This is a much better fit for me and my sleeping style than the previous ones I got, the full face F20. I'm an asian male with a flatter nose and there was too much leakage from that previous mask. That said, I wish I looked more carefully because I got the standard frame and I think its too loose on my head, I would probably do better with the small frame. Even though I have a big head, there is a lot of give in the current fit so that when you toss and turn, sleep on your side, as I often do, the nasal pillows move. Also, I am not used to the fact that the attachment has vent holes in it so that some of the pressure escapes there. This was not true of the F20. These are things to consider when you're purchasing.

10x!

Didn’t know that the machine had filters until my wife asked me if I’ve changed them. I still have some left from the ones that came with the machine but got these for the following times. Speedy Delivery and great service!

Filters

So easy to change these, and so important. When I forget to change them, I notice an odor. Change them, and the odor disappears. Don't forget to change your filters!

Hypoallergenic filters, great service

It was a no brainer. Let’s see, a machine pumping air directly into your nose and lungs for 7-8 hours, maybe that air should be as allergen-free as a filter can make it. Done. Make sure you check your order when it arrives. The filters are tiny and nondescript, so it’s easy for them to be switched before shipping. My initial order received was for Airsense 10 filters, which, surprisingly, are not at all compatible with an Airsense 11 machine. Who would think? Luckily the customer service was much more precise and I received the correct filter with lightning speed and zero BS about returning the others. That’s also what I like, in addition to no allergens: no BS. I guess you could say I’m allergic to that as well.

Perfect fit

As always with all my purchases from Lofta this was a perfect fit. I know you can buy cheaper universal filters but these really are better quality and are a perfect fit.

Resistant and efficie

Don’t let them deceive you. They seems so fragile. But when you see how much dust and filthy things it traps, you would ordered them over any other else. Thanks Lofta, you all.

Works great, no problems

These appear to be just as good as the ones made by ResMed, but are significantly cheaper. I changed the filter, and the machine works the same as before, no issues.
