The pool filter is the most important part of your pool and is essential for the health and safety of you and your family. Yes, chlorine or salt  in the pool will kill bacteria, it is the filter that removes the bacteria and debris from the water, keeping the pool safe and pristine.

There are three types of pool filters for both in-ground and above-ground pools: a sand filter, cartridge filter and diatomaceous earth (D.E.) filter. Each type has different a filtration mechanism, lifespan and maintenance needs.


  • Traditional type of filter
  • Has a simple cleaning system in which you “backwash” the filter by running the water through it in reverse and out through a waste line
  • Replace sand every five to seven years


  • Easiest filter to install
  • Uses pleated cartridge filters
  • Remove and rinse cartridges every six months or when internal pressure rises above baseline
  • Replace cartridges every two to five years
  • Uses and wastes less water than sand filter


  • Filters with a powder made from fossilized diatomes, a type of microalgae
  • Requires the most maintenance of the three filter types
  • Requires backwash cleaning every month
  • Filter grids/rods should also be rinsed or soaked regularly to clean them thoroughly
  • Will need more D.E. powder added to grid/rod after every cleaning
  • Replace filter grids/rods every five to seven years
  • When inhaled, D.E. powder is a carcinogen, so wear a dust mask and exercise caution whenever handling the filter.
