It is working. But i am not sure how good it is. I bought Phillips air purifier on black Friday for the same price with this one which works much better.

Cleans the air quiet operation easy to understand adjustments of time fan etc

Light weight easy to move around Can be set for night mode - silent- no noise Easy time settings Very easy to use all settings I recommend

Excellent product does what it's spose to do and does it well ,and very quiet on night mode Excellent purchase

I had a prickly, itchy problem that I put down to pet dander... the problem disappeared almost overnight! Thank you, Breville!
