AirSense™ 11 Disposable Hypoallergenic Filters

These genuine ResMed AirSense 11 hypoallergenic filters are built for anyone who wants to remove common allergens and irritants from their therapy air. They use a polypropylene carrier instead of polyester, specifically to reduce the risk of a reaction for those sensitive to polyester materials.

Is This the Right Filter for You?

This is the right choice if you have allergy sensitivities or specifically want to avoid polyester material in your filter. If general dust and dander filtration is all you need, the standard AirSense 11 Disposable Standard Filters cost less and cover the same basic filtration needs.

Blocks Allergens, Reduces Polyester Sensitivity Risk

Made from blended synthetic fibers in a polypropylene carrier rather than polyester, this filter is designed to reduce the risk of a reaction for anyone sensitive to polyester materials. The tightly woven fiber structure also helps trap other common allergens, including dust, pollen, and dander.

An Infrequent Replacement Schedule

This filter is not designed to be washed or reused, but it's built to last: replace it once every 6 months under normal conditions, or sooner if you notice holes, exterior damage, blockages, or other significant wear.

A Note on Pressure Readings

During a significant mask leak or pressure drop, this filter may slightly deform, which can cause a minor discrepancy in your machine's reported pressure readings. This is a known characteristic of the filter material rather than a defect, but it's worth being aware of if you notice unusual readings after an event like a large mask leak.
