Robr, might just need to cover the hose. Depends on how cool the room air is compared to the heated air.

So I turned up the minimum last night from 8 to 9.5 and it took the 90% percentile down from 16 to 15.5, but I ended up with brutal sinus headache around 5am and had to shut off the machine. The headaches also happened the first couple of nights until I turned the pressure down. I'm on vacation for the next week and I'm not taking the machine with me, so when I get back I'll go back to the settings I've been using (8-16) for now. I also figured out the water and hose noise issue, the machine wasn't sitting perfectly flat.

I suggest you bring the machine with you so you have the option to use it. The first trip I took without my machine was my last.
