The Filters

R.O. Quality Filtration—Without The Drawbacks

Filters are powered by a smarter, stronger, and more efficient filtration technology that recognizes what should stay and what should go.

Tool-Free Filter Changes

No need to shut off your water supply or hunt down tools. Replacement filters twist on and off. Plus, all three filters are installed and changed together so you never have to track individual usage.

Built-In Water Shut-Off Valves

Each filter has a leak-proof head and built-in water shut-off valve so there’s never any mess during filter changes.

Rigorously Tested to NSF Standards

Independently tested to NSF / ANSI and EPA standards by accredited labs whenever the standards are applicable to guarantee unparalleled protection. We publish performance data publicly so you never wonder what’s in your water.

Extended 2,000-Gallon Filter Life

Proven to perform better longer, no filter change is needed until approximately 2,000 gallons of water have been filtered. Our high-capacity filters last an average of one year for superior performance with minimal maintenance.

The
R.O Quality Water without the need for a plumber
See Why It's So Good

Unlike typical filter technologies, our breakthrough Affinity Filtration Technology uses 7+ proprietary filtration materials to create multiple stages of filtration that can remove up to 99.9% of 232+ contaminants. This means no need for a plumber, simple easy-twist filter replacement, contaminant removal levels beyond reverse osmosis and no permanent installation. It's a no-brainer!

Stage 1:
Stage 2:
Stage 3:
Stage 1:

Water first passes through a woven, stainless steel mesh screen, which keeps larger particles from entering the filter. Built in the USA.

Stage 2:

Next, water continues through a loose granulated coconut carbon filtration layer, which removes chlorine, bad tastes, and odors. Built in the USA.

Stage 3:

Water then flows through the filter’s composite shell, which is made of 7+ proprietary filtration materials. This dense layer slows down the flow of water and allows for the filter to have more time in contact with the water. The combination of the proprietary breakthrough technology and additional contact time allows for superior removal percentages on all contaminant types. Built in the USA.

Cloudy

After putting in the replacements and running the water for a few minutes, the water comes out cloudy, but later clears up🤷‍♀️. How long before there is no cloudiness?

So Glad We Found Clearly Filtered

Easy replacement installation and presto we have clear, clean water for another year! Everyone comments on how wonderful our water tastes and we drink a ton of it, so the peace of mind it brings is definitely worth it! I have to say that with all of the water issues around the country now, this is the most important money you will spend on your body (which is 50-60% water!). Thanks Clearly Filtered!

Great, easy, convenient!

We love our under sink filters. The convenience of turning on a faucet and having clean water whenever I need without taking up room in our fridge or on the counter (of our small house) is awesome.

Besta Water Ever

Our hard water was awful. We used to buy bottled water for drinking. I would never drink the tap water until we purchased the under the sink water system. May have seemed expensive at first, but not only is the water wonderful, but considering how much we would spend prior to this system, it is certainly cost effective. Not to mention no more plastic, nor waste for the enviroment.

Frequently Asked Questions
How often should I change my filters?
The Under the Sink System (UTS) is built for large quantities of water and will last for up to 2,000 gallons. That milestone is reached at different times according to the number of people using it. Our guidelines are as follows:

Individuals: 15 months
Couples: 12 months
Families: 9 months

All three filters must be changed at the same time. All municipal water supplies are different, so the frequency at which filters need to be changed is always approximate. We recommend making a note of your installation date as a reminder of when to replace the filters or you can sign up for our filter subscription: you’ll never forget to switch your filters and you’ll save 10% on each filter replacement!

*If your tap water is heavily contaminated (most likely if you live in a large or older city), your filter must work harder to keep your water clean, which will decrease the life of the filter.
Which contaminants do the UTS filters target? (e.g., Fluoride, Lead, Chlorine)
Our filtration technology targets over 230 contaminants. We use an independent, EPA-certified lab to rigorously test our filters to all applicable NSF standards. Here are just a few of the more notorious contaminants this filter targets:
  • Fluoride: removed at a rate of 90.7%. It is difficult to remove once it’s added into the tap water and typical carbon-block style filters don’t have fluoride removal capabilities. For that reason we specially formulated our technology so fluoride removal is standard with every filter.
  • Glyphosate: The active ingredient in Roundup® weed killer. Our filters remove >99.9% of this highly controversial chemical.
  • PFOA/PFAS/PFOS: The chemicals that make pans and apparel “non-stick” but are extremely toxic when consumed. Removed at a rate of >99.8%.
  • Lead: Even though it’s been widely banned due to its highly poisonous nature, lead pipes remain in use across all 50 states. Lead is harmful to human health even at low exposure levels and accumulates in the body over time. Removed at a rate of 98.9%.
  • Chlorine: While chlorine is effective at reducing the spread of infectious waterborne diseases, it reacts with naturally-occurring materials in water to form dangerous chemical byproducts that threaten your health. Removed at a rate of >98.6%.
We are all about transparency so we post our full test results on our Test Results Page.
What material are the Under the Sink filters made of?
The Under the Sink (UTS) unit is made with a proprietary blend specifically formulated for Clearly Filtered. These filters are made from a multi-blend of catalysts that target the contaminants commonly found in municipal tap water giving you and your family convenient, clean, and safe drinking water.

*If your tap water is heavily contaminated (most likely if you live in a large or older city), your filter must work harder to keep your water clean, which will decrease the life of the filter.
