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.!

@raney Diligent airway clearance will help with the deep mucus removal. It took time to build up and it will take time to get out. Mucinex 1200mg tablet twice day and 7% saline via nebulizer twice day. Albuterol before nebulizer often helps especially in asthmatics.
