How long should Unicel pool filters last?
While most pool filters need to be changed every season, 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 2 seasons or more, depending on your level of pool filtration and filter cleaning routine.
