How much area or space will my new Vornado humidify?
As a rule of thumb, Vornado’s Model 30 humidifier will effectively humidify a single room in an average home. The Model 40 humidifier can effectively humidify several rooms when strategically placed in close proximity to the rooms so that the humidity can be dispersed between the rooms. Keep in mind, there are very few portable humidifiers that can humidify an entire home. To truly achieve the desired level of humidity, you will likely need additional units.
