I submit there's no danger of overheating nor of fire by laying something on top of the machine, as the air intake to the impeller provides internal cooling. However, individuals must determine what's best for their piece of mind and comfort.
I guess I'm very cautious when it comes to electronic equipment. I don't put anything on it that causes reduced airflow or carries the risk of possible fire. My father-in-law is a retired firefighter and my dad used to teach electronics (not that I know a lot about those subjects)... but in any case they both instilled in me a healthy dose of caution when it comes to electronic equipment...
From the S9 Manual there are some warnings
Quote:Blocking the air tubing and/or air inlet of the S9 device while in operation could lead to overheating of the device.
If you put the device on the floor, make sure the area is free from dust and clear of bedding, clothes
or other objects that could block the air inlet or cover the power supply unit.
The airflow for breathing produced by these devices can be as much as 6ºC higher than the
temperature of the room.
So, even though you might use some sort of fabric to muffle the sound, I'd still be careful that the fabric does not fall off the sides enough to cover the air inlet.
If a fire actually DID happen that was traced back to the CPAP... and it was found out that you didn't follow manufacturer's instructions above ("make sure the area is free from dust and clear of bedding, clothes or other objects that could block the air inlet or cover the power supply unit
") it might be possible that you would be found negligent when it comes time for insurance to pay for repairs or replacement to your home due to the fire. I'd take a detailed look through my fire insurance policy to make sure that there isn't a clause in their that would cause them to refuse payment in the case of homeowner neglect. They are in the business to make money and to minimize payouts and they can be terrible to deal with if it's found out that the homeowner caused the fire.
I could very well be over-estimating the risk, and I would agree that the risk is probably very small... I don't know enough to know for sure, so I take the safe route.
You are right - each of us must decide for ourselves.
Let us know what happens once you try the other masks... thanks!
