NovoSleep Standard Filters for AirSense 10, S9 and AirCurve, 3-Pack

Every S9, AirSense 10, and AirCurve 10 needs an air filter in its filter cover, keeping dust and stray particles from being drawn into the machine and on toward your mask. This NovoSleep three-pack gives you the everyday white filter with two spares, so a change never waits on an order.

Key features:

• The everyday filter: It suits most bedrooms, and the hypoallergenic version is there if allergies are a concern.
• Three in a pack: One goes in now and two wait in the drawer, which covers several months at NovoSleep's suggested pace.
• Changes by hand: Open the air filter cover, lay the new filter flat, and close it again, with no tools involved.
• When it's blocked: On S9 and AirCurve 10 machines, a blocked filter can bring up an on-screen message asking you to check it.
