Frequently Asked Questions
What filter cartridge does the Master Spas Clarity use?
The Master Spas Clarity runs the PMA10 (also sold as C-3310, 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 Clarity need?
One cartridge. That said, some Master Spas models in the same series use two, so before you order it's worth opening the filter compartment and confirming what's actually installed.
How often should I replace the filter on my Master Spas Clarity?
Most Master Spas owners get 12 to 24 months out of a cartridge before replacing it, 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.
