3-Stage Under the Sink Water Filter System
Meet The Most Powerful Under-Sink Water Filtration System On The Planet
Worried about your tap water? Typical sink filtration systems either remove too few contaminants, leaving you vulnerable to illness, disease, and other dangers pouring from your faucet… or strip water of beneficial minerals and nutrients. Not only does our advanced under-sink filtration system remove 232+ contaminants including heavy metals, pollutants, and chemicals, it recognizes beneficial minerals and nutrients and intentionally allows them to remain in your water. Upgrade to Clearly Filtered today to enjoy clean water from any existing faucet—no plumber, tank, or extra faucet required.
What Sets Our Under-Sink Water Filter System Apart
- Removes 232+ contaminants. That’s more than most Reverse Osmosis (RO) systems.
- Targets fluoride and lead with our proprietary technology.
- Compatible with any sink. Connects directly to your cold water line.
- Easy installation process. Do it yourself in 15 minutes or less.
- Portable, space-saving design built for homeowners and renters alike.
- No remineralization needed. Intelligent technology allows beneficial minerals and nutrients to pass through.
- Minimizes waste. 75% more efficient than typical RO systems.
- 2000-gallon filter life. Most customers change the filters just once a year.
- Minimal maintenance. Twist-on, twist-off replacement filter cartridges.
- Proven to perform. Tested by third-party labs.
- Built in the USA with high-quality filters.
No plumber or power tools required. All you need is a wrench.
The system can be mounted horizontally, vertically, or simply leaned up against the wall. Filter performance is not dependent on placement or orientation.
The system sits flush and is just 3’’ deep. It doesn’t command any countertop space nor require excess space underneath your sink. Plus, no separate tank, drum, or extra faucet is needed.
Connects directly to your cold water line, no matter the material. Can be used with any sink (kitchen sink, bathroom sink, etc.) or a dedicated faucet to provide clean water for drinking, cooking, cleaning, and more.
Unlike typical Reverse Osmosis systems, our advanced under-sink system ensures there is never any excess wastewater, tasteless “dead” water, or the need to remineralize drinking water after filtration.
Filters are powered by a smarter, stronger, and more efficient filtration technology that recognizes what should stay and what should go.
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.
Each filter has a leak-proof head and built-in water shut-off valve so there’s never any mess during filter changes.
Independently tested to NSF / ANSI and EPA standards by accredited labs to guarantee unparalleled protection. We publish performance data publicly so you never wonder what’s in your water.
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.
Every system includes three replaceable filters developed with our advanced Affinity Filtration Technology. Each of the three filter cartridges serves a unique purpose as they work together to give you easy access to clean water from any faucet.
This sophisticated coconut carbon pre-filter minimizes sediment and particles with various micron sizes to prime water for advanced filtration in Stages 2 and 3. The hazards extracted here impact color, odor, and water tastes, so you can see, smell, and experience the difference.
Built to eliminate hidden heavy metals, herbicides, pesticides, and more, this advanced filter removes the covert chemicals and contaminants that most miss including lead, radiation, chromium, and PFAS.
The breakthrough technology inside this filter removes superior levels of fluoride without relying on typical Reverse Osmosis technology that blindly removes beneficial minerals and produces excess wastewater.
Love my under sink filter system! It was super easy to install and I love the taste of the water, super clean! I was prepared for the reduced water pressure, but I can barely tell...
Took my husband about 5 minutes to install the filter. Love knowing my tap water is safe to drink and washing veggies and fruit using pure water is very comforting. No more chlorine smell! Already had the pitcher and now the under the counter filter system. Thank you!
I have used the under sink filter for a couple of years now and the filters have performed flawlessly. I am now on my second set of filters with no plan of ever buying anything but these filters. Clearly Filtered has changed the game when it comes to providing clean drinking water. I love knowing that the water I am drinking is safe and only contains the things my body needs.
The under sink unit arrived today and installation was straightforward and simple. It doesn't take up much space and the water tastes even a bit better than the CF pitcher which is excellent already. Water flow is decreased a small amount as you describe, but any filter system will do that. It's great running it through the existing tap without having to install a separate spigot and call a plumber, and changing the filters in a year will be a breeze. Glad to be on the VIP program as well. Thanks for a well-thought-out and well-designed product. Keep up the good work.

Love our under counter filtration system. Unfortunately the water main to our house broke this winter and the only way we could drink or cook with water (when we turned on the water valve) was by using the ClearlyFiltered system that we installed last Spring during our kitchen renovation. The water using the filter was crystal clear. We then needed to replace our hot water heaters due to build up, so went ahead and replaced the under sink filters early. It also makes the best, smooth coffee
So far we are loving this system. You can definitely taste the difference in the water. We have well water and there is an iron taste to it. After installing the system the water taste much cleaner. It took about 15 minutes to install with no problems. My husband is now thinking of getting one for his business. So far so good!
This water filter had drastically changed the flavor of my water for the better. I got the filter to improve the water for my family overall, but have not had it tested. Even without testing I can tell the water is improved. I will continue to buy this filter.
Love Love Love it
Had a plumber install to dedicated faucet. Best tasting water, no after taste and great flow ! Hands down the best !

Here is a typical replacement schedule:
4+ people: Replace filters every 9 months
3-4 people: Replace filters every 12 months.
1-2 people: Replace filters every 15 months.
To make upkeep as easy as possible, all three filters have the same lifespan. Therefore, they are installed and changed together. Simply twist off the old filters, then twist on the new filters.

It is compatible with standard water lines; the majority of which are ⅜-inch stainless-steel, and the lightweight system is just 6.9 pounds.
*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.
