No. 6540-495 is for early-1990s Sundance models. Spas from 2005–2008 typically use MicroClean or other cartridges such as 6540-488S, 6540-501S or 6540-507S. Send us your model and year and we'll confirm.
-
Yes. Sundance changed filter styles mid-year on some Montego, Rio and Redondo models. Compare your old cartridge's length, diameter and end caps to the dimensions above before ordering.
-
Unicel C-4440, Pleatco PSD40 (also listed as PSD40-4) and Filbur FC-2710 are the same size.
-
Rinse the pleats with a garden hose every few weeks, and periodically soak the cartridge in spa cartridge cleaner, then rinse well. Avoid detergent, bleach, household cleaners and pressure washers.
-
Replace it when the pleats are torn, matted or flattened, the end caps are cracked, or it stays dirty after a cartridge-cleaner soak.
-
No tools are required to swap the cartridge itself. Turn off power to the spa, remove the old cartridge from the filter compartment, and seat the new one the same way.
-
Many owners keep a second cartridge so one can soak in cleaner and dry while the other is in use, which keeps the spa running during deep cleanings.
