Master Clear® MA30 Filter - 2" FPT (Female Pipe Thread)
The MA30 is the current-generation companion filter for a wide range of MasterSpas hot tubs and swim spas. Built with a 2-inch female pipe thread connection, it provides dedicated mechanical filtration and works alongside the MA-R3 primary filter in spas that require multiple filters. Unlike the MA-R3, the MA30 does not house an EcoPur® Charge Mineral Cartridge.
This is the current-generation replacement for the PWW35L filter.

Important Note for Pre-2025 Spas
MasterSpas hot tubs and swim spas manufactured before 2025 used a 1.5-inch female port. The MA30 uses a 2-inch female thread. If your spa was manufactured before 2025, you may need a thread adapter for compatibility. If you know you need one, it is available for purchase separately on our site. If you are unsure, contact us before ordering and we will confirm the right fit for your specific model and year.
Replacement Schedule
Replace every 12 months under normal use, or every 6 months with heavier use.
Due to the nature of filtration products, we cannot accept returns on opened or incorrectly ordered items. Please verify your model and production year before purchasing.
