Do you have hard water? When our water softener broke, I had to soak the neb cups in vinegar prior to boiling them to get rid of the calcium deposits.
As for the pari proneb ultra II. Don't think the receipt matters. I just happened to find mine, but they can look up the serial number on the bottom of the machine and all of them have a 5 year warranty on them.
Only problem is that you'll have to contact them and mail the machine in to them and then wait a couple weeks for them to send a new one back to you.
Are you anywhere near a medical supply company DME? I know with DS' pulmoaid, I had to have them mail in the compressor for me, but they did indicate they had machines we could rent in the meantime -- 'course that in itself creeped me out as I was concerned with germs/cross contamination and fortunately had a spare. Does your clinic have compressors you could borrow?
