I found the AirTouch F30i to be extremely comfortable right out of the box—the cushion is soft and gentle on the skin, and the overall design makes it easy to wear through the night. I really like the over-the-head hose connection, which keeps things out of the way while sleeping. That said, I did experience some leaking, and I’ve personally had a better seal with the F40, but I think with a bit more time and adjustment I can dial in the fit. I typically use nasal masks like the AirTouch N30i, and switch to hybrid styles like this when dealing with seasonal allergies or a cold, and this one fits that role well. Shipping was fast and free, which was a nice bonus. Overall, I think it’s definitely worth trying if you’re interested in a hybrid-style mask and prioritize comfort.
