The ProAqua filter for Master Spas Twilights series from 2009 +. Also a compatible replacement for Master Spas OEM X268365. This filter can be an alternative longer version 1-piece replacement for pre year 2004 Master Spas Eco-Pur PMA-EP2 systems. This single cartridge replaces both the outer and the inner filter. These brands have used different filter sizes for many models over the years.

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 two years or more, depending on your level of use and cleaning routine.
