Wonderful Design
I love the efficiency and effectiveness of the Airmega 450 design. Nice variety of settings. It cleans the air quickly and quietly. I love that the filter is covered in a pre filter that traps dust and particles. I have a smoke intensive filter, which filters everything else by the way.

Love this purifier
[This review was collected as part of a promotion.] This is bigger than I expected, but it arrived at the perfect time. I really needed to freshen the air in my home and get rid of a lingering smell — and it worked so quickly! It also blows out air, which helps cool down the room while it purifies. I'm really impressed with how well it works.

Quiet and energy efficient!
[This review was collected as part of a promotion.] Was pleasantly surprised with how quiet this air purifier is, I've never used one before so not sure how it compares but I can't hear it at all in the eco mode! I like that it has many different features/modes to help with energy efficiency.
