This listing is for a Vornado Evaporative Humidifier plus one brand new filter for it. (NOTE: the box says it contains two filters but there is only one left inside.) This has been a great humidifier, especially in the winter time. It's easy to fill and it has multiple settings for both speed and humidity level. And yes, it works--you can see the blue lights are on in one of the pictures. It could use a little cleaning, but that's about it. The only reason we are selling it is because we upgraded to a larger one. Serious buyers only. Cash only.
