Diatomaceous Earth

Simply put, diatomaceous earth (DE) are the bones of tiny little animals that lived millions and millions of years ago, diatoms. DE pool filters are the most effective pool filtration available but on the downside, it also requires the highest level of maintenance.

This DE is used to coat the swimming 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.

DE pool filters are effective and efficient but a little more expensive to maintain. Some call it the “water polisher” of pool filters.


Pros:

  • Gets your water cleaner than either sand filter or cartridge filter

    • de pool filters,de pool filter,pool filter system,pool filter problems,jacuzzi pool filters,de filters,pool de filter
  • DE filter powder is easily stored

  • 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


    • Cons:

  • 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 cleaning DE filter grids

  • The grids need to be coated with fresh DE with each backwash

    • Swimming Pool Filter Systems

    So, out of the three, sand, cartridge, or DE pool filter, 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...

    3. Money and time are of no consideration and you want the cleanest and sparkliest 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 a 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.
