Bostome 525 Sq Ft Cartridge Pool Filter – Leak-Proof Inground System

Murky water, constant back-washing, and weekend-wasting filter fixes feel like part of pool ownership—until they don’t.

Picture water so clear you count the tiles from the patio, maintenance that takes minutes, not hours, and a system that quietly protects swimmers and equipment season after season.

Meet the Bostome 525 Cartridge Pool filter, the Proof Inground upgrade that turns frustration into freedom. Its 525 sq ft pleated core traps particles down to 50 microns with lead-free paper, while the one-piece, fiberglass-reinforced housing eliminates leak points and withstands weather extremes. A built-in pressure gauge and automatic relief valve keep operation safe and predictable, and the 2-inch ports flow with pumps 2.2–3 kW for pools up to 204 m³. When cleaning is due, lift the lid, rinse the four reusable cartridges, and restart—no tools, no plumbing detours.

Install in three simple connections, set your timer, and reclaim your weekends. Add the Bostome 525 to cart now and swim in professionally filtered water without the professional headaches.
