Exclusively for the ResMed AirFit F40 Full Face Mask, this fully silicone under-the-nose cushion provides a soft and adaptive seal all night long.
AdaptiSeal™ technology ensures the cushion rests securely under your nose and stays in place, no matter how you move.
Available in three sizes — small-wide, medium, large — it’s easy to find an AirFit F40 cushion that works for you. All sizes are compatible with the same mask frame, so you can size up or down with minimal hassle.
Clean your cushion, along with the vent ring, short tubing, and elbow after every use.
Disassemble the mask. Please refer to your AirFit F40 User Manual for complete instructions.
Soak the mask parts in warm water with mild soap. Shake the parts in the water and use a soft bristle brush to gently clean the holes in the vent ring.
Rinse the mask parts well under running water and air dry away from direct sunlight.
RespShop recommends replacing CPAP mask cushions every 2-3 months in order to maintain an effective seal. Silicone cushions soften over time and replacing your cushion regularly helps make sure you continue to receive optimal therapy.
Q. I need a large headgear with a large mask, but the f40 bundles do not have this as an option, so I was going to buy the mask and headgear separate. The problem is I do not get the small tubing + filter to connect to the CPAP. Is there a way for my needs to be met?
A. Yes, the F40 can be purchased complete and replacement cushions and headgear can be purchased separately. You will need to order the mask complete and then add a larger headgear.
Refer to the Fitting Template to find your cushion size.
Using the template:
Stand in front of a mirror and place the template under your nose.
Position your nose above the blue Medium cushion box. Check if your nose width and length fit into the box. Repeat the process with the purple Small-Wide and gray Large cushion box.
Choose the cushion size that allows your nose to fit inside the box. If your nose fits into more than one box, choose the box that is the best fit for your nose width.
