Some "3-in-1" tools, appliances etc. are kind of a joke, but not this.  I legit had each of these items in the same room at one point.  Three things.  Three plugs.  Three pieces running electricity and taking space.  Now it's all in one sweet little package.

I trust that its an effective purifier and it is definitely an effective heater and fan.  It's a nice looking design, super easy to use, and I can't imagine any other features I would need.  Definitely try it.
