If you use your SoClean daily with the default seven-minute cycle, you should replace your filter and check valve every six months. This SoClean 2 cartridge filter kit includes a replacement filter with an attached O-ring, as well as one replacement check valve. The filter transforms air within the system to regular oxygen as it exits the SoClean 2 chamber. Meanwhile, the check valve makes sure water doesn't damage any of the electronic components.

This kit is compatible with any SoClean machine with "SC1200" in the serial number.
