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. Our advanced under-sink filtration system removes 232+ contaminants including heavy metals, pollutants, and chemicals. 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.
- Intelligent technology does not target beneficial minerals and allows them 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.

Easy to install and very convenient when getting water. I’ve had your container filter for years, but this one is a game changer!
We had been using two pitchers to keep up with our water demand. Switching to the under sink version is so much better! Installation was simple and quick so we had filtered water coming out of the faucet in just minutes! As much as I loved the pitchers, I do love having my counter space back and the convenience of filling right from the faucet. My property has been inundated with hummingbirds since they lost their habitat to forest fires. 260,000+ acres near me and it has not recovered yet. I fill 15 hummingbird feeders 2-3 times per day to keep up with their demand (not to mention all of the Orioles) and it has been SO MUCH EASIER to use water from the faucet now. The birds much appreciate it, too! So Clearly Filtered is helping the hummingbirds and Orioles too : )
The replacement filters were so easy to install. Took a while before my water pressure was back, but overall worth it.
I can finally stop worrying if I have enough bottled water!
I have a very rare and annoying Flouride filter, so having water without Flouride is not a choice for me. The inside of my mouth/throat gets sores and the skin literally flakes away. I did not know there was a compact filter available that could remove this substance, plus make the water taste great (I’m a water snob after drinking just bottled water for years). This ticks both boxes, and I no longer freak out when I’ve poured the last bit of my last gallon into the coffee maker. Truly a godsend. Thank you!
Install was very easy, less than 5 minutes. Noticeable different in the taste of the water. Lives up to my expectations.

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.
