This AZM SoClean Filter Kit includes one replacement Filter and one replacement Check Valve hose section for the SoClean 2. The Filter and Check Valve should be replaced every six months. This kit is suitable for all SoClean machines with “1200SC” in the serial number.

The Cartridge Filter converts activated oxygen back to regular oxygen as it leaves the SoClean 2 chamber. The check valve prevents water from your CPAP from damaging your CPAP electronics.

To reset your SoClean II after a filter change - press and hold the “manual” and "hourglass" buttons at the same time for about 5 seconds until a smiley face appears on the display. Your SoClean II is reset and will alert you again in 6 months.
