The SC721 is a fine micro-filter insert for home hot tubs and swim spas of the Armstark and Sundance Spas brands. It captures even very fine dirt and is used together with the Crystalline SC722 cartridge.
This micro-filter cannot be cleaned and must be replaced every 3 to 4 months to ensure proper filtration of the spa water. A clogged and old filter can damage the circulation pump.
