ResMed AirSense 11 End Cap is backordered and will ship as soon as it is back in stock.
This side cover is used in place of the humidifier tub; it will automatically turn off the HumidAir humidifier.
This is the side cover for AirSense 11 machines.
Great fit for when traveling and won't need the humidifier function. AirSense 11 is incredibly quiet also.
