Customer Ratings & Reviews

I bought this air purifier when the air was really bad from fire season. I haven't put it away. It's super quiet, takes little space. I use it to circulate the air and when my downstairs neighbors light up. The pot smell always saturates my space and I'm not a smoker. The air purifier makes a big difference, love it.

I put this in a guest room so I don't monitor its performance that closely. However, it is the perfect size for a small to medium sized bedroom and I trust the Blueair products. It was also very easy to set-up. I actually just unboxed it and handed it to an Airbnb guest who was staying in the room and he set it up in a couple of minutes with no issues.

I have been dealing with overnight allergies for many years. Often waking up feeling dehydrated, a stuffed up nosed, and dry eyes. I have tried humidifiers and other air purifiers with some relief, but not much. Overall, my sleep time is good and normal. Yet the sleep quality has been less than ideal. When researching air purifiers again, I found this product to be highly recommended by multiple testing websites. Also, came to find out the air purifier topped the 'worst' list of one of the well-respected sites I viewed. At any rate, I purchased this purifier feeling that getting a more consistent quality sleep is well worth the price of the purifier. Over the the last 4 days of using this product, I found myself getting a much better quality of sleep. I don't wake feeling dehydrated or stuffed. Also, I am amazed at how quiet this purifier is on it's low setting! If there was no indicator light on the top, you would not know it was on! Overall, I am very pleased with the purchase of this item. I would highly recommend it to anyone is dealing with allergies.

This purifier is very quiet on the low setting. The medium and high settings are a bit on the loud side. But the low setting is perfect for a bedroom. I notice that the air feels cleaner so I assume it’s working. No complaints so far, I do wish the medium and high settings were quieter but it’s fine.

Purchased this during the multiple fires in Northern CA. There was thick, unhealthy haze every where. We ran this night and day in the house. While not quiet at the highest speeds, it was very quiet at the lower settings and it worked great. Price was reasonable. Lots of use were snapping them up. Very happy with the purchase!

We purchased this to help clean up the pollen in the air during the heavy season. Works like a charm and even on full blast, these are rather quiet. The external cover is removable for cleaning. Really decent cleaners for the price. Purchased 3 of these in total.

I have severe allergies that recently became more sensitive due to being immuno-compromised. I.e. swollen eyes and infections that have gone on for 7 months now. I soon realized it was my dog after eliminating a few other factors. I bought this a week after my last flare up a month ago. The eye swelling went away and itchiness (tickling). My dog had to spend the night another 3 weeks into using this. No issues whatsoever! I woke up to him next to me one day and panicked so I started with the lint remover. But there were no issues again. I am convinced now, though I was quite doubtful. Wish the design was sleeker like the Molekule and hand a handle. As one reviewer suggested I open my window in the daytime to refresh the air in my room. I also no longer wake up with dry bloody nose during the winter and needing water throughout the night. My sleep has drastically improved. Prior to owning this I would sleep with my window open even if there were a winter storm.

My son has chronic allergies and this thing is amazing! Within a week we could tell a major difference in his bedroom, the air seemed to feel lighter and crisper. He stopped having coughing attacks in the middle of the night too and on the first setting you can barely even hear it!

I don't know why I didn't buy one of these sooner. I have indoor and outdoor all-season allergies and recently acquired a cat, to which I'm also allergic. I must have gotten used to feeling crummy all the time because I noticed a difference within minutes of turning on this purifier. It's very easy to set up and use and has been running non-stop in my bedroom since I got it. I feel so much better in the morning (unless the cat sleeps in my face all night), and I've noticed I don't sneeze at home at all anymore. I swapped out the blue pre-filter for the gray because I figured it'd be easier to tell how quickly it got dirty. Surprisingly, I didn't notice much trapped in it until about a month of use, but it's nice they included two so you can keep it running while washing one. I keep mine on high, and it doesn't disrupt my sleep at all. (It's nearly silent on low.) Overall, a good purchase, and I'd consider buying the other models for larger spaces.

Perfect white noise, double filter system equal to, but cheaper than, hepa. The only thing I don’t like is that there is no way to turn off the light on it. I much prefer a dark room for sleeping. Is there any solution I wonder.

Good for everyday pollen and dust and minor air particulates. Form and function is great I love the way it’s shaped and cleaning the prefilter is easy enough. Reason why I didn’t give it a 5 star is due to no true HEPA filter. But it’s still easy to use and quite effective for the price.

This is a great air purifier. It is simple in design and works really well. I love the cloth filter that just pulls over the main filter. It comes with two and we swap the out while we clean the other. Highly recommend.

I live in a city that gets dust/sand storms quite frequently and this purifier, on the highest setting, makes it livable to use during one. Just that alone is enough but it works well to stave off allergies too.

Three different speeds, third being the loudest. First two speeds are quiet and you can sleep through the noise, but if you're a light sleeper you may have difficulties with the noise level. Does what the descriptions says, room feels very light and clean.

This item works fantastic! It helps circulate the air in my room and it helps me sleep at night. The filter lasts a pretty good amount of time and it’s really easy to change!

Works decently for my home office but it is rather loud at medium and high settings, and itself has a slight smell. On the plus side very simple setup and it looks nice. I'd give it 3.5 stars out of 5, but since I can't give half stars I'll give it 4.

Great air purifier for my home office. Setup takes a minute or two. It does a great job. I can tell the difference before and after. It comes with two cloth filters. Lowest setting is very quiet. Love it.

It is quiet. I can set the speed and keep it there all night and not be woken by changes in the pitch of the motor speed. It has helped my allergies

Hi, I have to say, this air purifier really made a difference in my apartement. I could notice and feel its presence a few hours after I plugged it. I am looking to equipe each room of my apartment with it to ensure I get the same feeling of pureness everywhere. It has been plugged since I purchased it and nothing to report. Thank you Blueair - keep up the great work! Regards, DV
