Does anyone or their partners use a CPAP machine?

We need to get one for DH and I am struggling with the different ones out there, and the massive variation in price.

There seem to abe a few main brands available, but the two I like the look of, and can best afford, have the least information available. Add to that the incredibly high price compared to the US - but the US sites will ship internation, but only if you have a script from a US Dr - not sure how that one works!

Anyway, if you/your partner have one

Which one do you have
Does if have a humidifier
How loud is it - i.e. can you still get to sleep easily

TIA
My Mum had one which has just broken after over 10 years. It was a Fisher & Paykel, I'm fairly sure the replacement is too. I don't know which models. The part which finally broke was a cooling fan in it.

The newer ones are very quiet to silent I've heard. I thought they all came with humidifiers?
