I love it!
Ahhh! Great tasting water again! Thank you Omnifilter! This works fantastic! I highly recommend getting this! The installation wasn't too bad, but a YouTube video from the company would have been nice. This is my second unit, my first one lasted 15 years!

Perfect Balance
If you're looking for a water filtration system that tastes great and takes up very little room under your sink, then I recommend giving this a try.

Under Sink Frequently Asked Questions
-
What is the difference between undersink and countertop systems and whole home systems?
-
Undersink and countertop systems are filtration systems that reduce chemical contaminants and sediment from the faucet where it is installed (point-of-use) whereas a whole home filtration system does the same thing at the point where the water enters the home (point-of-entry), resulting in a higher quality of water throughout the entire home. Undersink and countertop systems are more cost-effective ways to improve your water at individual faucets.
-
Do under sink filtration systems come with everything I need to install?
-
Yes, your Pentair under sink filtration system is equipped with everything you need to successfully install your system (excluding tools). In your manual you will find a list of all components that are included, and a list of additional tools/items needed to help with the installation
-
How much space is required for this system to fit underneath my sink?
-
You will need approximately 18” depth x 6” width x 17.5” height of space underneath your sink for most under sink filtration systems to fit. Please confirm with the product manual for exact specs.
-
What if my countertop doesn’t currently have a hole for the faucet?
-
Don’t have an existing side faucet? No problem! Check our product manuals for instructions to create the faucet hole in your countertop.
-
What do I need to install the faucet?
-
You will need masking tape, a center punch, a ¼” drill bit , a 1-1/4” hole saw, and a file to install your under sink filtration system. Confirm with the product manual for exact requirements.
