Review on Purifier Personal Office Bedroom Circulation by Sam Bell

This is a small and portable device, equivalent to a large cereal bowl. Definitely works well, as soon as my husband lights up he realizes the air quality has changed and immediately blushes. I'm glad it plugs into a real outlet. I've only used it on the lowest settings (so far), so there's almost no noise. I want to change the temperature setting, it is programmed in Celsius not Fahrenheit.
