Improper cleaning maybe. People get Legionnaire's from shitty motel rooms with AC units that don't drain correctly, so it isn't that farfetched for a closed loop respirator full of moisture to harbor nasty pathogens all the same.
Yes, you can get infections from poorly maintained CPAPs (or respirators -- are those a scam, too?) but that's not going to spread to your whole family.
