3-Stage Under-the-Sink Water Filter System

The initial set up is a piece of cake. All you’ll need are the instructions, a pencil, two wrenches, the two screws that came with it, and a drill. If you’d prefer to use video instructions, you can find them here.

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.

The Under-the-Sink (UTS) unit 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!

The Under-the-Sink (UTS) unit is both large enough to remove contaminants from large quantities of water and compact enough to fit neatly under your sink. An image with the exact dimensions is below. The fitting on the intake line is female ⅜” compression. The fitting on the output line is male ⅜” compression.

Our filtration technology removes over 230 contaminants. We use an independent, EPA-certified lab to rigorously test our filters to NSF standards. Here are just a few of the more notorious contaminants this filter removes:

• 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%.

We are all about transparency so we post our full test results on our Test Results Page. It shows the name of the particular contaminant, the concentration before filtration, the concentration after filtration, and the percentage removed.
