Buying Guide

Filter Type Compatibility

Before buying a cleaner, confirm it works with your filter type. Most products listed here are safe for cartridge, sand, and DE filters. For example, the AquaDoc Hot Tub & Pool Filter Cleaner Soak is labeled for all three types. If you have a spa or hot tub, choose a product specifically designed for those systems to avoid damaging delicate cartridges.

For above ground pools, see our Above Ground Pool Cleaners guide for compatible equipment.

Application Method

Cleaners come as soak solutions, sprays, or concentrates. Soak products like the AquaDoc and Tillbrook concentrate require you to submerge the filter for an hour or more. Spray options like Black Diamond Stoneworks work in minutes, perfect for quick maintenance. Consider your schedule and how dirty your filter gets.

Cleaning Tools vs. Chemicals

Sometimes a good cleaning tool is all you need. The Aqua Comb Pool Filter Cartridge Cleaning Tool uses high-pressure water to blast debris from pleats. For heavy buildup, combine a tool with a chemical cleaner. The CYCLONE FILTER CLEANER spins your filter while you spray, making the job faster.
