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.

I just finally installed the 3-stage system on 1/15. It was a sanp to install. The water tastes great and I no longer have to deal with the cartridges and water pitchers I have been using for yesrs.
This is our 2nd year with the ClearlyFiltered Under-sink filters and we couldn't be happier. The cartridges are super easy to install and have given us excellent tasting water and didn't limit the flowrate substantially. LOVE it for the ease of filling our Hydro flasks and water for meals.
It took a bit longer than expected to get the first "clear" water but once the air bubbles worked their way out the system has been perfect! Easy installation and set up. Much better quality and better taste than previous under sink filtration systems I have purchased.
The water is the most clean, pure water I have ever had. I have used several other filter systems and this one is the best. I set it up with a T splitter and installed a separate spigot in order not to waste. The flow is fantastic. I am very happy and look forward to giving up bottled water.
I had a family member install it and it was simple. Our water has greatly improved and our tea kettle no longer has a build up where I have to soak it in vinegar every other day. We love the taste! Great investment.
After taking the system out of the box, the first thing you will need to do is look under your sink and turn off the cold water valve. Simply turn the valve clockwise to turn it off. Double check that it’s off by trying to turn the cold water on at the faucet. Note that the hot water will still be working.
There may be a little residual water left in the line so before starting the next step place a towel below the cold water valve. Use one of the wrenches to unscrew the cold water line from where it connects to the cold water valve. The UTS system has two lines with a different fitting on each side. For this step, take the line with the female fitting, attach it to the cold water valve, and tighten with a wrench.
Now, take the line with the male fitting and attach it to the line coming from the faucet. Again, use a wrench to tighten it, but this time you may need two wrenches to keep the nut from slipping.
It isn’t necessary to mount the system—it will work perfectly just standing on its own—but if you’re short on space under your sink, mounting it can help you save quite a bit of space. First, place the system against the wall where you are going to mount it. Use a pen or pencil to mark the eyelets so you’ll know where to drill the screw into the wall. Be sure to leave enough room below the filters to replace them when the time comes.
Next, set the system down and drill a screw into each of the two marks you made. Then, use the eyelets on the system to hang it on the screws. Secure it by sliding it to the left or right.
Finally, turn the cold water valve back on by turning it counter-clockwise. That’s it! Now just sit back and enjoy the peace of mind knowing you are drinking clean and safe water directly from your faucet.

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!
- Fluoride: removed at a rate of 99.5%. 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 99.9%.
- 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 99.9%.
- 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%.
