This Cartridge Filter Kit includes one replacement filter and one replacement check valve for the SoClean 2 Go. The filter and check valve should be replaced every six months. This kit is suitable for all SoClean 2 Go units.
The Cartridge Filter converts activated oxygen back to regular oxygen as it leaves the SoClean 2 Go chamber. The check valve prevents water from your CPAP from damaging your CPAP electronics.
