Hello and thanks for reading. Has anyone experience with the use of humidifiers. Diagnosed as an adult with Asthma last March, could coincide with moving house. However, in an attempt to help my wife purchased humidifiers which I use at night in the bedroom. I have a couple of concerns. 1. Is there any research on their use and ethicality. 2. They are damnably difficult to clean and was wondering if they could harbour bacteria as water does remain within the units often for several days.
Anybody any knowledge please.
