Our house is so dusty all the time. I bought this for our bedroom and it’s worked wonders! The quality is amazing, it’s very sleek and modern. Super quiet and at night I put it on night mode which dims the control lights. I know I will be buying more for other rooms. You will not regret this purchase!

I got this air purifier specifically to remove cooking odors, however, it doesn’t remove them at all. I’m very disappointed, as they advertise it as removing odor, but it doesn’t. I have even placed the purifier in my tiny NYC kitchen in hopes it would work, but it didn’t. Have been using the unit for a week but we’ll return it.
Thank you for sharing this feedback. We are sorry to hear the Dust Magnet did not meet your expectations for cooking odor removal, especially in a small kitchen space. Odor performance can depend on factors like airflow and filter type, and we appreciate you giving it time to try. We have reached out to you directly to better understand your setup and help with next steps.
