Hayward ProGrid® D.E. Pool Filter DE4820 – Premium In-Ground Pool Filtration
Filter Size: 48 Sq. Ft.
Dimensions: 24.6" W × 23.1" D × 41.8" H
The Hayward ProGrid® D.E. Pool Filter DE4820 delivers exceptional water clarity with the superior filtration performance of diatomaceous earth (D.E.) technology. Designed for residential in-ground swimming pools, the DE4820 captures particles as small as 3–5 microns, producing sparkling, crystal-clear water while maintaining excellent hydraulic efficiency and extended cleaning cycles. Its durable PermaGlass XL™ filter tank provides outstanding corrosion resistance and long-lasting performance in even the most demanding pool environments.
Engineered with Hayward's advanced vertical grid design, the ProGrid® maximizes filtration area while reducing flow resistance for improved system efficiency. The precision-molded filter tank, durable polypropylene grid elements, and tamper-proof one-piece flange clamp make servicing quick and straightforward. A built-in automatic air relief system and manual air relief valve help maintain proper filtration performance while simplifying startup and maintenance.
Rated for 96 GPM with a 48-square-foot filtration area, the DE4820 is an excellent choice for small to medium-sized residential pools seeking professional-grade filtration performance. Its high dirt-holding capacity extends the time between cleanings while delivering consistently clear water throughout the swimming season.
