While not exactly directly on subject, I find it interesting the number of folks diagnosed with a sleep disorder who cannot adjust to wearing anything on their face while sleeping.
My neighbor was diagnosed and tried to adapt and could not and he even tried the minimal in his nose prong setup and got frustrated. He's still a zombie most times... My old boss, same thing. Could not adjust to a mask.
When I started out long ago, there was very limited selection available mask wise. I had no issues and I've always been adverse to anything on my face but after the first few restless nights, it was never an issue.
I started out with a gel mask that had to be heated and fitted to your face, then later on I switched to a Mirage Activa and I've been with that ever since.
Learned a couple tricks along the way. My big one is I run a long breathing hose, like 5 foot long and I put the hose under the covers with me. That way the air passing through the hose gets warmed by body heat and it keeps the humidified air (from my heated humidifier) from condensing in the hose and causing 'rain out'....
...and keeping everything clean. My mask gets washed in anti-bacterial soap and rinsed in HOT water every morning and my humidifier gets taken apart, I use a Fisher Paktel stand alone heated humidifier with a take apart chamber that gets washed every other day along with the hoses in the same anti-bacterial soap and a HOT rinse.
It only gets distilled water. My machine gets it's pre filter washed every 2 weeks and the inner filter changed out at the same time.
When I go on a hunt, I take extra masks with me as most times. cleaning can be an issue. Because I run on a battery pack (which I can charge from a 12 volt outlet in a car or truck or solar, I run with no humidification. The battery packs won't support that much current draw.
In the RV, current isn't an issue so the humidifier is on as well and the humidifier is 110 volt only, whereas the machine will run on 12 volts so the inverter and 110/60 cps current is a necessity.The humidifer on the S8's is integrated into the body. You can remove it and run without but the humidifier pulls it's power through the CPAP itself but at line voltage only.
My wife has her's and I have mine. 2 peas in a pod sleeping away....
We can run both S8's with humidification all night on a pair of Trojan's with the fridge running too and still have 70 percent battery reserve left in the morning. Couple hours on the Champion 2000 watt inverter genny in economy mode and the Trojans are back at full charge for another sleep night.
Works for us just fine and I'm happy and so is the wife.
I know thew 2 CPAP's don't tax the AIMS Power inverter at all. The internal cooling fan never comes on and the case is barely warm to the touch.
Glad I went with a 1000 continuous 1500 watt surge unit instead of a lesser output inverter. While it cost a bit more, it was worth the extra bucks. Main reason besides output and low idle current draw was the full shutdown remote. The Inverter is tucked away in the same bay where my FW tank, water pump and battery bank is so I don't have to access it at all. Just use the remote on and off button. It has a green LED to show it's energized.
