I have three humidifyers in my home. One in our family room, one in the main part of the house and one in our bedroom.

You can get a humidifyer at Walgreens or probably any drug store that are pretty cheap. That is the kind we have in our bedroom. What I don't like about those is that they are on and that is it. My other two have a off on that is triggered by the % humidity.

Something else that is pretty cheap is a vaporizor. I also have a vaporizer in the bedroom for when my sinus problems flare up.
