ResMed's AirFit F40 Full Face Mask improves user comfort with a minimal, lightweight frame that creates an open field of vision; and a soft silicone cushion that adapts to the face maintaining a comfortable seal all night long. AirFit F40 includes plush headgear with only four adjustment points - simplifying fitting and use.

ADAPTISEAL SILICONE CUSHION: Each AirFit F40 Mask features ResMed's AdaptiSeal Silicone Cushion. These hypoallergenic cushions are soft, lightweight, and allows for a stable, comfortable seal on your face while you’re sleeping - regardless of how you move.

DESIGNED FOR COMFORT: Featuring a fully flexible frame that's soft on your face, a AdaptiSeal Silicone Cushion and a short tube, AirFit F40 enables freedom of movement while maintaining a secure seal throughout the night. Its minimalist design accommodates the use of glasses for reading or watching TV. With four easily adjustable points and convenient magnetic clips, it offers user-friendly functionality.

ADVANCED QUIETAIR DIFFUSER ELBOW: AirFit F40 features ResMed's QuietAir Elbow with almost silent air dispersion and a more gentle exhaust airflow than ever before so everyone can enjoy a quiet, comfortable night's sleep. F40's elbow also features quick release squeeze-tabs so it's easy to detach with one hand at night; and it rotates 360° with an independent tube swivel to reduce tubing drag and resistance.

Sealing

Did not seal well, it needs an adjustment on the top strap to fit properly.

Comfortable

Compared to the Airtouch F20 I had used previously, this is much more comfortable and has a more secure seal. Very satisfied.

Much better than the full face mask

I rarely use a nasal cushion because of chronic nasal congestion. Instead I have been using the full face mask. While it works fine I am always aware that it’s there and have to be careful when I turn so I don’t cause leakage. The F40 rests under my nose so there is airflow through the nose at times. It’s more comfortable and less sensitive to positional change. I will buy again

Fits and seals well

It fit better than any other mask my wife tried.

Best CPAP mask I have used in 20 years

So comfortable! This is my first full face mask and it exceeded all my expectations. Fits great, stays in place, virtually eliminated persistent leaks I experienced with other masks, minimal or no mask marks. It is difficult to know what size headgear to order since the sizing guide is only for the cushion, but that is my only complaint. Highly recommend for side sleepers!

Review F40

Difficult at the beginning to regulate your breathing pattern. Hatd to determine size to purchase through template.

Not for me

I tried it a couple of times and every time my tongue was stuck to the roof of my mouth. When I got it tight enough not to leak it gave me a headache.

Reviewer1282157052 August 31, 2025

Comfy

I like this unit. I bought a medium & it fits well and is soft and not too intrusive. I can now choose to switch between this one and my airfit P10 nose cushion small face hugger. However, this thing is a new item and I couldn't find it elsewhere cheaper. BRING down the price for us poor folk!!

F40 CPAP Mask

Great experience! Easy to order! Good price! Fast delivery! Face mask easy to use and works well!

Reviewer688381692 June 12, 2025

Soft

Love the soft cushion. Less evasive on my face which I love. Great for a back sleeping which I’m not. I’m a side to side sleeper it causes the mask to leak a little. That’s why I only rated it 4 stars! It’s in my mask rotation now!
