How long should Unicel pool and hot tub filters last?
While most hot tub filters need to be changed every six to twelve months, Unicel brand filters are made with REEMAY premium trilobal filtration media that delivers 45% more surface area over standard rounded filter fibres and can last up to 18 months or more, depending on your level of hot tub use and filter cleaning routine.
