Frequently Asked Questions
What filter cartridge does the Marquis Euphoria Legacy use?
The Marquis Euphoria Legacy (1995-1999) runs the PPM35TC (also sold as C-5423, 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 Euphoria Legacy 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 Euphoria Legacy?
Most Marquis 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.
