How to Wash a Pool Filter

If you own a pool, you know how imperative it is to keep the water clean and sparkling. A well-maintained pool doesn't only offer a refreshing place to cool off but also adds tremendous value to your property. To ensure your pool stays in top condition, you need to clean the pool filter regularly. The pool filter operates by trapping dirt, debris, and other impurities present in the water. Failure to clean the filter often can lead to clogging, reducing the filter's efficiency and potentially damaging your pool's pump system. In this guide, we'll look at how to wash a pool filter in five simple steps.

1. Switch off the pool pump and let the filter depressurize

Safety should be a top priority when handling any pool maintenance activity. Before cleaning the pool filter, switch off the pool pump to prevent any injuries from moving parts. As soon as the pump is off, wait for a few minutes to let the filter depressurize.

2. Remove the pool filter

To remove the pool filter, open the valve at the bottom of the filter, then disconnect the filter from the pump. Depending on the type of filter, you may need to unscrew or clamp the filter to detach it. For cartridge filters, carefully remove the cartridge from the filter housing.

3. Rinse the filter thoroughly

After removing the filter, use a high-pressure nozzle to remove the debris collected in the filter. Start from the top and work your way down for a complete clean. Depending on the filter type, you may need to use a specialized cleaning solution. Be sure to follow the manufacturer's instructions when using chemicals.

4. Soak the filter

Once you've removed all visible dirt and debris from the filter, place it in a cleaning solution that's appropriate to the filter type you're dealing with. The solution needs to cover the entire filter, so ensure you're using enough. The soaking process is meant to loosen dirt and debris that may be stuck in the filter's crevices.

5. Rinse and dry the filter

After soaking, remove the filter from the cleaning solution and give it a final rinse using clean water. Since the cleaning solution often contains chemicals, it's essential to rinse the filter thoroughly. Squeeze out any remaining water from the filter and leave it to air dry. Ensure that the filter is completely dry before reinstalling it in the filter housing.


Cleaning your pool filter might seem like a cumbersome task but is vital for the proper functioning of your pool. You should clean the filter at least once a month or more frequently depending on usage. It's also advisable to replace the filter periodically according to the manufacturer's recommendations. With the above straightforward steps, you can keep your pool filter clean and prolong its lifespan. Remember always to follow safe handling practices and use the correct products for your filter type. A clean pool filter equals clean, clear pool water!
