Hypoallergenic air filters block fine particles and larger matter from entering your therapy device and, ultimately, your airways. The ResMed hypoallergenic air filter is particularly suitable for people who are affected by hayfever or other airborne allergens.

• Versatile: compatible with ResMed's S9™ series and Air10^TM series sleep therapy devices.
• Hypoallergenic: particularly suitable for people who are affected by hayfever or other airborne allergens.
• Effective: made from a combination of materials that prevent fine particles and larger matter from entering your airways.
• Practical: with normal use, these filters need to be replaced every month. Filters should also be replaced on a one-off basis if they are damaged, torn or blocked by dust or dirt. 
• Please note these filters are disposable and are not suitable for washing.
