This 2-pack of ultra fine disposable filters are specifically meant to be used with the brand-new ResMed AirSense™ 11 CPAP machines. The size-dimensions are specific to these devices and allow the air to be properly filtered by the machine; they are not compatible with the ResMed AirSense™ 10.

The filter should be replaced about every 30 days, or immediately if moderate discoloration is present.
