Pentair Quad DE 100 Sq Ft Cartridge Pool Filter | EC-188594

Pentair Quad DE 100 Cartridge Style Pool Filter | EC-188594

The Pentair Quad DE 100 EC-188594 Cartridge Style Filter offers the perfect balance of diatomaceous earth (DE) filtration clarity and cartridge-style convenience. With 100 sq. ft. of filter area, this system is engineered for large residential pools and spas, delivering outstanding water clarity with reduced maintenance requirements. By using four cartridge-style DE elements, it combines the fine particle filtration of DE with the easy cleaning process of a cartridge filter.

This hybrid design eliminates the need for messy backwashing. Instead, pool owners can simply remove the cartridges, hose them off, and reinstall—saving water, reducing service time, and lowering overall maintenance costs. The EC-188594 is constructed with a fiberglass-reinforced polypropylene tank that resists corrosion and harsh environmental conditions. A heavy-duty clamp ring provides tool-free access for servicing, while hydraulic-efficient engineering ensures reliable circulation and system performance.

Trusted by pool owners and professionals alike, the Pentair Quad DE 100 is an advanced filtration system that provides superior clarity, durable construction, and easy-to-manage maintenance for long-term pool care.
