You may already know this.....but....those humidifiers need constant care and cleaning to keep bacteria from growing on the innter parts. I prefer to boil water daily on the stove so that I can easily clean the pot. I believe, and hope, it keeps just enough humidity in my home. If those humidifiers grow bacteria inside it doesn't help our BE, as you know. I really need to get a humidity testing guage/tester and now that I write this and hear myself....I'm getting the guage.!
