Hot Tub Filters
Hot tub filters trap dirt and keep the water in your hot tub clean and free of bacteria. A hot tub without a properly sized filter or a filter that's broken or dirty filter will not clean the water properly and may become dangerous to the health of swimmers. Spa filters are most commonly cartridge filters. Replacement cartridge filters for spa cartridges are easily available. The type of replacement cartridge your hot tub requires will depend on the brand and type of filter, the cartridges diameter as well as the type and size of the end and bottom caps.
