Built by Pentair, this 48DE Diatomaceous Earth Pool Filter 180008 High-Clarity is a trusted pick for pool owners and service pros alike.

The Pentair 48DE Diatomaceous Earth Pool Filter (180008) provides exceptional water clarity by using diatomaceous earth (DE) to trap particles as small as 2–3 microns—far finer than sand or cartridge filters. Designed for residential pool systems that demand top-tier filtration, this DE filter delivers smooth, efficient flow with minimal pressure rise and extended cycles between cleanings.

Built with rugged materials and engineered for long-term durability, the 48DE reduces maintenance and helps ensure crystal-clear water. Its easy-access tank and simple backwash operation make servicing quick and straightforward, while the premium internal components support consistent performance season after season.
