To maintain crystal clear water and ensure your swimming pool remains healthy, regular cleaning of the pool filter is essential. A clean filter not only keeps the water inviting but also extends the lifespan of your pool equipment. There are different types of pool filters: cartridge, sand, and diatomaceous earth (DE), each requiring a specific cleaning method. Here, we explore the best method to clean each type of pool filter.

Cartridge Filters: The best way to clean a cartridge filter is by removing it from the housing and using a garden hose to wash off the dirt. Start at the top, working down in an overlapping pattern while avoiding high-pressure sprays that can damage the filter fabric. For stubborn grime, soak the cartridge in a specialized filter cleaner solution followed by a thorough rinse. It is recommended to replace cartridge filters every 1-3 years depending on use and wear.

Sand Filters: Cleaning a sand filter is typically done through a process called “backwashing,” which reverses the flow of water through the filter and flushes dirty water out via a waste line. To achieve the best results, turn off the pump, move the valve to “backwash,” and then restart the pump for around 2-3 minutes until the sight glass clears. After backwashing, switch off the pump again, set it to “rinse” for about 30 seconds to resettle the sand bed, then return it to its normal filtering position.

DE Filters: These filters are cleaned in a similar manner to sand filters with backwashing. However, once you’ve finished backwashing, additional steps are needed because fresh diatomaceous earth must be added. After backwashing and rinsing, add new DE powder through the skimmer as directed by your filter’s manufacturer manual. It will coat the grids inside your filter system, restoring its full filtering capability.

Furthermore, it’s crucial for all pool owners to maintain proper chemical balances within their pools and regularly check for any signs of damage or wear on their filters. Pool filters should be deep cleaned at least once a season or according to usage frequency—it goes a long way in preserving its functionality and effectiveness.

Keeping up with regular maintenance of your pool filter will save time and money in the long run and keep those summer dips enjoyable for everyone. Regardless of which type of filter you own, ensuring it’s regularly cleaned is arguably one of the best practices for maintaining an inviting pool all year round.
