Frequently Asked Questions
What filter cartridge does the Master Spas H2X Swim Spa use?
The Master Spas H2X Swim Spa (2004-present) runs the PMA45-2004-R (also sold as C-8341, the same physical cartridge with a different sticker). Confirm by reading the label inside the filter compartment or the part number printed on the end cap of your existing cartridge before you order.
How many filters does the Master Spas H2X Swim Spa need?
2 cartridges. Replace all of them at once. Put a fresh cartridge in next to a worn one and the new one carries more than its share and burns out faster than it should. Pop open the filter housing and count what's installed before you order, just to confirm the number for your serial.
How often should I replace the filter on my Master Spas H2X Swim Spa?
Most Master Spas owners get 12 to 24 months out of a cartridge, depending on how heavily the spa is used. Rinse it monthly with a hose, hitting the pleats at about a 45-degree angle. Soak it overnight in filter cleaner every three to four months. Replace it when the pleats are torn, the seams are stained brown and won't come clean, or a soak no longer drops the post-rinse pressure.
