Good quality

Gift for my daughter, she’s very happy with it’s performance.

So far so good. The night setting is very quiet. Works quickly on kitchen smells from cooking. Overall dust level in house noticeably better after a few weeks of use (we have two cats). Bought another one!

The Only Air Purifier I'll Ever Buy—A Dust Destroyer with a Hyper-Responsive Sensor! My apartment was a dust magnet. Despite having an air purifier running in the bedroom and regularly swapping out the central HVAC filter every month, dust would settle so quickly that surfaces needed dusting by midweek. It was an exhausting, never-ending battle. Since installing this Blueair unit, my dusting frequency has plummeted from every few days to nearly once every two weeks. The unit cleans the ambient air so thoroughly that the particulate matter simply isn't there to settle anymore. This massive reduction in indoor dust alone made it worth every penny. While the long-term results are incredible, the real fun (and proof of performance) is watching the air quality sensor in action. This sensor is not sluggish or reactive—it is instantaneous and hyper-responsive, proving how quickly our indoor air quality can change. It's like having a little clean-air sentinel that instantly detects invisible threats. I’m consistently impressed by its ability to pick up: * Cooking Incidents: Searing a steak, or using the air fryer immediately triggers the sensor, which jumps to the red warning level and ramps up the fan speed to clear the air before the smell even reaches the next room. * Aerosols and Vaping: Spraying deodorant, hairspray, or using an aerosol cleaning product causes an instant spike and response. Similarly, it right away picks up if anyone is vaping, instantly activating to neutralize the particles. * Other Disturbances: Even something as simple as using a high-powered blow dryer, which kicks up hidden dust and heated particles, is enough to get this machine working overtime. The combination of the sensor's hair-trigger responsiveness and the long-term efficiency in removing dust makes this air purifier an absolutely essential home appliance. It doesn't just manage air pollution; it aggressively eradicates it. If you want superior air quality and a demonstrable reduction in house dust, look no further. Highly, highly recommended for any home, especially apartments!

As described, so far seems efficient but need to update if dust levels do not improve. Nice looking, quality materials.

i rewieng I'm reviewing this product after couple month of used because i had been thoroughly looking for something for my mother's room to help filter out dust and odors, this device really delivers the air in the room has improved tremendously- the odors are gone, and it very easy to her to use. it doesn't take up much space and runs quietly. I'm very happy with this purchase!! .
