Maintaining the cleanliness of your pool can be challenging without the right filter. Pool filters are crucial for keeping your pool crystal-clear and hygienic, but not all filters are the same. This article is a helpful guide to the three main types of pool filters and how to properly clean and maintain them for optimum performance.

1.   Sand Filters

Sand filters are the most standard type of pool filter and have been used for decades. They work by forcing water through a bed of specially graded sand, trapping debris as small as 20 microns. Over time, sand filters become clogged with dirt and debris, reducing their efficiency and putting a strain on your pool pump. A professional pool cleaning service in Atlanta, GA, can help you regularly backwash your sand filter to remove trapped dirt and restore efficiency.

2.   Cartridge Filters

Cartridge filters use a cylinder-shaped, pleated filter material to catch debris. They have a larger surface area than sand filters, allowing them to capture much smaller particles (as small as 10 microns). Cartridge filters need less maintenance than sand filters but will need to be replaced more frequently.

Cleaning a cartridge filter is simple. Switch off the pump, remove the cartridge from the filter housing, and spray it down with a garden hose to wash off any accumulated debris. Be sure to inspect the cartridge for any damage or wear, and if necessary, replace it.

3.   Diatomaceous Earth Filters (DE Filters)

Diatomaceous Earth (DE) filters offer the finest level of filtration, capturing particles as small as 5 microns. These filters use a powder made from fossilized diatoms – tiny aquatic organisms – to coat a set of internal grids. As water passes through the DE-coated grids, tiny debris particles are trapped.

To clean a DE filter, you will need to backwash it; similar to the sand filters, follow the manufacturer’s instructions for the process. After backwashing, be sure to add fresh DE powder to the filter according to your model’s specifications.

Tips for Cleaning and Maintenance

Proper maintenance and cleaning of your pool filter are important for keeping your pool sparkling clean. Additionally, it’s essential to be on the lookout for signs your filter may need repair so that you can address any issues promptly. Here are some tips to help you keep your pool filter in top condition:

  • Regularly check the pressure gauge on your filter and backwash or clean it when the pressure rises by about 10 psi.
  • Clean or replace your filter cartridges according to the manufacturer’s recommendations, typically every 1-2 years.
  • Monitor the flow of water from your pool’s return jets; if it is weak, it could indicate a clogged filter.
  • Install a timer to ensure that your pool pump runs for at least 8-12 hours daily to keep the water moving and filtered.
