Ask any physician what is best for you when it comes to vaporizers and humidifiers and it will be difficult to get an answer. They both have many benefits while the negative aspects are few. Their firm belief is that it is the moisture that relieves the symptoms, and in that respect they would get everyone’s approval. Not only do they keep nasal passages moist, they work wonders on dry skin. During cold and flu season, they add considerable creature comfort to the afflicted.
Of course safety is an issue because the vaporizer uses heat to produce warm air. The humidifier uses heat as well but it also cools the air before it reaches your nasal cavities and the amount of heat used is much lower. Personal likes and dislikes will factor into the equation of which one to use. If your home is full of young children, the humidifier may bew best for now.
