ResMed F40 AirFit mask

[HalfAsleep]

Enjoy the F40. I love mine. IMO it's key to get the right size. There's a headgear size and a mask size. Also, you have to set your xPAP unit to "pillows" instead of full face mask. It says so right on the packaging.

My experience is that the mask gets a little wild when the pressure goes above 14, but I've checked, and you're not in that category. Good thing.

As an added tip, I've found that the mask sticks super well if I wipe it with a mask wipe and also wipe my face in the mask area. If I get exasperated in the night with a leak, I give my mouth another wipe, and it sticks! It never wakes me up again the whole night. I would guess I'm wiping off facial oils and sweat that are making my mask a bit slippy. Such an easy solution.

Also, the mask can sound like it's leaking when it's not.

I have to tighten the F40 a bit tighter than I like, but my headgear is tricked out with Pad-a-cheeks, so there's no discomfort. They might actually help with leaks.

Thanks for the tips! I've been very happy with my AirFit F30. If the F40 doesn't work out, I'll stick with what does, the F30.

I plan to get the F40 soon, but wonder about sizing. The cushion sizing guide indicates I should use a medium cushion. There are also 3 different sizes for the headgear. I haven't found any size guide for the headgear. How do I know which size to order?

I'm currently using a Fisher & Paykel Evora, which is similar, but has some key differences I don't like. Their size guide also indicated I should get a medium cushion, but after trying medium and large for a couple months, I definitely do better with the large. (Harder to breathe with the medium.) Are they similar enough that I would also do better with the large cushion on  the F40?

I'm going to stop by on Monday and make the swap. The AirFit F30 I'm trading in is a size medium. The AirFit F40 I'll be picking up is a medium. 

While I'm there, I'll ask about sizing and what they think would suit me best. More-times-than-not, the headgear has enough adjustment to make do. 

If push turns to shove, I'll order a large cushion if needed.

@mecutl3r What size hat do you wear? That's your answer on headgear size for the F40. It's also a HUGE range for one size, so plenty of adjustment. As for cushion, there's a little chart on their manual. Look it up and print it out. I would say, the cushions are "true to size", but how wide your nostrils are is a factor, as well as how long the distance between nostrils and just under your lower lip. This can vary by ethnicity.
