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.

What Is The Best Filter For Your Pool?

There are three main types of pool filters available, sand, diatomaceous earth (DE) and cartridge, each one offering pros and cons. Determining which filter is best for your pool will depend on how much you use your pool, municipal codes in your area and your personal preferences. Knowing the differences can help you make the best choice for your pool.

Sand Filters

Sand filters clean your pool water by using a combination of pea gravel and sand to filter out contaminants.

  • Pros: Sand filters do not require annual maintenance, and only need the media replaced about every six years in most home pools. Media replacement in sand filters is generally affordable, they backwash easily and rarely require repairs.
  • Cons: The biggest drawback of sand filters is that they provide poor filtration in comparison to other options, and need to be cleaned every week.

DE Filters

DE filters use diatomaceous earth to coat the interior of the filter, cleaning the water as it flows through it.

  • Pros: DE filters provide excellent filtration. They only need to be cleaned about every 4-8 weeks, and do not require a water clarifier.
  • Cons: Not all municipalities allow DE filters. In addition, repairs can be expensive.

Cartridge Filters

Cartridge filters use a pleated filter, similar to filters used in air purifiers. These are typically used for smaller pools or spas.

  • Pros: Cartridge filters are easy to clean and maintain.
  • Cons: Replacing cartridge filters can be very expensive, and cleaning the filters can be more difficult than other types.

Talk with your pool professional to determine which filter is best for your pool, and build an oasis that’s as clean and clear as it is refreshing.
