Great little bedroom air purifier definitely works well for a small bedroom maybe about 400 ft.² or up to 500 ft.². Nothing larger definitely works well and picks up any kitchen smoke or any air quality very fast. The only thing I would say is the actual filters are about $50 I think and I think it’s a little too small. I think an air purifier should be able to pull in more air to clean it more efficiently.

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!

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

My partner and I have wanted to get an air purifier for some time now, our roommates have cats, the previous residents were smokers, and our room gets dusty and very stuffy. I was able to get this Dustmagnet one on sale. I love this little thing so far. It’s only been a couple days to be fair but I’ve already noticed a difference in the freshness and crispness of the air. My partner and I have it in our bedroom. And I don’t know if it was just older reviews and the product has been improved or I’m missing something… but I have no issues with the sound. I expected it to sound like a fan. It is like realllllly quiet. We have it on auto and I can only hear it if I really pay attention. Even on its full setting it is simply a nice white noise and quieter than a fan in my opinion. On the app you can change the setting, monitor the air quality, and even turn down the LED indicator lights or turn them off entirely. I also very much enjoy its style, it gives me mid century modern vibes which I love. Time will tell about how it works long term but so far I’m very excited about it. In the video, I go through the different settings and there is little if any background noise. Level 2 and 3 seem to be significantly louder than any of them. I keep mine on auto full time and it’s virtually silent. The picture shows how I have my filters placed, the only thing I would change about this product is to make it super super clear in the instruction manual which direction they go in.

My main objective was to reduce dust and dander particles in the air, and I have seen a noticeable improvement. It's quiet and I like that I can turn off the led lights at night. My cat also really enjoys sitting on it, but then he learned he could change the fan speed or turn it off, so I also really like that there's a child lock that deactivates the control buttons on the unit (and just use the app). Like others, I was confused about the direction of the filters. I contacted customer service and was sent a diagram showing that the top filter should have the white accordion folds facing up, and the bottom filter should have the black charcoal side facing up. Although the diagram also noted that the filter direction will not affect efficiency of the unit.

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!

Smaller than expected. Cheaply made. Functional. Expensive. Very expensive. Intake through the underside and top each with a prefilter mesh layer. Filters are outrageously overpriced. App is slick but telemetry for data collection for selling my anonymized data is sad. Blue air is a solid recognized reliable brand and as a result they'll take all they can from their consumer base that helped them succeed.

After conducting extensive research on air purifiers, I finally made a decision between two options and went with the Blue. As someone who works from home, having a clean and healthy environment is crucial, and this product delivers on that front. Despite being located in my living room, it effectively circulates all the air in my two-bedroom home in just an hour, ensuring that the air is free of smoke and other pollutants. As someone who smokes, I am especially impressed with how well the Blue works to eliminate smoke from my home. Though it can get a bit loud at times, I appreciate how it reminds me to quit the habit. When I am not smoking, it gradually becomes quieter until it is virtually silent, which is a nice touch. After seven months of use, the Blue has exceeded my expectations. Though the accompanying app indicated that the filters still had 16% life left, I decided to replace them sooner and was glad I did. Overall, I am thrilled with this purchase and only wish I had made it sooner. I highly recommend this excellent product and give it five stars.
