How to Clean Hot Tub Filters
Cleaning your hot tub filters improves their efficiency and helps maintain sparkling water.
You should establish a routine filter cartridge cleaning cycle based on the amount of hot tub use and the sanitizer you use. Cleaning hot tub filters every 2 or 3 weeks is the most usual routine. If you use ecoONE you will probably find if sufficient to clean them monthly.
[NB: If you use Aquafinesse you will probably find that you need to clean your filters at least weekly].
- Remove the cartridge from the filter housing and use a garden hose, or a tap, to wash down the filter element. Work from the top of the filter, with the water flow at a 45 degree angle, and wash all pleats, ensuring that you remove an debris stuck between the pleats. Alternatively you can purchase various filter cleaning tools to help with the job.
- Rinse the filter until all visible debris is rfemoved..
- Soak the filter cartridge for at least 1 hour (overnight is preferable) in a clean, suitable size bucket using a proprietary filter cleaner solution. Alternatively use a spray-on filter cleaner and rinse very thoroughly after 10 minutes.
- Rinse the cartridge again after cleaning to remove any traces of cleaning solution.
- If you want to make it really easy, place the filters on the bottom shelf of an empty dishwasher and sprinkle all over with a powdered filter cleaner. Run the machine on a standard 50 degree wash cycle.
- Always dry the filters before reinserting them back into your hot tub. This ensures that the filters perform optimally and last longer. Let them dry naturally, don't use artificial heat. It is a good idea to keep a spare set of filters and rotate them at each clean so that they can dry completely before reuse.
- Finally, any grit or debris inside your filter compartment can easily be removed with a spa vacuum cleaner.
