Don't let it's small size deceive you into thinking it doesn't work. It's powerful and does an amazing job of cleaning the air!

It's very useful on a desk in an office, in a bathroom or other small room even in a car!  It is easy to charge and the battery lasts for several hours. I really noticed the difference with my allergies when running this purifier. 

Very nice quality and great price point for this hard working little machine .
My only complaint is while the low setting is almost silent the high is a little loud, especially if you are going to be sitting by it using the phone.
