3. The Runner-Up for Tap Water: US Water Systems BodyGuard Plus Whole House Water Filtration System

We wanted to provide you with an alternative for whole house municipal water treatment in case you don’t like the SpringWell CF for whatever reason. Thus, let us introduce you to the BodyGuard Plus whole house water filter system by US Water Systems.

It’s a tad more expensive than the SpringWell, but still one of our top choices. That’s because we have catalytic carbon combined with granular activated carbon for removal or reduction of chemical contaminants like chlorine, chloramine, pesticides, VOCs, THM, and many others, resulting in great-tasting water that’s also healthy for your hair and skin. Plus, the pre-filters are top-notch…

USWS BodyGuard Plus Whole House Water Filtration System

Price:$$
Filter Capacity:5 Years
Water:10-20 gpm
Annual Cost:$45-100
Warranty:Lifetime, 10 Years, 5 Years

Our Rating

Pros

  • American Made.
  • Provides (drinking) water of the highest quality.
  • Catalytic carbon and coconut shell granular activated carbon contained in the main tank do the bulk of the contaminant removal. They remove hundreds of contaminants, primarily chemicals: Chlorine/chloramine, pesticides, herbicides, pharmaceuticals, industrial solvents, THMs, PCB, VOCs.
  • 2 optional pre-filters to choose from. Both prolong the life of the carbon filter media:
    • The Interceptor is a 5-micron sediment filter outside with pleated material made up of nano fibers inside. These nano fibers literally attract contaminants including bacteria (99.9%), lead, chromium 6, and sediments down to the sub-micron level like a magnet due to their Zeta potential (51 millivolts).
    • The Magna is a high-quality 5-micron pleated sediment pre-filter used to trap dirt.
  • Whole house water filter comes in 3 sizes:
    • 117-BGP-100 delivers 10 gallons per minute (1-3 bathrooms).
    • 117-BGP-150 can process up to 15 gpm (4-6 bathrooms).
    • 117-BGP-200 for up to 20 gpm water flow (7 or more bathrooms).
  • You can track and monitor your water usage connecting the head unit to your smartphone. The Waterlogix app to pair the devices is free.
  • Simple, easy Installation.
    • Package includes a bypass valve.
  • The carbon can be used for hundreds of thousands of gallons or even millions, depending on the level of contaminants in your water. US Water Systems recommend replacement after 5 years. Both pre-filtration cartridges last about 1 year. Hassle-free maintenance guaranteed.
  • You get a warranty lifetime on the tank, 10 years on the valve and electronics, and 5 years on the carbon filter media.

Cons

  • Sediment filter replacements are more expensive than with the competition.

4. The Runner-Up for Well Water: USWS Matrixx inFusion Iron and Sulfur Removal System

As an alternative to the SpringWell WS for well water treatment, we recommend the Matrixx inFusion by US Water Systems.

Using hydrogen peroxide for oxidation in combination with catalytic carbon, the whole house filtration system is designed for removing very high levels of iron, hydrogen sulfide, and manganese (the company says the system excels at 5-6 ppm iron and/or sulfur or higher). It can even handle iron and sulfur bacteria without issues.

Matrixx inFusion Iron and Sulfur Removal System

Price:$$$
Filter Capacity:Many Years
Water:10-25 gpm
Annual Cost:$200-400
Warranty:Lifetime, 10 Years, 5 Years

Our Rating

Pros

  • Provides rust-free and sulfur-free water. Also removes or reduces sediment, sand, silt, and cloudiness.
    • Protects plumbing, fixtures, and appliances.
  • When water is used, the water meter notices and signals the chemical pump to inject hydrogen peroxide into the water stream based on flow rate and settings. The hydrogen peroxide instantly oxidizes any iron, manganese, and sulfur precipitating it from solution. Thus, as the water passes through the catalytic carbon filter, all oxidized contaminants are removed.
    • Being a very strong oxidizer, the hydrogen peroxide also eliminates odors and microorganisms.
    • There are no unwanted byproducts. Hydrogen peroxide (H2O2) disintegrates into oxygen (O2) and water (H2O). This is much safer than using chlorine.
  • Every few days, all accumulated contaminants are automatically backwashed from the filter media during regeneration.
    • A Vortech tank plate increases backwashing efficiency: Up to 30% less wastewater. And it eliminates channeling for continuous performance and long catalytic carbon life.
  • Filter system comes in 4 sizes:
    • 10 gpm peak water flow for 1-2 bathrooms.
    • 15 gpm ideal for 2 to 3.5 bathrooms.
    • 20 gpm for 4-6 bathrooms.
    • 25 gpm for 7 bathrooms or more.
  • Package includes all accessories you need: 15-gallon peroxide tank, injection panel (Stenner Econ Series chemical pump + precision water meter), 5 gallons NSF-approved H2O2 (OxiPro-7).
  • Easy to clean chrome tank protector.
  • Easy installation with good step by step directions. Built-in bypass.
  • 30-second programming with smartphone. WaterLogix app also allows you to track and monitor all water usage using your mobile device.
  • Virtually maintenance-free.
  • Lifetime warranty on filter tank, 10 years on control valve, 5 years on peroxide injection panel.

Cons

  • Due to the nature of the filtration process, it entails an annual hydrogen peroxide bill of around $200-400.

5. Crystal Quest SMART Whole House Water Filter

Crystal Quest’s SMART Whole House Water Filter is another system providing an unlimited pure water supply to your kitchen, bathrooms, and the rest of your home.

What makes it special is the combination of 7 different filter media for broadest contaminant removal – suited for both city water and well water.

Pros

  • Crystal Quest water filters are Made in USA.
  • First comes a 5-micron sediment pre-filter. It traps floating solids such as sand, rust, and silt. It’s used to prevent fouling of the other filter stages.
  • 7 types of filter media are found in the main tank: Granular activated carbon, catalytic carbon, Eagle Redox Alloy 9500 (KDF), Eagle Redox Alloy 6500 (KDF), ion exchange resin, ceramic balls, and tourmaline balls. Combined, they filter out chlorine and chloramine, DBPs, pesticides and other chemicals, heavy metals including lead, sulfur gases, and all kinds of other organic as well as inorganic impurities. The treatment process also provides for balanced water pH and microorganisms have no chance of accumulating inside the system.
    • Naturally, this improves water aesthetics by a great bit.

Pros

  • First, a 5-micron PP sediment pre-filter captures dirt so it doesn’t foul the carbon and KDF media beds.
  • The Rhino EQ-1000 and Rhino EQ-600 use activated carbon to reduce or remove chemicals, like chlorine and pesticides, and VOCs.

    • There is an NSF standard 42 certification for 96.9% chlorine removal.
  • Rhino EQ-Well-UV uses catalytic activated carbon. It’s even more effective than regular activated carbon against all kinds of chemicals plus sulfur gases. Sulfur gases are also further removed by KDF-85 which is also effective against heavy metals. Lastly, a 0.35-micron post-filter catches any remaining particles and a UV filter inactivates 99.99% of microorganisms commonly found in well water.
  • 3 Rhino versions available with different filtration capacities:
    • Rhino EQ-1000 lasts for 1M gallons of chlorinated city water (10 years).

8. Our #1 Cartridge-Based Whole Home Water Filter for Tap Water with Chlorine: NU Aqua 3-Stage Whole House Water Filtration System

In our opinion, the NU Aqua 3 Stage Whole House Water Filtration System makes the best choice if you are on chlorinated city water and you prefer whole house water filters working with filter cartridges. Just like the 3 products reviewed above, the NU Aqua provides clean water for the entire house.

The big difference, however, is that – and this goes for cartridge water filters in general – the system is much lower cost upfront. In fact, it’s surprisingly cheap, especially considering all the extra features. Bottom line: 4.5 stars!

Our Rating

Pros

  • High quality water filter is one of the best of its kind. People are very pleased with the results they see: Improvement in water quality right after installation – no more iron staining, clean water taste, and fresh smell.
  • No huge single payment upfront.
  • Filter stage 1 is a multi-gradient density sediment filter (25 – 10 – 5 – 1 micron nominal) that traps rust, sand, silt and other particles. It makes your water crystal clear and takes out harmful contaminants including bacteria and cysts.
    1. Manufacturer says has triple the dirt holding capacity of similar sized filters.
  • Filter stage 2 is a specialized iron filter. Reduces up to 3 ppm ferrous (clear-water iron) and ferric (red-water iron).
    1. Also helps with manganese and sulfur but both lower the filter life at up to 2-6 times the rate of iron. Ideal conditions: No hydrogen sulfide, no iron bacteria, and manganese below 1 ppm.
  • The post-filter uses granular activated carbon (20 micron nominal) to give the water a final polish removing chlorine, chemicals like pesticides, VOCs, and residual tastes and odors among other things.
  • Optimal pH level is above 7.0.
  • Whole house water filter shouldn’t be used with microbiologically unsafe water or water containing viruses without further treatment.
  • Filters up to 15 gpm which is plenty of water and sufficient for homes with 4+ bathrooms.
  • Easy to install if you have any prior plumbing experience or are simply handy with tools.
  • Low maintenance which is convenient. Naturally, how frequently one has to change filters depends on water usage and quality. Most users are probably looking at biannual filter changes.
  • Customer support is impressive. You can send in your well water report and get recommendations from the knowledgeable staff members.
  • Two-year warranty.

Cons

  • No built-in bypass.
  • Replacement filters are quite pricey.

10. Our Number One Sediment Filter: Custom Home Master Three-Stage Water Filter System

If you want to remove nothing but sediments from your water you can do so using a custom Home Master three-stage water filter. The setup uses step-down filtration ideal for applications with several sediment water problems.

Step-down filtration? It means multiple filters in a row, each stage with a lower micron rating and thus a more thorough filtration than its predecessor. This approach prevents premature clogging of the finer filters. In our case, we use three 4.5″ x 20″ pleated sediment filters rated at 30, 5 and 1 micron.

Pros

  • Best water filter for city and well water high in sediments.
  • 30-micron and 5-micron sediment filters filter out larger contaminants in your water: Silt, sand, rust and dust.
  • 1-micron filter also filters out cryptosporidium and giardia.
  • Each of the 3 water filters features a pleated design for maximum filtration capacity.
  • At first glance they appear way more expensive than competitor filters. However, the polyester material is more durable, and resistant to bacteria and chemicals in water. This allows you to clean and reuse every single cartridge 1 to 6 times before tearing – a huge money saver!
    • Do not reuse when treating cryptosporidium and giardia.
    • Thanks to 20″ big blue standard size you can go with cheaper aftermarket filters if need be.
  • This setup is not for microbiologically unsafe or non-potable water or water containing viruses without proper disinfection.
  • Absolutely no need to worry about flow rates. You’ll have more than enough water even if you’re living in a mansion.
  • Installing and maintaining this whole house water filter is simple.
  • Best overall customer support.
  • 2-year warranty.

Cons

  • No built-in bypass.

11. Cheap Whole House Water Filter System: 3M Aqua-Pure AP903

The last of our whole house water filter reviews features 3M’s Aqua-Pure AP903. It’s not the best whole house water filtration system by any means, but it’s a solid alternative for everyone on a tight budget; a system that makes your water look, smell, and taste delicious.

Since it won’t help you get rid of most smaller contaminants like heavy metals and pesticides, however, it’s best suited for people who already have fairly clean water – municipal water ideally.

Our Rating

Pros

  • The AP903 whole house water filter applies carbon block filtration (5 microns nominal) with a non-woven pleat media to remove sediment, chlorine, and chemical contaminants in water. This improves water taste and smell and increases the life of water heaters and other appliances.
  • Can process an exceptionally high amount of water per minute, up to 20 gpm peak flow, ideal for large homes with multiple bathrooms.
  • 304 stainless steel head is corrosion resistant providing a long service life and won’t affect the taste of drinking water.
  • Easy installation. The slim design allows for placement at the main water supply even if space is limited.
  • Filter can be replaced with a quarter turn – quick and easy with no tools needed.
  • Head comes with a 25-year warranty.

Cons

  • Minor disadvantage is a small percentage of users have to change the filter way more frequently than indicated by the manufacturer. It’s supposed to last 100,000 gallons or 12 months. Theirs was clogged after about 30 days (15,000 gallons) resulting in a significant water pressure drop.
    • Too expensive to replace at such frequency so you may need additional pre-treatment to get rid of particles that could clog the 3M Aqua-Pure whole house water filter easily.

Buyer’s Guide: Considerations Before You Buy a Whole House Filter

Before you go out and buy a water filtering solution for your home, consider this:

Which Whole House Water Filter Do I Need? Test Your Water Quality!

First things first. You need to find out more about the quality of your water. This allows you to purchase a whole house water filter capable of dealing with all or at least most of the contaminants lurking in it.

Are you on well water or on municipal water a.k.a. city water? If your water is sourced from a well, do you have access to a water quality report? If not, your best option is to send a direct sample to an independent lab. Alternatively, you can purchase a well water test kit which gives you a rough idea of what you are facing (hard water level, iron and other heavy metals, etc.).

If you’re on city water you can go here or visit this page and search for your utility. All reports in both databases are free!

Whole House Water Filter Types

There exist different types of whole house water filters.

Whole house water filters for city water usually focus on removing sediments, chlorine, chloramine, disinfection byproducts, and various chemicals responsible for creating unpleasant odor and taste. These systems are carbon-based and might even contain additional KDF media to reduce heavy metals and keep bacteria and algae in check. Units making use of bone char can even remove fluoride from water with enough contact time (see best fluoride water filters here).

Filters specialized in well water treatment will usually eliminate iron, manganese, and sulfur, which are the most common contaminants here. One example is the SpringWell WS using air injection oxidation + greensand filter bed. In case your well is also polluted with contaminants from agricultural runoff – think fertilizers, pesticides, herbicides – consider adding carbon filtration.

You’re living in an older house and have detected lead in your water? Check our guide in which we select the best lead water filter.

How about a salt-based or a salt-free water softener? Well, an (ion exchange) water softener has the purpose to provide soft water which doesn’t necessarily have anything to do with home water filtration.

Flow Rates

A whole house filtration system has to provide enough filtered water for your kitchen, bathroom(s), dishwasher, washing machine, and all other household appliances that use water.

Therefore, high flow is mandatory if you don’t want to experience a water pressure drop when opening multiple outlets. 10 – 15 gpm is pretty standard for a whole house water filter. Less might not suffice for a large household.

On a side note: A bathroom faucet uses up to 1.5, a kitchen faucet up to 2.2 gallons per minute. The maximum water flow for a shower head usually doesn’t exceed 2.5 gpm.

Micron Ratings

When dealing with suspended solids, filtration effectiveness is measured in micron (one micron is a thousandth of a millimeter). Generally speaking, a smaller micron rating indicates more thorough filtration with more contaminants removed.

For example: Whole house water filters that only remove sand, silt, and rust might have a micron rating of 50. This means they trap the vast majority of particles with a minimum size of 50 microns, which won’t affect contaminants such as fluoride, lead, chemicals, and most pathogens like bacteria.

Other micron ratings are 25, 10, 5, and 1, followed by the sub-micron level. The dilemma: The smaller the micron rating, the lower the output water pressure and flow. This is also why whole house reverse osmosis water systems are super rare. Regular reverse osmosis water purification membranes are rated at 0.0001 micron which is great for TDS (Total Dissolved Solids) reduction. However, the process also reduces water pressure to a trickle if no additional booster pump is applied.

Whole House Water Filter Cost

You should not only take into account the initial purchase price of a whole house water filter, but also the lifespan and cost of replacement filter media/cartridges.

A system featuring a large media tank might cost much more upfront, but likely filters up to 1,000,000 gallons of water or more. This not only means virtually no maintenance requirements for several years, you also save tons of money in the long run.

Cartridge-based home water filters are cheaper in the beginning. Therefore, you need to replace filters every 6 months or so, so that replacement cost start to add up over time.

Space

Whole house water filtration systems are way bigger than the average point-of-use filter. Don’t underestimate their size and make sure you have enough space for installation and maintenance.

More on Whole House Water Filter Systems

What is a Whole House Water Filter?

Opposed to point-of-use units, whole house filters filter water at the point of entry, so all incoming water in your home before it gets distributed. This way you have access to filtered water at every outlet including water-using appliances.

Whole house water filters are also known as point-of-entry water filtration systems.

Why Do You Need a Whole House Water Filter?

If you look at the data, almost all US water supplies are contaminated. Not all of the contaminants are harmful, but many are. So the number one reason why you may need a whole house water filter is to protect the health of your family. And the purified water will taste and smell much better, too!

What if I drink nothing but bottled water? Well, what about the water you use for cooking and showering? For example, did you know that the largest chunk of your daily chlorine exposure does not come from the water you drink but from the water you use for washing? That’s because human skin is permeable for all kinds of stuff. Plus, you inhale some of the volatile compounds. Also, a lot of the bottled water on the market is plain tap water.

The second reason to use a whole house water filter is to prevent your plumbing system, fixtures, and appliances from taking damage due to water containing high levels of iron or sediments for example. This will result in reduced maintenance, fewer repairs, and ultimately safe you a lot of money.

How Does a Whole House Water Filter Work?

Whole house filtration systems connect to the main water line and filter all the water entering your home. How each individual system works depends on what type of filter process it applies:

  • Whole house sediment filters work by size exclusion.
  • Activated and catalytic carbon filters contaminants through adsorption into its surface pores.
  • KDF uses oxidation and reduction to remove chlorine, heavy metals, and certain inorganic contaminants from your water.
  • Bone char relies on adsorption and chemical reactions to remove fluoride and heavy metals from water.
  • Greensand oxidizes and then traps iron, manganese, and hydrogen sulfide.
  • Air injection oxidizes iron and manganese, and sulfur which are then trapped by subsequent filter stages.

What’s more, many systems come with various pre- and post-filters for additional contaminant removal.

How to Install & Maintain Whole House Water Filter Systems?

Installation

plumbing wrenches

Installing a whole house filter system is certainly more difficult than setting up a POU unit. For one, it may involve plumbing. But it’s still doable if you’re handy around the house and have the necessary supplies and tools including tubing, fittings, and a pipe cutter.

In our opinion, getting everything up and running is moderately difficult. Here’s a brief overview of what you need to do if you don’t want to call a plumber:

  1. Follow manufacturer instructions to properly activate any filtration media.
  2. Shut off the main water supply.
  3. Drain any remaining water.
  4. Cut into the main water line.
  5. Optional: Install shut-off valves on both sides of the system for ease of maintenance. Adding a bypass valve is usually not necessary. Most whole house water filters have one already built in.
  6. Connect the whole house filter making sure it’s facing in the right direction. Use Teflon tape on all threads for sealing and adapters on ports if necessary.
  7. Turn the water back on.
  8. Open all valves except for the bypass.
  9. Leaks? Use more Teflon tape.
  10. Flush the entire water system for several minutes.

Maintenance

Whole house water filter systems using a large media tank don’t require maintenance at all. Only the sediment pre-filter needs regular replacement in case there is one.

As for cartridge-based filters, they do require some attention every now and then to perform at their best. Timely filter replacements usually do the trick:

  1. Turn off the water supply.
  2. Drain all remaining water.
  3. Remove the first filter housing, take out the old filter, and insert the new.
  4. Optional: Clean the filter housing with soapy water or bleach solution and rinse thoroughly when done. Lubricate/replace O-rings.
  5. Screw the filter housing back on.
  6. Slowly turn the water supply back on.
  7. Leaks?
  8. Flush the new filters as per manufacturer instructions.

How often should a whole house water filter be replaced? It depends. Is your water full of sediments? Apart from that, one filter might be designed to only last 3 months, while another is good for a whole year.

Frequently Asked Questions (FAQ)

  • Does a whole house water filter reduce water pressure?
    Yes, it does. However, not all whole house filters affect outgoing water pressure equally. Thorough sediment filtration usually results in a higher pressure drop, whereas a whole home water filter based on activated carbon has much less of an effect.
  • How much does it cost to install a whole house water filtration system?
    That’s hard to predict as it depends on the exact system as well as your plumbing setup. We would think the bare minimum is somewhere between $300-500 USD. That said, if you feel comfortable cutting into your main water supply line you might be able to complete the project yourself.
  • How do I choose a whole house water filter?
    That’s exactly the question we tried to answer in our buying guide above. There are a bunch of factors to consider such as the quality of your water source, your filtered water demand at times of peak consumption, and your budget. But it all starts with water testing.
  • Can I drink the water filtered provided by a whole house filtration system?
    Yes, you can. But there’s no guarantee that it’s 100% free from harmful contaminants. That’s why we recommend you do thorough testing before purchasing a system. After all, a whole house water filter must be suited for your specific water conditions.
  • Are whole house water filters worth it?
    Yes, a whole house system is definitely worth it. With the right filter you not only get clean and great tasting drinking water in your entire home. It’ll also protect your home appliances from harm – think sediments.
  • How long does a whole house water filter last?
    This completely depends on the type of system. For example, the SpringWell WS uses greensand media which is backwashed on a regular basis. This allows for an average filtration capacity of 18-25 years. In contrast, regular activated carbon filters may only last one year.
  • Where should a whole house water filter be installed?
    You are free to install your whole house water filtration system wherever you want (as long as no freezing temperatures occur), but it needs access to the main water supply. The garage or basement is usually the preferred location. By the way, make sure to install your system after the pressure tank.
  • How do you maintain a whole house water filter?
    That’s simple. Most units are fully automated and do everything themselves. This includes tasks like backwashing. Filter cartridges need to be replaced on a regular basis, though. Check the product manual for further instructions.
