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.
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.
Note : If replacing an old Pleatco brand threaded filter cartridge, be aware that these have a removable male pipe thread fitting which slip-fits into a hole in the bottom of the filter. You may need to unscrew the pipe fitting from your spa's filter housing if it did not come out with the old filter (many spa owners are not even aware that the fitting is still in there) before you can screw in your new filter.
The filters that we sell are moulded as a single piece, so that the threaded fitting always comes out of the spa with the filter.
