Replacement Filters for AirSense 11

If you are suffering more frequently from allergies or infections, have a funny powdery taste in your mouth after CPAP therapy or your CPAP machine is making a strained, whining sound, these are common signs that the CPAP air filters need to be replaced.

Replacement is required more often in households that have pets or consist of people that smoke due to additional bacteria more than likely being found in the air.

Check the air filter weekly and replace it at least every month regularly. Replace it more often if there are any holes, blockages by dirt or dust and any form of discoloration.

Standard air filters can be considered the “normal” air filters that come standard with these devices. Hypoallergenic air filters add an additional layer of protection against dust and other air pollutants and are meant for use in areas that have either excessive dust or pollution in the air.

CPAP machines themselves should theoretically last for several years. But in general, accessories such as mask liners tend to wear out due to continuous use, CPAP tubing can get damaged due to constant movement and bending during therapy and CPAP filters tend to stop filtering efficiently due to dust and dirt buildup. If you don't swap the worn-out supplies with new replacements, you risk getting less effective therapy and decreasing the longevity and reliability of your CPAP device.

The CPAP air filter can be considered one of the most important things to check and replace as not only can it damage your equipment if not regularly replaced, your sleep apnea therapy will not be optimal due to the quality of air that you will receive throughout the night for your sleep apnea therapy.
