Pool filters remove dirt, debris, oil, skin, hair and organisms from your pool water that slip through the skimmer box. As water passes through the filter, impurities are trapped and water returns to your pool in a clean and pristine condition.

There are three main types of pool filters: cartridge, sand or diatomaceous earth (DE). All three will do a good job of filtering your pool but each has it’s advantages and disadvantages.

Cartridge Filters

Cartridge filters use less water and filter finer particles than sand filters. Cartridge filters also require less water flow and less energy to effectively filter your pool water. Ideal for tight spaces, they are simple to operate and maintain, and only need to be cleaned when the pressure gauge indicates an increase in pressure.

Sand Filters

Sand filters have traditionally been the most popular filters in Australia. Robust, durable and low in maintenance, sand filters can also be filled with different filtration media such as Zeolite or glass to filter finer particles. Sand filters strain the water from the surface of your skimmer box, filtering out impurities. These impurities eventually clog up the sand, which should be cleared every 6-8 weeks using a process called backwashing.

Filter Media Options: Sand, Zeolite or Glass

Diatomaceous Earth Filters

DE filters provide the best filtration for your pool, but require more maintenance. Operating similar to a sand filter, DE filters use fossilised diatom to catch debris. However when you backwash the filter, some of the DE material is washed away and needs to be refilled.
