Replacement Filters for AirSense 11 (3 packs)

These CPAP air filters generally need to be replaced once a month but please bear in mind that you still need to check the filter for possible replacement at least once per week due to differing air quality, and to keep your CPAP machine running like new. Signs of requiring a new filter include dust build up, discoloration of the filter itself and if the filter has holes or any visible damage. A dirty or clogged filter can cause the machine to malfunction and in some severe cases cause complete failure. 

The replacement of these disposable filters regularly also ensure that the user is being provided with the best quality of air possible.
