Question for AirMini users.

[Jimbeau]

I’m past the initial learning curve with my new AirMini but still have a couple unanswered questions. 

1) I don’t understand why the masks are louder. The machine itself is quiet, its the mask that has me slightly baffled. Pun intended?
Before jumping to conclusions please understand that I’m not just comparing the AirMini P10 to a regular P10. I’ve done that but also compared the AirMini machine with the same standard P10 that I use on my home machine. I accomplished this by using the zephair adapter to convert to slimline tubing and conventional mask. 
So I’ve compared the AirMine with with the exact pressure settings as my home unit by using both the proprietary AirMini mask and a standard model. The result is always a louder mask when connected to the AirMini. 
The source of air noise seems to be coming from the mask’s vent port. 
With all this said I’m doing ok with the level of mask noise, it’s just higher than I prefer.

2) The Zepair connector. Are there any disadvantages to using this with a conventional set up? I understand you lose the certain humidification options but anything damaging? Anything that could hurt the machine, degrade, or improve my therapy? 

Thanks!

Just a thought; Being totally ignorant on the AirMini, isn't the hose a small 12mm diameter? If so, this will require a much higher air velocity to achieve the same volume at a given pressure. An increased velocity, especially in a ribbed hose, will generate increased turbulence and added noise.

That’s an excellent point about hose. Bernoulli's principle is hard to argue with! 
The only thing is I swapped to the slimline hose & mask by using the zephair adapter, which attaches directly to the AirMini. So I was actually using the same hose, and mask from my home machine but connected to the adapter instead of directly to the air mini.

Great point though and it really has me thinking. Possibly the noise is due to the narrow outlet size of the AirMini rather than the hose.
 
Interesting concept! 

Thanks!

Cool thing with using standard hose is you don't necessarily lose humidification. There are inline humidification devices called heat-moisture exchangers (HME) you can use with a standard hose. I've used them with the airmini as well as standard resmed autoset 10 to avoid needing water and filling the tank.
