3 Types of Swimming Pool Filters

The filtering system for your pool is a vital part of maintenance. The better the filtering system, the easier it is to clean and maintain your swimming pool. There are three main types of swimming pool filters used in residential pools, each with their own pros and cons. However, any of the three will work for most pools; choosing which one is up to the homeowner and usually based on their preference for cost, purification and maintenance.

Sand Filters

The oldest and most affordable type of pool filter uses sand to clean the water as it passes through. Sand filters are popular due to their price and simple maintenance. A tank contains a special pool-filtering sand, usually filled about 3/4 of the way full. The size of the tank depends on the size of the pool. Water flows through the tank, leaving behind contaminants in the sand. The sand must be replaced every 3-5 years, but it should be backwashed to clean out debris once a week or after you vacuum your pool.

Diatomaceous Earth (DE) Filters

DE filters work similarly to a sand filter, with a tank that contains grids or fingers that is coated with diatomaceous earth (DE). This is a natural substance created from sea shells and silica that is released by sea diatoms and works well to filter out debris from water. DE filters offer better purification of the water, filtering out smaller particles than sand or most cartridge filters. However, it does need replacement more often than sand; usually more DE must be added after each backwashing, which should be done every 4-6 weeks.

Cartridge Filters

Cartridge filters are one of the most commonly used in residential pools, especially newer pools. These filters come in single and multiple element cartridges which filter out particles. Cartridge filters can last several years before they need replacement but do need to be cleaned 2-3 times a year and degreased at least once a year for maintenance.

If you are installing a new pool or considering changing your filtration system, contact your local pool service to learn more about your options.
