The Tier1 EPM-20 is a 20-micron carbon-impregnated cellulose filter designed to reduce chlorine taste and odor, along with sediment, rust, dirt, and silt from your home's entire water supply. This dual-purpose filtration makes it an ideal comparable replacement for the Pentek EPM-20, providing both sediment and chemical reduction in a single cartridge.

The Tier1 EPM-20 has a filtration life of approximately 3 months or up to 20,000 gallons, whichever comes first. Actual filter life may vary depending on your incoming water quality, sediment levels, and household water usage. For homes with higher sediment or heavy chlorine levels, more frequent replacement may be necessary to maintain optimal flow rate and filtration performance.

The Tier1 EPM-20 is engineered as a direct comparable replacement for the Pentek EPM-20 and fits standard 9-3/4" x 2-7/8" Big Blue-style whole house filter housings. It is compatible with Pentek #20BB, Pentair, and other industry-standard 10-inch slim-line housings, making it a versatile choice for point-of-entry filtration systems throughout your home.

The EPM-20 uses activated carbon blended into a cellulose matrix to effectively reduce chlorine taste and odor while simultaneously filtering out sediment, sand, silt, rust particles, and scale. This combination filter is ideal for municipal water supplies where chlorine reduction is a priority, delivering cleaner, better-tasting water to every faucet, shower, and appliance in your home.

To install the EPM-20, first shut off the main water supply and relieve pressure by opening a downstream faucet. Unscrew the filter housing sump, remove the old cartridge, and rinse the housing. Insert the new Tier1 EPM-20 cartridge, ensuring it seats properly on the bottom standpipe, then replace the sump and hand-tighten. Slowly turn the water back on and flush the system for 5-10 minutes to remove any loose carbon fines before regular use.
