Hydrotools Replacement Filter Cartridges

Replacement Cartridges

We offer all of the popular filter replacement cartridges for pool and spa filters.  Our pool and spa cartridges are made with 100% Reemay, a spunbonded polyester filtration media that was made specifically for durability and antimicrobial protection.

All our replacement cartridges are compatible for your systems.

Pool and spa cartridges should be replaced every 1-2 years.  Signs that you need to replace your cartridge are a high PSI, cracked end caps, flattening of pleats, frayed fabric or reduction of water flow.
