OMNIFilter TO8 Carbon Water Filter 10x4.5-inch, 25 Micron, 40,000 Gallons

Overview

Meet the Pentair OMNIFilter TO8 Carbon Water Filter, a heavy-duty 10-inch granular activated carbon cartridge designed for whole-house filtration. With a 25 micron rating, it targets chlorine taste and odor while catching sand, dirt, sediment, and rust particles to deliver cleaner-tasting water from every tap. Capable of up to 40,000 gallons, this cartridge fits standard 10" x 4.5" housings and a range of OMNIFilter and other brand housings, offering versatile replacement options for many homes.

Designed for steady performance, the TO8 uses a granular activated carbon media with a radial flow design that supports a high flow rate and a lower pressure drop. This combination helps maintain water pressure while filtration takes place, making it suitable for households that rely on consistent flow across multiple fixtures.

How it works

Granular activated carbon (GAC) uses a radial flow design that promotes even filtration and helps sustain water pressure as water passes through the media, delivering taste and odor reduction alongside particulate removal.

Usage tips and care

• Replace every 3 months or when you notice a drop in water pressure
• Monitor taste, odor and clarity to gauge the right replacement timing

What to expect in daily use

Install this cartridge in compatible housings and enjoy cleaner tasting water from every faucet, shower, and appliance connected to your home supply. While results depend on your source water, many households notice a more neutral taste and improved clarity as the cartridge captures a large portion of particulate matter and chlorine byproducts.
