Swimming Pool Filters

E-Z Test Pool Supplies, Inc. has been in the pool business for over 30 years.  Pool filters have evolved over time and there are currently three main types.  We have provided the following information to help our customers understand the benefits and differences between Sand, Cartridge, & DE Filters.  If you have any questions please contact us today by phone or e-mail.

1) Sand Filters

Add sparkle to your above ground pool and spend less time maintaining it.  Sand means filtration is between 10 - 100 microns- it requires minumum maintenance.  An easy turn of the muti-port valve accomodates routine backwashing.  A Bottom drain makes servicing wasy and winterization fast & easy.

2) Cartridge Filters

Cartridge filters filter between 10 - 20 and offer the convenience of ease of use.  No backwashing, therefore no loss of water or pool chemicals.  To clear the filter simply remove the cartridge and clean with a filter degreaser.  Cartridge filtration is fast, easy & convenient.

3) DE Filters

Diatomaceous earth- a material substance- is so fine it traps dirt & debris as small as 5 microns, or 1/10 the width of a human hair. What is means to you is sun tan lotion, dust, bacteria are trapped int eh filter leaving your water sparkling clean.  DE Filters will remove copper, iron, and manganese from the swimming pool water
