Product overview
This filter cartridge is a compatible replacement for the Maytronics original, supplied as the Cartridge Filter Door Assembly for M400, M500, M4, M5 and Liberty Pool Cleaners. In service it traps suspended particles as water passes through the pleated media. This is a consumable in practice: the pleats collapse and the media loses porosity, so pressure climbs and cycles between cleanings get shorter. Ours is built with reinforced polyester media.
