NovoSleep Hypoallergenic Filters for AirSense 10, S9 and AirCurve, 6-Pack

If allergies tend to flare at night, a hypoallergenic filter puts a finer layer between your bedroom air and your ResMed machine than a standard filter does. This NovoSleep six-pack fits the S9, AirSense 10, and AirCurve 10, with a fresh filter for every monthly change.

Key features:

• The allergy step up: Labelled ultra-fine by NovoSleep, these are the step up from a standard filter for anyone sensitive to airborne allergens.
• A filter for each month: Six filters cover half a year if you follow NovoSleep's advice to change one monthly.
• No tools needed: Each filter sits flat on your machine's air filter cover, which then closes again by hand.
• Protects the machine too: ResMed asks for a filter in place at all times, to keep water and dust out of the device.
