Pool Filters

Discounted Pool Filters for Inground & Above Ground Swimming Pools

PST Pool Supplies sells a wide range of pool filters for inground and above ground swimming pools to help protect your swimmers from water pollutants. We sell different kinds of pool filters to suite your needs:

  • SAND FILTERS - Can filter from 20 to 100 microns. Needs manual backwashing every few weeks. Cheap thus easy to replace.
  • CARTRIDGE FILTERS - No backwashing! Easy to operate. Able to filter down to 10 microns.
  • DE FILTERS - Great filtering ability: as small as 5 microns. But it is the most expensive filter type.

Ask yourself, what is my budget in buying pool filter? I would definitely recommend buying the one which does the best filtering so you can get your money's worth.
