Hot Tub Filter & Pool Filter Cartridges

Shop replacement cartridges for hot tub filters and pool filters to use with some of the most popular filter models. Don’t get short without a spare hot tub filter cartridge next time you plan a relaxing night with friends in the garden, or keep your holiday home well stocked with the great range of filters for hot tubs available at Finest Filters. 

Hot Tub Filter Cartridges

We have a selection of hot tub filter cartridges designed to be compatible with filter models including the Pleatco PWW50P3, Unicel 6CH-940, and Filbur FC-0359. Our hot tub filter media comes in packs of 1, 2, or 4, depending on how often you use your hot tub and will need to change it. 

These filters for hot tubs are made from trilobal fabric, which creates an expansive filter surface area that can hold a large amount of sediment, without affecting the tub’s flow rate. This material also makes it easier to clean your hot tub filter, meaning you shouldn’t need to replace it as often. 

Pool Filter Cartridges

We also stock a collection of swimming pool filter cartridges, which can be used with the following pool filters: Intex Type A, Intex Type C, Bestway Type III, and 59900E/29900E. Our pool filter media comes in single packs, or sets of 2, 3, 4, or 6. 

All of our hot tub filters and pool filter cartridges feature reinforced end caps that are highly resistant to chemicals often found in pool and spa applications, including chlorine. Shop the full range of replacement filter media available at Finest Filters today. If you can’t find what you’re looking for, please don’t hesitate to contact us.
