3. The Runner-Up: Pelican PC1000 Whole House Water Filter

We wanted to provide you with an alternative for municipal whole house water treatment in case you don’t like the SpringWell CF4 for whatever reason. Thus, let us introduce you to the Pelican PC1000 whole house water filter system. It’s a tad more expensive than the SpringWell CF4, but people who installed it could immediately tell the difference in their water quality: Clean & refreshing taste, odor-free, and more gentle to the skin. All in all, the price is still fair making it an ideal choice for basic filtration needs.

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

In our opinion, the best whole house cartridge water filter for chlorinated city water in 2020 is the NU Aqua 3 Stage Whole House Water Filtration System. Just like the 3 products reviewed above, the NU Aqua provides clean, filtered 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. But even in the realm of whole house cartridge water filters it’s surprisingly cheap, considering all the extra features. Bottom line: 4.5 stars!

5. Our #1 Whole House Cartridge Water Filter for Well Water: Home Master HMF3SdgFeC

In our opinion, the best whole house cartridge water filter for well water in 2020 is the Home Master HMF3SdgFeC. It was specifically designed for chlorine free water supplies with low levels of iron. The promise: Provide an entire home with water freed from bad tastes and odors. Water that doesn’t stain clothes, sinks, and toilets etc., and that doesn’t damage water-using appliances. 4.5 stars!

Annual Cost:$260+
Warranty:2 Years

Our Rating

Pros

  • People are very pleased with their results. They saw an improvement in water quality right after installation – no more iron staining, clean 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 like 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.
  • Filter stage 3 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 gallons per minute which is plenty of water and sufficient for homes with 4+ bathrooms.
  • Not difficult to install if you have any prior plumbing experience or are simply handy with tools.
  • Low in 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 changes.
  • Customer support is impressive. You can send in your well report and get recommendations from the knowledgeable staff members.
  • Two-year limited warranty.

Cons

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

6. Our Number One Sediment Filter: Custom Home Master System

In our opinion, the best whole house sediment filter in 2020 is a custom Home Master system. 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

  • 30-micron and 5-micron sediment filters filter out larger contaminants: Sand, silt, rust and dust.
  • 1-micron sediment 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 customer support.
  • 2-year limited warranty.

Cons

  • No built-in bypass.

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

Last but not least, a whole house water filter for everyone on a tight budget. 3M’s Aqua-Pure AP903 makes your water look, smell, and taste delicious. Since it won’t help to get rid of most smaller contaminants such as heavy metals and pesticides it’s best for people that have fairly clean water already.

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 replace 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 pressure drop.
    • Too expensive to change at such frequency so you may need additional pre-filter(s) to get rid of particles that obstruct the Aqua-Pure AP903 very easily.

Buying Guide: Top Considerations Before You Buy a Whole House Filter

One fact is inevitable: Official reports show that the quality of (drinking) water in the United States is alarming. Day in and day out, the majority of us consumes water contaminated with chemicals from agricultural runoff, traces of pharmaceuticals, heavy metals – think lead – chlorine, fluoride…

Fortunately, it seems like more and more people are becoming aware of the problem and the need to do something about it – and so do you, which is great! But before you go out and buy a water filtering solution for your home, consider this:

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

First of all, you should try to find out more about the quality of water that you receive. This allows you to purchase a whole house water filter capable of dealing with all the contaminants lurking in it.

Are you on well or on municipal 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 test kit which gives you a rough idea of what you are facing (more details on how to filter well water below):

For those lucky ones among us that receive city water, you can go here or here and browse for your utility. All reports in both databases are available for free!

Municipal tap water usually contains lots of disinfection byproducts like trihalomethanes and haloacetic acids that are, for example, associated with an increased risk of bladder cancer.

What’s more, most municipal water is fluoridated. Studies have linked fluoride to harming teeth and bones and also cause bone cancer. The bad news is that only a small number of whole house filters will help to remove fluoride from your water.

Wells are in many cases polluted with chemicals from agricultural runoff. Fertilizers, pesticides, herbicides, disease-causing microorganisms – the list goes on.

There’s also a chance that you water is contaminated with lead, which originates from old pipes. If you are worried about this issue, you might want to check out our article explaining how to best remove lead from water.

Whole House Water Filter Types

More or less all whole house water filters can remove the common contaminants. These are sediments, chlorine and a number of chemicals responsible for creating an unpleasant odor and taste. Those filters specialized in well water treatment will also eliminate iron (rust) and other heavy metals.

But only reverse osmosis filter technology is capable of removing all the bad stuff and make water 100% safe for drinking and cooking. Your water quality report or a lab test will tell you, if you may need one of these.

The downside: Whole house reverse osmosis filter systems can be really expensive. Alternatively, a smaller point-of-use unit that can be installed under your kitchen sink and that provides filtered drinking water for one tap only offers a viable addition to any regular whole house filtration system.

What about installing a water softener? Well, water softener systems soften water. Other than scale, they’re not meant to remove dirt or chemicals etc.

Flow Rates + Micron Ratings

What you need to bear in mind is that a whole house filtration system has to provide enough filtered water not only for the kitchen faucet but also your bathroom(s), the dishwasher, the 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. Anything lower than that 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 gpm. The maximum water flow for a shower head usually doesn’t exceed 2.5 gpm.

At the same time, you want your whole house filter to be effective. In this case, effectiveness is measured in micron. One micron is a thousandth of a millimeter. Generally speaking, a smaller micron rating indicates a more thorough filtration with more contaminants removed.

For example: Whole house water filtration systems that only remove sand, silt and rust might have a micron rating of 50. This means they trap all or most of the particles dissolved in water with a minimum size of 50 microns, which won’t affect contaminants such as fluoride, lead, most 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 systems are rare. Regular RO membranes are rated at 0.0001 micron, which reduces water pressure to a trickle, if no additional booster pumps are applied.

Whole House Water Filter Cost

We are all trying to save. This is why, when it comes to whole house filters, you should not only take into account the initial purchase price of a system, but also filter life and cost. Water filters that have a high capacity (measured in gallons) will last for a longer period of time.

If you want to estimate your water consumption, calculate with 80 – 100 gallons per person and day.

Space

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

How to Best Filter Well Water (for Drinking)

Even though this buying guide is only partly about whole house well water filtration system reviews, we want to provide you with more information on how to properly treat your well using a whole house water filter.

About Whole Home Filtration and Well Water

Well water is groundwater, which means that it comes mainly from rain sinking down through the earth’s soil. This fact explains why well water contains a lot of contaminants. Some of these are natural impurities, take sediments, calcium, magnesium and selenium as an example. Others are manmade contaminants like chemicals entering the water cycle as industrial and agricultural runoff or sewage waste.

Natural or manmade – both groups of contaminants can pose serious health risks. The good news is that if you are supplied with city water, your municipality has already taken care of the majority of dangerous bacteria, cysts, etc. If you rely on a private well, however, this is simply not the case and you are responsible for making sure that your water is safe for your family.

Best Whole House Well Water Treatment System Setup

A residential whole house filtration system for your well should combine a sediment filter stage for larger particles like dirt and rust with a chlorine stage for bacteria.

Additional activated carbon filters remove any amount of chlorine and organic contaminants and neutralizes bad tastes and odors. Need more info on chlorine removal? Click here: best-osmosis-systems.com/how-to-remove-chlorine-from-water/

activated carbon

An iron water filter is a worthy upgrade to remove ferrous iron, ferric iron (rust), manganese and sulfur. Want to know more? Follow the link: best-osmosis-systems.com/water-filters-to-remove-iron/

An additional water softener stage with a salt resin or a separate water softener is best suited to regulate hard water minerals in severe cases.

Instead of a chlorine stage, which could be the source of disinfection byproducts, you can also opt for a UV filter stage. UV filters kill all waterborne pathogens including bacteria and viruses.

Frequently Asked Questions (FAQ)

  • Does a whole house water filter reduce water pressure?
    Yes. More filter stages and a more thorough filtration means higher pressure drop.
  • How often should a whole house water filter be replaced?
    It depends. Is your water full of sediments? Apart from that, one filter might only last 3 months, while another is good for a whole year.
  • Are whole house water filters necessary?
    This depends on the quality of water in your home. If it doesn’t contain any harmful type of contaminants, you’re fine. But this is rare so you might want to consider having it tested.
  • How much does it cost to install a whole house water filtration system?
    Between $100 and $500+. If you feel comfortable cutting into your main water supply you might be able to do the job yourself, by the way.
  • How do I choose a whole house water filter?
    There are a bunch of factors to consider such as the quality of your water, your filtered water demand at times of peak consumption, and your budget.
