Cleaning your hot tub filters is an essential part of maintaining a clean and hygienic spa experience. Not only does it help to improve water quality, but it also prolongs the lifespan of your filters, ensuring optimal performance.

To get started, first, turn off the power to the hot tub to avoid any potential accidents or damage. Next, locate the filter compartment, usually found near the hot tub pump. Remove the filter cartridge carefully, making sure to keep it upright to prevent any debris from falling back into the water. Rinse the filter cartridge with a garden hose, using moderate pressure to wash away any dirt, oils, or debris. Avoid using too much force as it could damage the filter.

If the filter is heavily soiled, you may need to soak it in a filter cleaning solution for a few hours to remove stubborn grime.

Once clean, rinse it thoroughly again to ensure all cleaning agents are removed. Allow the filter to dry completely before placing it back in the compartment.

Lastly, don’t forget to turn the power back on, and you’re ready to enjoy your sparkling clean hot tub!
