Description
This filter set contains three filters for MasterSpas swim spas that require one primary filter and two companion filters. The MA-R4 with EcoPur® Charge compatibility and two PWW50 companion filters, all with 1.5-inch male pipe thread connections. Buying them together ensures you replace your full filtration system on the same schedule, keeping your water clean and your spa running at peak performance.
The MA-R4 is designed to accept the EcoPur® Charge Mineral Cartridge inside its filter core, combining mechanical filtration with mineral purification. The EcoPur® cartridge is sold separately.
