DE Pool Filters

Understand DE Pool Filters - Your Swimming Pool Filter System & Swimming Pool Pumps and Filters.

Simply put, diatomaceous earth (DE) are the bones of tiny little animals and plants that lived millions and millions of years ago, diatoms.

DE swimming pool filter systems are the most effective pool filtration available, but on the downside, they also require the highest level of maintenance.

This DE is used to coat the pool filter grids inside the filter which captures and filters particles as small as 5 microns.

When the pressure rises, it is backwashed in the same manner as a sand filter.

 A slurry of diatomaceous earth is put into the skimmer to “recharge” or “re-coat” the grids.

Some call it the “water polisher” of a pool water system filter.


  • DE filter powder is easily stored
  • Gets your water cleaner than either sand filter or cartridge filter
  • Recharged easily by putting the DE in the skimmer
  • Might go longer in between a normal backwash than sand filters
  • Filters particles and debris better than sand or cartridge filter systems


  • Backwashed every 4 weeks or so
  • Uses up to 50-150 gallons or more of water with every backwash for an above ground pool and 250-500 gallons for an inground pool
  • DE must be purchased and stored
  • Filter must be taken apart and the DE filter grids must be cleaned. Cleaning DE filter is not fun.
  • The grids need to be coated with fresh DE with each backwash

So, out of the three, sand, cartridge, or DE swimming pool filters, which is best for you? Thinking about changing to a different one? Well, this all depends on your needs, situation, pool use, cleaning schedule, time investment, financial considerations, etc...

Helpful hints:

  • Want an inexpensive and easily maintained pool filter? Splashing around for fun and it’s just the two of you? Then you may want to consider a sand filter.
  • You require low maintenance and pretty good filtration? The major use is only on the 4th of July and Memorial Day? Then a cartridge filter is the one you might consider.
  • Money and time are of no consideration and you want the cleanest and clearest pool in the neighborhood. You want to throw a dime in the deep end and be able to see what year it was made. Then check out DE pool filters.

It really depends on your wants and needs. Just remember to ask the right questions to get the best pool filter for your swimming pool.

If that happens to be a swimming pool DE filter , then good for you.
