Pool Filter Cartridges

Pool filter cartridges capture dirt, debris, and fine particles as water circulates through the filtration system. Replacing cartridges regularly helps maintain proper filtration and clear water. Browse our pool filter cartridges to keep your pool filter operating efficiently.

Crystal-Clear Water Starts with Quality Filter Cartridges

A clean, safe, and inviting pool depends on effective filtration—and at the core of many filtration systems are filter cartridges. Unlike sand or D.E. filters, cartridge filters use pleated material to capture dirt, oils, pollen, and debris as water passes through. They deliver superior water clarity, require less backwashing, and are easier to maintain.

At Benchmark Pool Supply, we offer a wide selection of pool and spa filter cartridges from trusted brands like Unicel® and Pleatco®. Whether you need a replacement cartridge for a single filter housing or a full set for larger systems, our collection provides durable, high-performance options for every pool and spa.

Pair filter cartridges with Unicel Filters , Pool Filters , and Filter Parts for complete water clarity.
