This Queenty Desktop Air Purifier is fantastic for my use. It was easy to install and set up. It starts automatically once it's plugged in. I enjoy the nice night light and the two speed settings are good to have. My husband likes to smoke a cigar once in a while. He sits by his laptop on the dining room table smokes his cigar while playing a card game. This portable air purifier is perfect for this. The oscillating air from the air purifier gives a constitent breeze of pure clean air to the area. It's nice that it comes with a HEPA filter and USB power cord. Even though there isn't an adaptor incuded it doesn't matter. I have a few of them already. It's quiet and we can tell it is working to clear the smoke from the air. I originally got this for my room but may have to get another since he likes it. I would certainly recommend this air purifier for a small area. Using it on a desk, table top or night stand is a perfect spot for it.
