Hope anyone can help. I use a cpap machine for my sleep apnea, however i basically havent used it for 2 months.

Reason being it wakes me up and gives me a restless sleep, i now sleep better without it!

Perhaps it is blowing too strongly, as ive lost about 80 pounds since surgery 5 months ago.

There is a whistling sound coming out of it at the back somewhere and it drives me up the wall. Anyone had that problem? What could cause it?

Also it has a weird smell lately.

I cleaned the pipe every so often with soap and Water. Also took out the little material stuffing in the back to flip it with my fingers to clean it like i was told, though nothing was there, like no dust or anything.

I am smoking again however and that obviously mist have an influence on the smell of the air - but honestly i really dont think it is all that.

Is there some way i can open up the little machine thingy and perhaps clean out its innards?

Does anyone know what i am talking about. Almost a smell of a cupboard that has been closed for too long.

It just makes me not wanting to use it.

And i want to use it though because obviously i need it! Hope someone has some advice ????

I'm no expert, but i guess there are different cpap machines, so I'd suggest googling the model number and manufacturer name for technical support...

If there's a whistling sound coming from the back, could the hose not be completelt pushed into the connection on the machine or could the hose have too much wear or a small leak?

My cpap has a seperate button to open and clean the humidifier. There are so many on the market now. If u can find ur model number google may help. They send me extra filters so I try to change it and rinse the hose with vinegar Water to help the funky smell it gets sometimes.

The whistling could be cracked plastic perhaps and the noise of the forced air leaking. A new Hose might help
