I like this device! It is quiet and non disruptive, and it also is pretty small so it can be tucked away in a corner. I like the scent pod concept a lot, I wish the scent was different as it's not for me. I had blown out a candle and then turned the machine on, and the percentage on the side of the machine went down to reflect the poorer air quality which was kind of cool to see. I don't know how effective it really is because I'm not sure how to measure air quality, but I like the device and it is easy to use.
