Better Water Everywhere
Pentair's OMNIFilter TO8 cartridges provide better water for your whole house, extending the life of your water heater, dishwasher, and other appliances. They even help improve the taste.


Why carbon?
- Carbon filters excel at reducing contaminants that threaten our health or cause bad tastes and odors. Their vast surface area provides a large capacity for removing unwanted contaminants.
- How it works: As water passes through activated carbon, contaminants become trapped in the pores of its surface area. The surface area of 5 grams of activated carbon equals the surface area of a football field!
