Types of Pool Filters

Before learning how to clean a pool filter, it’s important to understand the different types of pool filters. The three main types are sand filters, cartridge filters, and diatomaceous earth (DE) filters. Each type requires specific cleaning methods to ensure optimal performance.

How to Clean a Sand Filter

For cleaning a sand filter, start by backwashing the filter. Turn off the pump, set the filter valve to the backwash position, and turn the pump back on. Let it run for about 2-3 minutes or until the water in the sight glass runs clear. Then, set the valve to rinse and run the pump for another minute to settle the sand. Repeat this process as needed.

Every 6-8 weeks, it’s important to perform a deep clean of the sand filter by using a filter cleaner. Follow the manufacturer’s instructions for the specific cleaner you’re using. This will help remove any built-up oils, greases, and minerals from the sand, maintaining its efficiency.

How to Clean a Cartridge Filter

To clean a cartridge filter, start by turning off the pump and releasing the air from the system. Remove the filter cartridge from the tank and use a garden hose to spray off any loose debris. Next, using a filter cleaner solution, soak the cartridge in a bucket for the recommended time according to the product instructions.

After soaking, rinse the cartridge thoroughly with the hose to remove any remaining cleaner and debris. It’s important to let the cartridge dry completely before reinstalling it in the filter tank. Regular cleaning and occasional deep cleaning of the cartridge filter will ensure consistent filtration performance.

How to Clean a DE Filter

Cleaning a DE filter involves backwashing and adding new DE powder to the filter. Start by turning off the pump and setting the valve to the backwash position. Turn the pump back on and let it run until the water in the sight glass runs clear. Then, set the valve to filter and add the recommended amount of DE powder through the skimmer.

It’s important to periodically disassemble the DE filter to clean the grids or fingers. Use a high-pressure hose to remove any built-up DE powder and debris from the filters. Once clean, reassemble the filter and recharge it with the appropriate amount of DE powder. Following this cleaning routine will help maintain the optimal functioning of the DE filter.

Maintaining Your Pool Filter

In addition to regular cleanings, there are several maintenance tips to help keep your pool filter in top condition. Regularly checking and cleaning the pump basket, maintaining the proper water chemistry, and keeping an eye on the filter pressure are essential for the overall health of your pool system.

Cleaning your pool filter is a key part of pool maintenance. By understanding the type of filter you have and following the proper cleaning procedures, you can ensure that your pool stays clean, clear, and inviting for all to enjoy.
