4 Things to Know About DE vs. Sand Pool Filters

DE filters catch smaller particles They trap debris down to 2-5 microns, while sand filters stop at 20-40 microns. This gives noticeably clearer water if you’re picky or have fine debris.

DE filters require more maintenance You must backwash regularly and add fresh DE powder each time. The grids can tear, and disposing of DE is environmentally messy.

Sand filters are simpler and cheaper Backwash every few weeks and replace the sand every 5-7 years. They cost less upfront and are easier to fix, though water is slightly cloudier.

Most homeowners won’t notice the difference Sand filters still produce perfectly swimmable water. Choose DE only if you obsess over clarity and don’t mind extra work.
