Best Drinking Water Filter Reviews

1. Our Number One Drinking Water Filter Pitcher: Clearly Filtered

Water filter pitchers are small enough to be carried around and stored in the refrigerator for cooling, they’re handy, and they’re affordable. What’s more, they’re installation-free and can be assembled in a matter of minutes. All this makes water filter pitchers the most popular type of home drinking water filters money can buy.

In our opinion, the best drinking water filter as far as pitchers are concerned is the Clearly Filtered. It removes more water contaminants than any other model on the market and it’s suited for both tap water and disinfected well water. Filtered water taste? One word: Superb.

Bottom line: The Clearly Filtered is our go-to water filter pitcher. 5 stars!

Pitcher Alternative: Aquagear

We wanted to provide you with one water filter pitcher alternative in case you don’t like the Clearly Filtered for whatever reason.

Our number two is the Aquagear. It hasn’t been tested nowhere near as thoroughly as the Clearly Filtered, however, it’s still one of the best units out there removing fluoride (98.6%), volatile organic compounds, lead (99.9%) and other heavy metals, nitrate (97.6%), TTHMs (99.0%), and more. NSF testing standards 42 + 53 are met.

Another feature to point out is the long-lasting replacement filters. 150 gallons of water should last you up to 6 months. And they, too, are made in the USA. The pitcher itself is warranted for lifetime.

Disadvantages? Not exactly cheap compared to some of the most popular water filter pitchers. Also, filtration can be slow.

2. Our Favorite Reverse Osmosis Drinking Water System: Aquatru

Reverse osmosis filtration removes almost all water impurities. Plus, RO systems provide enough water for an entire family and they’re cost effective.

When it comes to reverse osmosis drinking water systems in 2020 the AquaTru is our first choice. That’s because it has earned NSF certifications for the removal of more than 80 different contaminants commonly found in our water supplies. That’s better than any other RO system we know of, and guarantees healthy, safe, and great tasting drinking water for you and your family.

But what we love most about the AquaTru is the fact that it’s a countertop unit which doesn’t require installation. The plug ‘n’ play functionality allows you to set up and use the system right away without any drilling, drain line connection, etc. – perfect for renters and to save money. 4.5 stars.

    • Pump also greatly reduces wastewater production. Only 20% of the input water goes down the drain. Regular reverse osmosis systems waste 3 to 5 gallons of water for every gallon of filtered water.
  • AquaTru RO drinking water filter system can be set up within a few minutes.
  • Maintenance is child’s play. Filters are long-lasting and can be replaced with a simple turn. The system will tell you when.
    • Most users have to replace annually/biannually. Cost: Around $100-120 per year on average which is affordable compared to the competition.
  • All plastic is BPA and BPS-free.
  • 1 year warranty.

Cons

  • Some units leak due to design flaw.
  • A few people complained about malfunctioning systems.
  • Reverse osmosis strips away healthy minerals.
    • Solution: Use mineral salt/blend or remineralization stage.

4. Reverse Osmosis System for Well Water (Optional UV): Crystal Quest 1000C & 1000CP

If you like reverse osmosis but you’re on well water and have no pre-treatment in place expect for disinfection, your best choice is the Crystal Quest 1000C or the 1000CP (the 1000CP comes with a pressure pump).

Both systems will take care of the vast majority of contaminants found in well water and make it ready for drinking. By the way, you can add a UV light stage for 99.99% reduction of microorganisms.

Please note: According to Crystal Quest, up to 15 grains per gallon water hardness can be handled. Iron shouldn’t exceed 2 ppm. Higher levels may lead to clogging.

Pros

  • 12 stages of filtration remove sediment, taste & odor, volatile organic compounds, chlorine, chemicals, and most importantly for well water iron and other metals, hydrogen sulfide a.k.a. rotten egg smell, hardness minerals, herbicides, pesticides, industrial solvents.
    • Stage 1 is an activated carbon block.
    • Next comes an ultrafiltration membrane for the reduction of microorganisms and other organic/inorganic molecules.
    • Filter stage 4 uses granular activated carbon media which removes chlorine, all kinds of chemicals, and bad taste and odor.
    • At stage 5, an ion exchange resin reduces water hardness and also traps heavy metals like lead.
    • For the following 2 filter stages, water gets in contact with a copper-zinc blend. The media adsorbs some contaminants while rendering others harmless. Also prevents bacteria from growing inside the RO system.
    • At the heart of the system lies the reverse osmosis membrane, rejecting all particulates larger than 0.0001 microns.
    • Filter stage 11 is another granular activated carbon filter which takes care of residual tastes.
    • All other stages are plain filter pads (1 micron).
  • Optional: UV light stage. Kills any bacteria, viruses, and protozoa.
  • Optional: Nitrate filter for wells near agricultural lands and animal feedlots.
  • Optional: Fluoride filter for elevated levels of organic fluoride.
  • About as difficult to install as any other under sink RO systems.
  • Basic maintenance needs. Cost: $100-155 per year which is okay.
  • One year limited warranty.

Cons

  • We’re missing NSF certifications.
  • Seems like installations instructions need more detail.

6. Whole House System Best for Tap Drinking Water: SpringWell CF4

Whole house water filters have the benefit of processing all the incoming water before it’s distributed throughout your home. Thus you have filtered water at every outlet. However, they’re seldom sophisticated enough to be capable of removing a wide range of contaminants.

That said, your best option when on tap water is certainly the SpringWell CF4. Making use of catalytic carbon mixed with KDF as well as a small pre-filter, the system removes sediments, chlorine + chloramine, any disinfection byproducts, VOCs, pesticides, and several heavy metals. In addition, microorganisms have no chance of accumulating in the large tank, leaching into your water.

All in all, your drinking water will be much safe(r) for consumption and, of course, its taste and smell will improve greatly, too. 5 stars!

Buying Guide: Home Drinking Water Filtration

When it comes to home drinking water filtration, there’s no one-size-fits-all solution. With literally hundreds of different contaminants that you could be facing, you need to have your water thoroughly tested if you want to be 100 percent sure to not miss anything. Once you have a list of contaminants present in your water supply you can choose the best treatment method accordingly.

Of course we understand that doing one’s own testing is just not feasible in all cases, for example if you don’t have the budget. In this case, we recommend you take a look at your annual water quality report which your utility has to provide for free. Testing for the report might not show the full picture, but it’s still better than a shot in the dark. You can browse for your report here.

If that isn’t possible either, your best bet is to get a water filter (system) that removes a broad range of pollutants: Heavy metals, VOCs, disinfectants and their byproducts, perfluorinated chemicals, pharmaceuticals, pesticides, herbicides, semi-volatile compounds, radiological elements, and microorganisms (not really necessary when you’re on municipal water). Personally, we would opt for either the Clearly Filtered pitcher or the under sink filter, or the AquaTru countertop RO system. All 3 have been tested for the removal of dozens upon dozens of contaminants with solid results.

tap water

Best Way to Filter Tap/Well Water for Drinking

The following is a list of common tap/well water contaminants and what you can do about them (no claim for completeness):

  • The most common contaminants in municipal drinking water are chlorine/chloramine and their disinfection byproducts. Catalytic carbon is the best filter media for chloramines. For chlorinated waters, activated carbon does the trick. Both activated and catalytic carbon will also eliminate most VOCs.
  • In case there’s lead in your water – the heavy metal was used as a building material for pipes before its ban in 1986 – you should opt for reverse osmosis drinking water purification or activated/catalytic carbon combined with KDF-55.
  • Furthermore, many municipalities add fluoride to their water. Now, water fluoridation is a controversial topic. We leave it up to you to decide if you want to do anything about it. Just know that if you want to remove fluoride from your water you can use reverse osmosis, anion exchange or activated alumina adsorption media, and distillation.
  • Arsenic: More than 100 million Americans received water with arsenic exceeding California’s public health goal between 2015 and 2017 (source). The best treatment option for arsenic is reverse osmosis or ion exchange technologies.
  • Simply put, chromium 6 is everywhere which is really concerning. Preferred filtration technologies are reverse osmosis and iron exchange.
  • PFAS, or per- and polyfluorinated substances, include more than 3,000 synthetic chemicals that can have serious health effects even in low dosages. The Environmental Working Group estimates that “up to 110 million Americans could have PFAS-contaminated drinking water”. What can you do about it? Filter with reverse osmosis and/or carbon.
  • If you have radioactive elements in your water you might need to install a whole house water filter as some of them volatilize from shower or bath water.
  • And lastly: Nitrate. The highest concentrations can be found in tap water or private wells in agricultural areas. RO is the most effective treatment method.

Systems with NSF Testing & Certifications

Manufacturers can make contamination reduction claims about their products all day long. But only NSF or EPA standardized testing and certification provide proof. Thus when you’re shopping for a drinking water filtration system look out for performance data sheets or other lab testing data.

Most important are the following NSF standards: 42, 53, 244, 401, P473, and 58 (RO systems only).

Filtering Speed + Filtered Water Storage Capacity

Depending on the size of your family, a smaller filter might not be able to meet your drinking water demand. The result: Long waiting times. If you want to avoid such a scenario double-check that the product you’re eying filters water fast enough or comes with an adequately-sized storage tank.

Cost: Initial vs Long-Term

Some drinking water filter systems seem surprisingly affordable at first. But they turn out all the more expensive in the long run – think replacement filter cost. Replacement filter capacity and cost is definitely something you should consider.

Installation and Maintenance

All filter systems on this page are quite easy to maintain. Unfortunately, the same cannot be said about their installation. For example: While filter pitchers can be assembled in a matter of minutes, whole house units require proper inlet and outlet connections which may involve plumbing. So if you’re not exactly handy around the house and you’re unwilling to pay a plumber to do the work for you, a whole house water filter might not be ideal.
