    My family and I have been using SmartAir purifiers and filters for the past three years. Super affordable and super effective. 赞!

    Nice service, good product at this price. In just 3 days my filter looks black as it’s hazardous AQI. Seems to be workingv great.

    Received in Korea within one or two weeks (can’t really remember; it was 9 months ago). Like David said, it was received as advertised. Works very well. Only drawback compared to more expensive models is that after a few months you can see a circle on the air purifier (matching the fan output) getting dirtier and dirtier. Guess that means it’s working…

    Great product. Exactly as advertised. Highly recommended! Keeps the air clean at a super low cost without taking up much space or waking me up while I sleep. Perfect if you have a small apartment or a bedroom.
