Great little purifier
This is small and portable, equivalent to a super sized cereal bowl. It definitely works well, as soon as my husband lights up to smoke, it recognizes the air quality has changed and immediately turns red.<br />I'm glad it plugs into an actual wall socket. I have only used it on the lowest setting (so far) so the noise is next to nothing. I do wish I could change the temperature setting, it's programmed to Celsius instead of Fahrenheit.
