Thanks.

We had these in a nursing facility, ask kindly for another unit. They become more noisy after they have been worked-on and their aging process. New ones are definitely quieter. I'm assuming this is a rental unit?
If you bought it, you can put a longer tube/extension, and put it in another room. You shouldn't enclose it.

Yes, it's a rental unit. It has a 50 foot hose on it and it's down the hall and in the family room about 40 feet away, but
it's a lot noisier than a mouse ****in' on a blotter. :-(

They have a compressor in them and can become noisy...I would ask for another unit, preferably, newer.

I originally had a 5 liter unit, with about 29,000 hours, and the Homefill II companion. When I complained about the lengthy
time required to fill the tanks I was given the 10 liter unit that had about 1500 hours on the clock. It was noticeably
quieter but still not what I would classify as quiet.

I was told the Homefill II system required a minimum of 2 LPM to fill the tanks and could use up to 3 LPM. With my need of 3
LPM that put the Homefill II system getting only the minimum for oxygen.

I was hoping there was some sort of sound absorbing material that could be placed near the unit, not encapsulating it, to
help reduce the noise.

Alf, is this a sleeping issue? Have you tried 3M ear plugs?
