The Hayward W3DE4820 Pro-Grid 48 sq. ft. D.E. Pool Filter delivers top-tier filtration, capable of removing particles as small as 5 microns, the size of a red blood cell. It uses 7 full and 1 partial 24" grids coated in pool-grade diatomaceous earth, housed in a durable glass-reinforced thermoplastic tank. A manual air relief valve prevents air buildup in the tank.
The filter features a 1-1/2" drain for fast drainage and a one-piece flange clamp for secure assembly. It requires 58.1" of vertical clearance for removal, and backwashing is recommended before disassembly.
ProGrid filters ensure excellent water clarity, efficient flow, and large cleaning capacity, offering a user-friendly design for pools and spas of all sizes.

*Sizing Note: The gallon capacities listings are estimates only. They will vary depending on the pump size and the turnover rate. The actual number of gallons your filter can manage depends on your pump’s flow rate and the specific needs of your pool (debris load, drains, usage, etc.). You can adjust these capacities if you plan for a different turnover time (e.g., 12-hour turnover).
