I was a bit doubtful about getting the expensive Air Mini, I normally use an Airsense 10 but was looking for a travel machine. The Air Mini will now be my primary machine its simply amazing. I read a lot of negative reviews about noise and for some reason people saying air from the vents. I find the Air Mini less noisy than my Airsense 10 and no air from the vents at all. There is a ver slight noise from the humidX chamber but really no more noisy than any CPAP machine. As far as therapy results I am getting a much better AHI “events” score with the Air Mini than I get with the Airsense 10. The machine is a dream to travel with I LOVE the bed mount kit and especially the easy mount for under the mattress makes using the Air Mini in a hotel a dream. I used the unit on Premium economy seat power no problems at all. I read some negative about the power adaptor coming loose on aircraft due to the heavy power adaptor , its not that big just that all the weight is indeed on the socket so to speak. Solution , easy = I bought the shortest 2m extension I could, into the aircraft power I plugged the smallest adaptor plug I could find, that went into the extension and the end of the extension I put the Air Mini power adaptor … worked fine and very easy, easier than plugging the adapter into the seat power socket. HumudiX works great. The only negative I give Resmed is that the APP only gives and very simple summary of your nights sleep results, there is no way to get detailed reports. The unit does upload your data to the cloud BUT customers have no access .. only the place you purchased the unit from can access the more details cloud info … THIS IS A BIG BIG mistake I think.. come on Resmed its 2018 you already have your cloud MYAIR solution give Air Mini users who are spending top dollar access to their information. However I give the Air mini 9 out of 10 I love it … 1 point lost for no access to cloud data.
