Marquis Reward Replacement Filter
6-person hot tub · 2000-2021 · 1 filter cartridge
Marquis part 20042, the threaded 35 sq ft filter. Marquis's filter chart lists one cartridge per tub for every Signature Series row, which is the correction to an older note here claiming later Rewards run two. The Reward left the lineup with the Signature Series in 2021. For a 1995-1999 tub, see the Reward Legacy record, which takes a closed-top cartridge that lifts out rather than unscrewing.

Frequently Asked Questions
What filter cartridge does the Marquis Reward use?
The Marquis Reward (2000-2021) runs the PPM35SC-F2M (also sold as 5CH-352, 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 Marquis Reward need?
One cartridge. That said, some Marquis models in the same series use two, so it's worth opening the filter compartment and confirming what's actually installed before you order.
How often should I replace the filter on my Marquis Reward?
Most Marquis owners get 12 to 24 months out of a cartridge, depending on how heavily the spa is used. A larger tub like this holds more water, so the cartridge works a little harder and tends to want cleaning more often. 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.
