Marquis Hot Tub Replacement Filters
Marquis has been building hot tubs in Independence, Oregon since 1980, and the Vector21, Reward, and Signature lines all see steady demand for replacement cartridges. The good news: Marquis filter sizing is fairly consistent within each series. Pull the cartridge, check the printed part number, and any Pleatco / Unicel / Filbur equivalent will fit.

Quick tip: the fastest way to confirm the right cartridge is to pull yours and read the part number off the end cap. The owner's manual is the backup if the printing has worn off.
