Description

This is the genuine ResMed side cover for AirSense 10 and AirCurve 10 machines. It's for people who want to run their machine without the humidifier, for example when traveling.

The side cover goes in the slot where the water tub normally sits. With the tub out, there's no water to fill or tub to clean, and the machine is smaller to pack. When you want humidification again, take the cover out and put the water tub back in.

Fits: ResMed matches each color to specific machines:

  • Charcoal (37303): AirSense 10 CPAP, AirSense 10 Elite and AirSense 10 AutoSet.
  • Gray (37335): AirCurve 10 machines.

Does not fit: the AirSense 11, which uses its own side cover (ResMed 39226).

Choosing a color: pick the color ResMed lists for your machine above, so the cover matches your device.

If you get a leak alert: ResMed's guides list 'High leak detected, check your water tub, tub seal or side cover' as a device message. Make sure the cover is pushed fully into place.
