How to Clean Your Hot Tub Filter

It’s a dirty job — but someone has to do it. Actually, cleaning your hot tub filter is a pretty straightforward process. To help you get your filter maintenance down pat, we’ve put together a  guide that not only tells you how to clean your filter effectively but how often it must be done.

Let’s dive right into our filter cleaning crash course.

1. Helpful but Not Essential

Most experts recommend keeping a spare hot tub filter on hand. This way, whether you run into issues or you’re performing filter maintenance, you can install your spare so your hot tub can be used as normal.

2. Weekly Schedule

Cleaning your filter each week may not sound like a lot of fun, but it’s an essential task to keep your spa running well.  

Using cool water from a hose or a faucet, spray your filter at an angle to flush dirt and debris out from between each of the pleats.

While this may seem like the perfect job for your power washer or dishwasher, resist the urge to use either. While these more powerful cleaning methods may seem like a great choice, they’ll break down the filter’s fibres.

Once clean, allow your filter to dry completely before reinstalling or storing it. If you don’t want to wait for it to dry, pop in the spare.

3. Monthly Schedule

One each month, the filter will need to be washed with a special cleaning solution that’s available for purchase at most hot tub dealerships. The chemical cleaning solution should be sprayed directly on the filter. Allow to sit for 15 minutes and then spray between the folds to remove all suds. If the filter is not completely rinsed, you could end up with foamy hot tub water.

You should always use a designated hot tub filter cleaner for this task. While it can be tempting to use household cleaners in a pinch, they can damage your filter and cause issues within your entire filtration and spa system.

4. Quarterly Schedule

Once every three months, you should take the time to soak your filter in a special cleaning agent. This step can be pretty easy to forget. One of the best ways to avoid this is to do it each time you change your hot tub’s water, which also should be done every three months.

Begin by mixing the filter soak according to the manufacturer’s directions and then place the dirty filter in the solution. Once it has soaked for 24 hours, rinse it well with water. Allow it to dry thoroughly before reinstalling or storing it.

By following these simple steps, you’ll be able to keep your filter in tip-top shape.
