001 microns. This is the reason why RO water is used in medical applications and other industry processes that require exceptionally high purity.

    Pros

    • Convenient to use
    • Cost effective
    • Provide healthy drinking water safe for consumption
    • Remove fluoride and lead
    • Remove bacteria and viruses
    • Can be used for both point-of-use (POE) and point-of-entry (POE) applications
    • Can produce relatively large volumes of filtered water
    • Usually don’t require an extra source of energy
    • Filters last longer because only water used for direct consumption gets filtered

    Cons

    • Produce wastewater
    • Water flow can be slow (Solution: Add pump to increase pressure)
    • Strip away minerals (Solution: Add mineral salt or use remineralization stage)
    • Might require installation by a professional
    • Higher maintenance requirements
    • Is likely to require additional pre-treatment when used on well or very hard water

    Regarding pre-treatment: RO membranes are very delicate. Contaminants such as chlorine can damage them and shorten their lifespan significantly. This is why most RO home purifiers feature at least 2 to 3 different pre- stages that water has to run through before it gets in contact with the membrane itself.

    • Sediment pre-filters remove sand, dirt and all other particles with a size larger than 5 (1) microns.
    • Carbon pre-filters reduce tastes, odors and chemicals.

    Nevertheless, depending on the condition of your feed water, this might not be sufficient. If so, you’d have to pair reverse osmosis with a whole house purification system or a water softener.

    Home Master TMAFC-ERP

    Home Master TMAFC-ERP

    #1 RO System: Home Master TMAFC-ERP

    •    Price: $$$
    •    Filter Stages: 7
    •    Gallons per Day: 75
    •    NSF Standard: 42
    •    Annual Costs: ~$85.00

    What We Like

    The Home Master TMAFC-ERP Artesian Full Contact is one of the few RO systems made in the U.S. and is backed by a 5-year limited warranty with outstanding Amazon customer reviews.

    The system features a sophisticated 7-stage purification process that provides you and your family with up to 75 gallons of safe and crystal clear drinking per day, so you never run out of it.

    Water which is free from sediment, dust, rust, tastes & odors, chlorine, chloramine, disinfection byproducts, fluoride (97.7%), lead (99.3%), nitrates (80.0%), cysts (99.99%), chromium 6 (99.1%) and VOCs.

    Also, the water does NOT lack healthy calcium or magnesium thanks to 2 remineralization stages.

    But what really sets the system apart from the competition is the fact that it comes with a permeate pump. The pump enhances water efficiency, purity and flow rate and at the same time reduces wastewater production from approximately 4 down to 1 gallon for every gallon of filtered water.

    Bottom line: The Home Master TMAFC-ERP is a highly economic RO system and a real money saver.

    On top of that, everything you need for the setup is included in the package. The system is made for DIY installation with a detailed instruction manual, a 6-part video series on YouTube, professional live support and color-coded tubing. No need to call a plumber.

    The same goes for maintaining the system. Thanks to their modular design, filters can be changed within a couple of minutes. Capacity: 2,000 gallons or 12 months.

    What We Don’t Like

    In addition to Standard 42, we would have liked further NSF certifications for contaminant reduction rates.

    You might find the instruction manual unclear at times.

    Our Verdict

    As far as RO systems are concerned, this is hands down the best water purifier on the market.

    Other RO Purifiers

    There are 3 other RO purification systems that could be of interest to you.

    iSpring RCC7AK

    No. 1 is the iSpring RCC7AK 6-stage system, an all-time best seller which also comes with a remineralization stage that adds a mix of healthy minerals back into your water and thereby increases water alkalinity.

    Another benefit is the leak sensor that triggers an alarm sounds when detecting moisture at the bottom of the unit.

    The system itself is tested and certified against NSF Standard 58. Time to say goodbye to

    • 96% lead,
    • 94% fluoride,
    • 98-99% waterborne pathogens and a whole bunch of other impurities.

    Compared to the Home Master TMAFC-ERP, system maintenance requires a little more effort. The filters need to be changed every 6 to 12 months. In order to do that you have to shut off the water supply and depressurize the whole unit so that you can remove the filter housings, which by the way are prone to leaking.

    APEC-ESSENCE-ROES-50

    No. 2 is APEC’s ESSENCE ROES-50 Top Tier which is also one of the best selling reverse osmosis purifiers on Amazon. It provides great-tasting drinking water, has a good price-performance ratio and is low in maintenance – both in terms of time involvement and costs.

    The only drawback is that this system, too, does not feature a modular design, so replacing the filters can be a bit more challenging and messy, but not too much.

    In case of leakages, a 1-year satisfaction guarantee got you covered. So does the APEC product support team.

    Olympia Water Systems OROS-50

    No. 3: The Olympia Water Systems OROS-50. The main reason why we like this unit so much is because it combines decent filtration with a very low price tag.

    Disadvantages are that the factory connections are low quality and require proper setup to stop leaking. Also, water flow is slower than with most other purifiers.

    UV water purifiers are an effective means to disinfect well or municipal water supplies. They use ultraviolet light to destroy up to 99.99% of waterborne microorganisms. The light attacks the DNA of viruses, bacteria, protozoa, mold and some cysts to eliminate their ability to reproduce rendering them harmless.

    A UV system’s effectiveness to kill microorganisms depends on its ability to provide an adequate dosage of UV light. 30 mJ/cm2 is considered enough for drinking water applications.

    Pros

    • Quick, low-cost and reliable
    • EPA approved to be environmentally friendly and chemical-free without creating any harmful disinfection byproducts (unlike chlorination for example)
    • Do not alter the taste, smell or pH of water
    • Can be used for both point-of-use (POE) and point-of-entry (POE) applications
    • Even kill chlorine-resistant pathogens such as giardia and cryptosporidium
    • Easy to install and use – set and forget
    • Very low maintenance requirements

    Cons

    • Do not remove any commonly found contaminants from water such as chlorine, pesticides and heavy metals
    • Do not work with water containing contaminants larger than 5 microns, so pre-treatment might be necessary
    • Not suited for emergency situations as it operates on electricity

    Regarding pre-treatment: We suggest you pair UV light with another water filtration method for complete purification and the safest drinking water. A pre-filter system that features reverse osmosis or a regular sediment (5 micron) or activated carbon filter would be perfect. In cases of severe water hardness, consider adding a softening device.

    HQUA-OWS-124

    HQUA-OWS-124

    #1 UV Light Purifier: HQUA-OWS-124

    •    Price: $$$
    •    Watts: 55
    •    Flow Rate: 12 gpm
    •    NSF Standard:
    •    Annual Costs: ~$60.00

    What We Like

    The HQUA-OWS-124 is a whole house UV water purification system that inactivates harmful microbes within 1 to 2 seconds delivering 12 gallons of disinfected water per minute – enough for a family of 5 to 6.

    When assembled, the 55W UV lamp is contained in a food-grade and solid stainless steel chamber and lasts for about 9,000 hours before it needs replacement.

    If you do the math, one bulb has a lifespan of a little more than 1 year, which is great, because it means less for you to worry about.

    As far as the installation goes, it’s pretty easy and straightforward and can be done in a relatively short amount of time. Just make sure that you have (A) Teflon tape at the ready and (B) enough space to mount the unit.

    Adequate clearance allows for an easy change of the UV lamp later on (about 8 feet should be fine).

    Then turn off your water supply and follow the provided instructions. Alternatively, go on YouTube and check out some of the various installation videos.

    Once you are done, make sure there are no leaks. The handy indicator lights will tell you if everything is working fine.

    More advantages:

    • HQUA’s customer support team does a great job at answering all your questions.
    • For every missing or broken part the seller offers double replacements.
    • 2 extra UV tubes are included in the package.

    What We Don’t Like

    We would have preferred NSF certifications for this product that guarantee optimum purification performance.

    Also, the plastic mounting brackets look a little cheap.

    Our Verdict

    The HQUA-OWS-124 is great for anyone struggling with water pathogens. You won’t regret buying this product.

    Remember: If your water contains too many contaminants, a pre-filter system is required for the UV disinfection to be effective.

    Other UV Purifiers

    We found 2 other UV water purifiers that we would like to introduce to you.

    UV Light System by Wholesale Market LLC

    The first one is sold by Wholesale Market LLC. It’s another 12 gpm/55 W system that comes with 2 extra bulbs, 1 extra ballast and 1 extra quartz sleeve. In other words, you should be good for at least 2 years before you need to buy any replacement parts.

    The system works great without causing leaks and putting everything together is not rocket science – no tools required. Customer support? Reliable and quick to respond. What else could you ask for?

    Ronaqua Ultraviolet Light Water Purifier

    A more affordable alternative is the Ronaqua Whole House UV Sterilizer. It’s 12 gpm with 55W and 2 replacement bulbs. However, it seems like this system is cheap for a reason. It’s lower in quality and known to cause some issues:

    1. The plastic clamps won’t properly hold the unit when mounted vertically.
    2. For some customers, the ballast burned out after about 1 year of use.
    3. For others, corrosion lead to leakages.

    Other than that, the customer service leaves somewhat to be desired.

    All in all, buying this UV water purifier will save you money, but it’s also a bit of a gamble and could lead to frustration.

    •    Watts: 750
    •    Capacity: 1 gal
    •    Cycle Length: 4 h

    Next in our water purifier reviews: Distillers. Now distillation is one of the oldest and yet most effective water purification method used today. About 15% of U.S. bottlers rely on it.

    In the process, water is heated to its boiling point and vaporizes. As it rises, it leaves most contaminants behind in the boiling chamber and enters a cooling coil where it cools down and condenses back into liquid. Finally, the purified H2O is collected in a separate container.

    Pros

    • Properly distilled water is the purest water possible
    • Remove fluoride and lead
    • All microorganisms are destroyed
    • Distilled water can be produced from almost any water source

    Cons

    • Energy intensive so less cost-effective
    • Distilled water lacks minerals and therefore might taste flat (Solution: Add mineral salt)
    • Distillers do not remove volatile contaminants with a low boiling point like pesticides or herbicides, so additional treatment might be necessary (e.g. carbon filtration)
    • Require periodic cleaning

    Nutriteam’s Megahome Stainless Steel Countertop Distiller

    Megahome MH943SBS Purifyer

    #1 Distiller: Megahome MH943SBS

    •    Price: $$
    •    Watts: 580
    •    Capacity: 1 gal
    •    Cycle Length: 5½ h

    What We Like

    First things first: Megahome water distillers by Nutriteam have been around for years, even decades. It’s the most popular and top selling brand on the market.

    This model with the number MH943SBS is high-quality and can provide a full gallon of purified water every 5 and a half hours. All you need to do is fill up the boiling chamber, press a button and wait (or go to bed).

    The system uses 580W or 0.58kW to operate. So if you distill 1 gallon of water per day, the monthly costs amount to $10 – $15, depending on how much you pay per kWh.

    Compare that to about $45 for bottled water and it becomes obvious that although distillation runs on electricity you will make significant savings.

    What we also like is that, with this distiller, nowhere in the process will your water get in contact with any plastic parts. This is often the case with cheaper models which can cause contamination issues.

    What’s more, in the glass nozzle sits an activated carbon filter that removes any volatile substances before the water enters the carafe (also made out of glass). An extra 6-month supply of filters is included in the package.

    And lastly, the distiller is UL (Underwriters Laboratories) approved which guarantees that it complies with important safety standards. A high-temperature thermostat prevents overheating and ensures automatic shut-off when all the water is boiled out.

    Did we mention the excellent customer feedback on Amazon?

    What We Don’t Like

    One important detail to note is that there is no on or off switch. So if you don’t want the Megahome MH943SBS to run until all the water has vaporized, get yourself a timer switch and set it to about 5 hours. This will leave enough water inside and help with two things:

    1. It increases the distiller’s longevity.
    2. It makes the cleaning so much easier as there won’t be any burned deposits.

    Our Verdict

    You can’t go wrong with the Megahome MH943SBS. It’s as good as home water distillation can get.

    Remember: This unit distills no more than 1 gallon at a time. Even if you run it twice per day, this will hardly be enough for 4 or more people.

    Other Distillers

    Megahome MH943TWS

    Almost identical to the Megahome MH943SBS is the Megahome MH943TWS. In a nutshell:

    It features an enameled metal exterior instead of one made from stainless steel. Therefore, it’s a tad cheaper. Customer ratings are equally positive.

    However, there seem to be two issues with this distiller. For one, some customers reported that it added an unpleasant plastic or metal taste to their water. The root of the problem seems to be the steel tubing. Anyway, it totally defeats the purpose of a distiller. And secondly, the steel tank might start leaking after a while.

    Mophorn Pure

    The Mophorn Pure Water Distiller is the cheapest of its kind. It features a simple design and is easy to use. And just like the two Megahome distillers above, this unit purifies up to 1 gallon of water per cycle.

    The main difference is that the Mophorn runs on 750W instead of 580W. So the power it needs is significantly higher, however, the distillation process is also considerably faster (4 hours). In the end, it won’t make much of a difference on your electricity bill.

    Food-grade stainless steel interior? Check! Activated carbon filter to get rid of VOCs? Check! High-quality water container? Not really… Yes, it’s food-grade and BPA-free plastic, but it will make your water taste and smell like chemicals. Even thorough cleaning does not bring any improvement. Therefore, we highly suggest you to throw the container right in the trash can and replace it with a glass one.

    As a major flaw, we read about units breaking down completely after only a couple of months use.

    ROVSUN

    In terms of price and quality, the ROVSUN Countertop is sort of in-between the Megahome water distillers and the Mophorn.

    It features a stainless steel interior and a glass container to prevent contaminants from re-entering the water, plus a carbon filter stage for volatile impurities. All is covered by a 1-year guarantee, which might come in handy as the glass container seems a little fragile.

    What we don’t like is that especially when you first start using the device, it can be hard to get rid of the oily deposit in the distilled water that might be some leftover from the manufacturing.

    Water purifier pitchers are probably the most popular type of water purifiers for home use. They are great if your water already has a certain degree of purity and you just want to give it a finishing touch by removing residual tastes and odors.

    Most models use disposable cartridges containing activated carbon for the adsorption of chlorine, a range of volatile organic chemicals and some disinfection byproducts. A handful of pitchers can also reduce lead and fluoride content and other pollutants with health effects.

    Pros

    • Low initial costs
    • No installation required (great for renters)
    • Can be stored in refrigerator for cooling
    • Simple to use and clean
    • Portable

    Cons

    • Do not remove the majority of potential contaminants
    • Inconvenient due to limited water storage volume
    • Costs can add up over time
    • Purification is slow and filters can clog easily
    • Can introduce bacteria into your water when used incorrectly

    Aquagear

    Aquagear Pitcher

    #1 Purifier Pitcher: Aquagear

    •    Price: $
    •    Cups: 8
    •    Filt. Capacity: 150 gal
    •    NSF Standard: 42, 53
    •    Replacement Costs: $$$

    What We Like

    A water purifier pitcher that removes 90% fluoride, 99.9% lead, 99.9% arsenic, 99.9% chlorine and chloramine and 99% of 50+ VOCs including dangerous disinfection byproducts? That’s unheard of…

    No, it’s not! In fact, the Aquagear pitcher which has been tested against NSF standards 42 & 53 removes more than 89 different pollutants from tap water.

    Its filters are made in the USA and last for approximately 150 gallons or 6 months of use – much longer than what you get with most other pitchers – for maximum convenience.

    You also get a lifetime guarantee on the pitcher itself. So when it breaks, simply get in touch with Aquagear and get a free replace. How cool is that?!

    What We Don’t Like

    The downside of a thorough purification is that it takes more time. And because purifier pitchers rely on gravity to push the water through their filter element, “long” can mean reeeally long.

    Our Verdict

    Although the Aquagear is one of the most expensive pitchers out there, we simply love it. Based on our reviews, its quality is second to none both in terms of design & construction and even more importantly water pureness.

    Other Pitchers

    Brita Everyday

    The Brita Everyday made it on our list not because of outstanding purification performance, but because it’s highly popular among users due to its low price.

    It can fill up to 10 cups of water at a time, which is not bad even for whole families. Also, its functional design makes the pitcher easy to use. The lift-off lid allows for easy filling and cleaning of the upper reservoir.

    On a side note: For the filtering element, you can choose between Brita’s Standard and Brita’s Longlast filter.

    • The Brita Standard is rated at 40 gallons and removes chlorine taste and odor and reduces a number of heavy metals, lead not among them.
    • The Brita Longlast is rated at 120 gallons and can handle lead, asbestos and cadmium among other contaminants.

    Taking into account the much higher capacity, it makes more sense to choose the Brita Longlast over the Standard, although the latter is a tad cheaper.

    pH RESTORE Alkaline Water Pitcher

    If you had to describe the pH RESTORE Alkaline Water Pitcher in one sentence, it would be: It’s a little more expensive, but it has some nice additional features making it worth the price tag.

    For one, it alkalizes your water (who would have guessed) by adding healthy minerals such as calcium and selenium to it.

    Above that, using the optional PH002 cartridge, the pitcher eliminates 99.9% of waterborne pathogens and 80% fluoride. In addition, it reduces chlorine, chloramine, VOCs, some heavy metals – you name it. Plus the 264 gallons filtering capacity will last you a long time and helps to save money further down the line.

    Flaws? The filters are prone to clogging and cleaning the pitcher can be a headache.

    As the name suggests, an under sink water purification system is any system that gets installed under the kitchen sink. Examples are reverse osmosis machines, single-stage purifiers based on carbon media, and multi-stage units that might combine sediment and carbon treatment with ion exchange and what not.

    The majority of under sink purifiers use a dedicated faucet, which requires you to drill a second hole in the sink deck or countertop in case there isn’t one already. The benefit here is that you can choose to use purified water only when you need it. Consequently, filter cartridges are going to last much longer.

    Inline systems, on the other hand, don’t use a separate faucet making the installation a lot easier. The downside is that they purify all the cold water that you draw from your regular kitchen tap.

    Pros (Only Non-RO Systems)

    • Convenient to use
    • Cost effective
    • Provide healthy drinking water safe for consumption (not all)
    • Remove fluoride and lead (not all)
    • Remove bacteria and viruses (not all)
    • Save precious space on your kitchen counter
    • Different purification technologies to choose from
    • Can produce relatively large volumes of filtered water
    • Don’t require an extra source of energy

    Cons (Only Non-RO Systems)

    • Water flow can be slow
    • Might require installation by a professional
    • Higher maintenance requirements

    Woder 10K-Gen3

    Woder 10K-Gen3 Home Purifer

    #1 Under Sink System: Woder 10K-Gen3

    •    Price: $
    •    Filter Stages: 1
    •    Flow Rate: 2 gpm
    •    NSF Standard: 42
    •    Extra Faucet:
    •    Annual Costs: ~$16.00

    What We Like

    If you are looking for a compact inline water purification system that will provide you with clean drinking water right from the tap, look no further.

    The best selling Woder 10K-Gen3 is suited for mild cases of city water contamination and uses activated carbon media to purify – believe it or not – about 10,000 gallons of water.

    What’s more, the system does not require any maintenance at all, which means that you have to set it only once and then you can forget about it for the next 3 years.

    It improves water aesthetics and is capable of removing 99.9% of lead and chromium-6. Above that, it eliminates a large chunk of other heavy metals and VOCs.

    The installation couldn’t be more simple. It won’t take you more than 5 to 10 minutes.

    By the way, Woder offers a full satisfaction guarantee in case you don’t like the system.

    What We Don’t Like

    Except for Standard 42, we searched for NSF certifications in vain.

    Our Verdict

    Great price, great performance, and hundreds of positive customer ratings for backup. This really is a no-brainer.

    Other Under Sink Systems

    CuZn UC-200

    The CuZn UC-200 is another one of our favorites. It’s manufactured in the U.S. with a filtering capacity of up to 50,000 or 5 years with absolutely no maintenance requirements. Plus it’s bacteriostatic to make sure that no bacteria or mold accumulate in the system over time.

    The 3-stage purification process helps you to get rid of a wide range of organic and inorganic pollutants.

    Installation? Doesn’t take more than a couple of minutes.

    And last but not least, within the first 90 days of receiving the product, you can revoke your purchase and get a full refund. After that, you have a 5-year warranty protection in case something goes wrong.

    Ecosoft 3-Stage

    One of the cheapest multi-stage under sink water purification systems is sold by Ecosoft. The 3-stage machine costs little more than many of the single-stage units and much less than the average RO system.

    And yet, the Ecosoft removes a wide range of contaminants, from chlorine and its byproducts to heavy metals including aluminum and lead, providing crystal clear and refreshing drinking water.

    A low 400-gallon filtration capacity is less convenient and so is the low flow rate of 0.25 gpm.

    With the exception of autarkic gravity filters, countertop water purifiers directly connect to your kitchen faucet. They come in all forms and sizes and apply different purification technologies, most importantly carbon treatment followed by gravity filtration and reverse osmosis.

    Pros

    • Cost effective
    • Simple to use and clean
    • Portable
    • No need to make permanent changes to your plumbing system (great for renters)
    • Install within a couple of seconds
    • Provide healthy drinking water safe for consumption (not all)

    • Take up space on your countertop
    • Might not connect to your kitchen tap

    APEC Portable RO-CTOP

    APEC Portable RO-CTOP Home Purifer

    If you want the countertop system with the most thorough purification, definitely go for APEC’s RO-CTOP. The reverse osmosis unit provides pure H2O while still being portable and lightweight.

    The maximum water output is 90 gpd, which is enough to supply a whole village with refreshing drinking water.

    The only flaw is that filter replacement costs are above average.

    Home Master TMJRF2 Jr F2

    The Home Master TMJRF2 Jr F2 is for tighter budgets and thanks to its compact design perfect for small kitchen owners. It makes even the dirtiest tap water taste great and installing the thing doesn’t take more than a couple of minutes at max.

    The manufacturer claims that reduction rates for fluoride and lead are 93%. Unfortunately, we miss any performance data sheets.

    And lastly, filters need replacement every 3 – 5 months, which is not too bad, but definitely more frequently than what we are used to.

    Big Berkey BK4X2 Gravity Filter System

    Big Berkey BK4X2 Gravity System

    Big Berkey BK4X2 Gravity System

    •    Price: $$$
    •    Fluoride Reduction: 99.9%
    •    Lead Reduction: 99.0%
    •    NSF Standard:
    •    Filter Lifetime: 1½-3 Years
    •    Annual Costs: ~$40.00

    Berkey as a company and brand is a synonym for high-quality gravity fed water purification devices. As the name suggests, this type of purifier is based on gravity, which pulls water through the filter elements – just like a filter pitcher.

    All you have to do is pour water into the top reservoir, wait a few minutes and use the bottom spigot to dispense clean water from the storage tank.

    Pros

    • Cost effective
    • Great for removing chlorine, chlorination byproducts, pesticides and VOCs
    • Remove fluoride and lead (not all)
    • No installation required (great for renters)
    • Portable
    • Long-lasting filters
    • Ideal for emergency situations as almost any fresh water source can be used
    • Don’t require an extra source of energy

    Cons

    • Higher initial investment
    • Water flow can be slow
    • Higher maintenance requirements
    • Inconvenient due to limited water storage volume

    The Big Berkey BK4X is specialized in lead (99.0%) and fluoride (99.9%) reduction.

    It purifies 3.5 gallons of water per hour and can store a little more than 2.2 gallons in its bottom tank. This avoids long waiting times and makes it perfect for both single households and families.

    The filter elements have varying capacities between 1,000 and 3,000 gallons, which is going to last you for at least 1 year. And even better than that, they are surprisingly cheap.

    Faucet water purifiers work with different layers of filter media to reach maximum contaminant reduction.

    First, larger particles are blocked in a sediment layer. Next, activated carbon traps chlorine and other chemicals. With some purifiers, a mineral resin reduces lead and other heavy metal content through ion exchange.

    Pros

    • Low initial costs
    • Simple to use and clean
    • Portable
    • No need to make permanent changes to your plumbing system (great for renters)
    • Install within a couple of seconds
    • Remove lead
    • Don’t require an extra source of energy
    • Allow switching between filtered and unfiltered water

    Cons

    • Unsightly
    • Take up space above/in your kitchen sink
    • Might not be compatible with your kitchen tap
    • Do not remove all contaminants such as fluoride
    • Costs can add up over time
    • Water flow can be slow

    •    Annual Costs: ~$40.00

    If we had to name one faucet water purifier as our top recommendation for safe and great-tasting drinking water in your home, it would definitely be Brita’s On Tap Complete.

    The reason being that the device is NSF certified to eliminate a wide range of potentially harmful water pollutants, while still being affordable.

    To name a few pollutants that pose a health risk, the filter takes on lead and asbestos (>99.0%), cysts, VOCs, and of course chlorine and the much dreaded chlorination byproducts.

    Other advantages are the built-in light indicator that notifies you when a filter cartridge needs replacement, the option to switch back and forth between purified and unpurified water to increase filter longevity and save money, and the simple setup.

    Cons are the low-quality connectors that lack a tight enough grip and incidents with minor leaks.

    Other Faucet Purifiers

    Other popular faucet purifiers are the Culligan FM-25 and the PUR Advanced PFM400H, although there is not much of a difference here to be honest, especially between the Brita On Tap and the PUR Advanced.

    They are similar in price, filtration capacity and maintenance costs. And most importantly, they are comparable in terms of contaminant reduction rates. Only the Culligan falls a little behind in this regard.

    In direct comparison to the PUR advanced, the main benefit of the Brita On Tap Complete is that it’s more sturdy and doesn’t cause that much trouble with leaks.

    In the first section, we reviewed the best water purifiers for sale. Next we are going to answer some of the most common questions our readers have about water purifying systems in general.

    What Is a Water Purifier and How Does It Work?

    A home water purifier removes undesirable chemicals, biological contaminants, and suspended solids and gases from water with the goal to make it fit for a specific purpose. That’s usually drinking, cooking and/or washing.

    Thereby, the basic functionality of a water purifier machine is always the same:

    Water is channeled through a filter medium or membrane that traps, exchanges or blocks specific substances.

    The problem, however, is that there are so many different types of purifiers that all vary in the way they work.
