A clean and fully functional hot tub filter is essential to maintain clean, clear healthy water. 

Surespa hot tub filters are manufactured in New Zealand using Reemay Advantage™ filter media which employs 100% polyester synthetic fibres to provide optimum filtration efficiency.

This filter is also available with microban protection which makes the filters easier to clean and keeps them cleaner and fresher between cleanings. Microban protection continuously fights the growth of damaging microbes such as bacteria, mould and mildew that cause stains, odours and product degradation.  Find out more about microban hot tub filters here.

The high temperatures and a wet environment of a hot tub makes filter surfaces an ideal environment for the growth of bacteria. It is important to clean grease, scale and bacteria from your filters regularly using Surespa Powder Filter Cleaner and to replace hot tub filters approximately yearly.
