Hot Tub Filters

Your hot tub filter is one of its most important components, providing a means of removing suspended particles, grease and debris from the water. Your filter needs cleaning regularly to ensure that it works efficiently.

How to clean your hot tub filters

Ideally, filters should be replaced every 12 months but, if you are able let your filters dry between uses they will last longer. For this reason it is sensible to keep two sets of filters and alternate their use with each clean.

High temperatures and a wet environment can make an unprotected filter surface a target for the growth of bacteria. We offer a range of filter cartridges where the surfaces are coated with microban® antimicrobial protection to inhibit the growth of bacteria and reduce staining, odours and degradation of the filter surfaces.

Microban® hot tub filters are easier to clean and also stay fresher between cleanings.
