This air filter is a miracle worker! We have a problem of neighboring cigarette smoke and very strong cooking odors coming in thorugh shared walls and running this machine eliminated the issue! I even tried a competing air filter and it failed compared to Blueair. I've bought four of these now, for bedrooms, livingn room and the original offensive mud room with shared walls. In addition, we have very polluted air quality where I live - from pollens to factories and again, this air filter really cleans up our air! Thank you Blueair!

I bought two for my small cottage in N. California. I have cats (dander) a fireplace (smoke) and live by a creek under the redwoods (mold). Wow. After the first night running both units, I woke up WITHOUT a stuffy nose, and no sneezing! And happy I upgraded and bought the units with the PM display! This thing is so sensitive that when on "auto" mode, it will kick in when I light scented candles or if my smoker friend walks by it after having a cigarette outside. Makes you really aware of toxins in your air.

Love my machine (280i), except it won't allow me to sync my WiFi/phone, probably because I'm not close to my WiFi on a lower floor and other end of the house. That would allow me to put on auto. But the quality of air in my bedroom is so much improved. I'm sleeping better; waking up without congestion. Even my companion, who sleeps here sometimes, sleeps better and wakes up refreshed. He even snores less! It's so quiet on low speed for sleep, but medium isn't bad. Sometimes I run it on high during the day to really clean the air. My companion unpacked and set it up for me. I'm very tiny. But, I'm pretty sure someone of normal size could do it alone.

This is my 3rd one owning . I simply love the product, it does a great job at keeping my house filled with clean air. Especially during fire season (I live in California) . The machine is very quiet and works great with wifi

Great product. Did research & this was rated at the top. I am near a fire & it has helped with the air quality in my home. My allergies have gone way down. This the 3rd Blueair air purifier I have bought within 3 months.

I have had the BlueAir Classic 280i for about 10 days as replacement for an old Honeywell HEPA air purifier. The 280i produces much less noise than the Honeywell and purifies the air much faster. Overall, I am pleased, but a disappointment is two substantial sources of light pollution that posed problems for use in my master bedroom. The first light pollution problem is the large bright blue LED on the side. I understand that this can be dimmed by using a wireless application, but I think that poses security problems. However, I overcame this first LED problem but sticking a refrigerator magnet over the LED. The second light pollution problem is not so easily solved, though it is not as severe. The control panel has six bright blue LEDs which are "covered" by a lid. Unfortunately, poor design of the lid allows the bright blue light to escape in two horizontal slits between the hinges. The slits are right next to the air flow, so they cannot easily be covered. The light produced is bright enough to travel some distance and bounce off objects, especially light or glossy objects (and mirrors), creating bedroom light pollution. Numerous scientific studies show that sleep can be disturbed by bedroom light pollution, so this limits the desirability of the 280i for use in the bedroom, though I have managed to position the 280i to limit the amount of light emitted through the slits in the lid. Purchasers who plan to use the 280 in the bedroom should be aware of this concern. Otherwise it is a the best air purifier out of the four that I have owned in the past.

We had originally bought the blue 211+ and returned it because we found it too bulky, too loud, the light on the front was distracting in our bedroom, and the outer pre-filter looked dingy almost immediately. But it performed significantly better than the molekule purifier we also have so we knew we wanted to stick with this brand. They made returning the other air purifier super easy and we have been very happy with the Classic 280i. This air purifier is incredibly effective and we really appreciate the more detailed readings we get on the app. We know exactly what is polluting our air and can see how quickly the purifier amends it. The unit itself is more streamlined and fades into our decor. It's also significantly quieter than both the blue 211+ we previously had and the molekule unit. This is a solid air purifier, from a company with a stellar track record, and you can feel confident that you are purchasing a quality machine.

this system is thin, and the design looks good in our bedroom. the system is very quiet and works very good.

Quiet, fan bearings last for years, As far as i can tell the internals have not been cheapened, As with nearly every other company.

Look no more, Blueair is the best there is in the market. I had a Classic 500 series and added this for my office. Loving it so far!
