Warnings and Disclaimers

Pressure Hazard: Always turn off the pump and bleed all air from the system using the air relief valve before opening the filter canister to prevent serious injury.
Dimension Check: Verify the 2-3/8" hole diameter before installation; a mismatch can lead to unfiltered water bypassing the element.
Chemical Usage: Do not place sanitizing tablets directly inside the filter core; concentrated chemicals will degrade the [PVC center core](https://www.poolsupplyunlimited.com) and polyester media.
Service Only: This cartridge is designed for filtration only; it cannot be backwashed like a sand or DE filter.

Pro Tips

Cleaning Schedule: Clean the cartridge when the tank pressure gauge rises 8-10 PSI above the starting pressure of a brand-new filter.
Effective Rinsing: Use a specialized [filter cleaning wand](https://www.amazon.com) to get deep into the pleats where oils and calcium build up.
Rotation Strategy: Purchase two cartridges and rotate them. Allowing one to dry completely after cleaning helps the polyester fibers "reset" and improves filtration efficiency.
Degreasing: If your pool sees heavy sunblock or lotion use, soak the cartridge in a [degreasing solution](https://www.lowes.com) seasonally to restore water flow.
