Why It's Important to Clean Your Hot Tub Filter

The filter in your hot tub helps keep your hot tub water clean and pure. Over time, filters collect oils, hair and other debris, which decreases their efficiency.

Not cleaning your hot tub filter regularly can lead to cloudy water, unpleasant odors and a malfunctioning tub, potentially leading to expensive repairs. Regular cleaning of your hot tub filter ensures not just the hygiene of the water but also the operational efficiency of the hot tub's heating and filtration systems.

The Cleaning Process

How Often to Clean or Replace a Hot Tub Filter

There is no set rule for the frequency of cleaning your hot tub filter. It largely depends on how often you use your hot tub and the environment around it. As a general rule: 

  • Weekly quick clean: A quick rinse with a hose helps to remove loose debris, prevents buildup and extends the filter's life.
  • Monthly deep clean: A more thorough clean, using a specialized filter cleaning solution to dissolve oils and grime lodged deep within the filter fibers, also works to extend the life of your filter.

How Often to Replace Hot Tub Filters

When cleaning your hot tub filter weekly or monthly, keep a check to know when it needs maintenance or replacement. Typically, a replacement is required around the one-year mark for active users.

Caution

Using a hot tub without a filter or with a heavily clogged filter can seriously damage the pump and heating system.

Following these steps on how to clean a hot tub filter will ensure your hot tub remains functioning smoothly with every use.
