Swim Spa Outer Filter with Orange Receptacle

Original Equipment Master Spas Filter Cartridge. The Swim Spa Outer Filter with Orange Receptacle is used on all H2X Swim Spas and Michael Phelps Signature Swim Spas by Master Spas from 2017 to 2024.  This outer filter has an orange Eco Pur Charge receptacle on the top of the filter, and is embossed with "Master Spas PMA-R4 / X268549". It is used in conjunction with the Eco Pur Charge Filter X268532. Replacement parts from the manufacturer guarantee an exact fit and match, and are the best quality replacements available. Master Spas is currently doing a rolling change with OEM Filters.  You may receive the blue filter (pictured) until inventory is depleted, or you may receive the new Master Clear Filter which will be grey in color.  Rest assured, they are both the same filter, and they are both OEM, and supplied directly from Master Spas.
