Replacement Silicone Check Valve fits SoClean 2 Machines

Replacement Silicone Check Valve  This is the valve between the So Clean 2 machine and the injection tube connecting to the ResMed or other machines humidifier chamber. CPAPfix.com recommends that you replace this filter every six months. You can purchase the cartridge filter kit from us separately which is designed to convert activated oxygen back to regular oxygen as it leaves the chamber.  We also recommend that you replace the regular rubber injection hose with our upgraded silicone hose kit.
