5 Things to Know About DE vs. Sand Pool Filters

DE filters catch smaller particles They filter down to 2-5 microns, while sand filters stop at 20-40 microns. This gives noticeably clearer water.

Sand filters are simpler to maintain You backwash every few weeks and replace the sand every 5-7 years. They are forgiving, cheap to run, and good enough for most pools.

DE filters require more work After backwashing, you must add fresh DE powder. The grids clog over time and need periodic hose cleaning, sometimes chemical cleaning.

DE parts wear out faster and cost more Components need replacement more often, and some areas regulate disposal of the DE powder.

Choose based on your priority for clarity If you want resort-pool sparkle and don’t mind chores, go DE. If you prefer less filter maintenance, stick with sand—the water will be safe and swimmable, just not as clear.
