How long should ProAqua hot tub filters last?
While most hot tub filters need to be changed every six to twelve months, ProAqua brand filters are made with premium filtration media that delivers 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.
