What is the difference between the ResMed AirFit F40 and AirFit F30 full face masks?
The differences lie in the cushion, mask to hose connection and headgear.
Cushion: The AirFit F40 features a 100% silicone cushion, while the AirFit F30 has a silicone cushion with a plastic backing.
Mask to hose connection: The AirFit F30 mask features an elbow swivel connection while the AirFit F40 comes with a short tubing and swivel.
Headgear: The AirFit F30 has five adjustment straps, including one at the top of the head. The AirFit F40 has four straps and lacks the top crown strap.
I like to sleep on my stomach. Is the AirFit F40 a good choice for me?
The AirFit F40 is optimized for side and back sleeping so stomach sleepers may find better comfort with a tube-up full face mask. These masks connect the CPAP hose at the top of the head, allowing for more freedom of movement during sleep.
How do I clean my AirFit F40 Full Face Mask?
Weekly cleaning: headgear, frame
Daily cleaning: cushion, vent ring, short tubing with elbow
- Disassemble the mask.
- Soak the mask parts in warm water with mild soap. Avoid soaking for more than 10 minutes.
- Shake the parts in the water and use a soft bristle brush to gently clean the holes in the vent ring.
- Rinse all parts thoroughly under running water, squeezing out excess water from the headgear.
- Lay parts out to air dry away from direct sunlight.
How often should I replace my AirFit F40 mask?
To maintain the best fit and seal for your CPAP therapy, we recommend replacing the entire mask, including the headgear and frame, every 6 months.
The silicone cushion, however, may need to be replaced more frequently, typically every 2 to 3 months. Silicone naturally softens over time, which can affect its ability to create a good seal.
My AirFit F40 Full Face Mask is leaking. What should I do?
- Gently pull the mask away from your face and then release it, allowing the cushion seal to inflate and settle comfortably under your nose and around your mouth.
- Make sure to clean both your mask cushion and your face, as facial oils can interfere with the seal.
- Ensure you're wearing your AirFit F40 mask according to the fitting instructions in the user guide or in the videos below. The way you put on the mask significantly impacts the seal.
- Adjust your headgear as necessary.
- Try a larger or smaller cushion or headgear size.
- Replace any worn out mask parts.
If your CPAP mask still leaks after following all those troubleshooting steps, a different mask style may be a better option. Feel free to contact RespShop for assistance in choosing a different mask.
