Didn't realize how small it actually is
This is very small!  Now, I put this in my bedroom as I wanted to see if it would bother me at night and whether or not it would work to clean the air.  I do have sinus issues and for some reason, at night, my nose will clog up and then I'll get up, blow my nose, lay back down, breathe easy for a while, then clog up again.  I am assuming I have some dust or other allergen in the air that's bothering me.  After plugging this in and setting it where I wanted on the table next to my bed, the sound is very quiet and for several nights in a row, while using this air purifier, I did find that my nose didn't clog up nor did I have to get up to blow my nose during the night.  Does that mean this machine is working?  I would have to say yes since it is the only thing that changed in my room for those nights.  I will try it in the kitchen the next time I burn something and create some lingering smoke in the room.  I'm very curious to see if it works like their video shows.  Based on its use in my bedroom, I would say this air purifier works very well.
