An attic has been converted into a bedroom and it's very uncomfortable to sleep in, the air is very dry. I bought a humidifier but it didn't come with instructions. This may be a silly question but I want to make sure: how do I use the humidifier? I filled it with water and plugged it in. Nothing has happened after 30 minutes. A sticker on it says that if it doesn't work the first time to add salt to the water and to refer to the (non-existing) instructions. On the box it says warm mist vaporizer, are vaporizers the same thing as a humidifiers?
EDIT: I added salt and now it's going a little bit, hardly any steam is coming out of it, should there be more?
