Pool filters
Cartridge filters trap fine particles in a pleated element you rinse and eventually replace. They are the low-fuss choice for many pools, especially smaller and above-ground setups.
Water passes through a pleated cartridge that catches debris down to a fine level. There is no backwashing. When flow drops or pressure rises, you pull the cartridge, hose it clean, and reinstall it. Every season or two the element wears out and gets replaced.
Cartridge filtration shines on small to mid-size pools and anyone who wants simple maintenance without a backwash line. It filters finer than sand and wastes no water cleaning, which matters where backwash disposal is restricted. The trade-off is periodic cartridge replacement and more frequent rinsing during heavy use.
Rinse when pressure climbs 8 to 10 psi over your clean baseline, not on a fixed calendar. Soak cartridges periodically to clear oils and fine buildup that a hose misses. Keep a spare so you can swap and clean at leisure rather than leaving the pool unfiltered.
Pool Filters
The lowest-cost, simplest way to filter an above-ground pool: a drop-in cartridge system verified for 4,000 to 15,200 gallons, with no sand to buy or backwash.
