Hot Tub Filter FAQ's

How often do I need to change my filter?

If you clean your filter regularly and thoroughly, your filter can last up to 2 years, but a minimum of 1 year. We recommends having two filters, one in your system and one prepared so you can thoroughly clean the dirty filter while still enjoying your hot tub.

What will happen if I don’t clean my filter?

The filter is responsible for removing dirt and debris from your water before it gets pumped around your hot tub again. Not cleaning your filter will not only result in dirty water, but it will also affect the performance of your hot tub components.

How often should I clean my filter?

There are different levels of cleaning your filter. You should rinse it about once a week. On a monthly basis you can use a filter cleaner spray to keep it clean. Every three to four months you should give your filter a soak. It’s best to do this when you change the water in your tub. For our range of filter cleaning products, click here.
