You need this!

I have used other air purifiers in the past, and this one far exceeded my expectations. The first thing I checked was to see if they were work easily to find replacement filters, because with other big brand ones they stopped making the filters. Making my unit worthless after spending all that money. Blue air has plenty of filters available on their website. You can even get a subscription. The air purifier is quiet, even on the highest setting. It jumps right in and turns on when i'm frying foods, make it odor like bacon. My air just smells cleaner. I used to get a lot of dust on my entertainment center and in tables. This device has made much more of a difference than any of the other ones.I have tried. I swear my house looked like halloween all the time and I cleaned. Overall, this has been my favorite air purifier. I highly recommend everybody get this one.
I would recommend this to a friend!

love the quietness, but not sure how well its working. I still have allergy issues with runny nose and itchy eyes, even though this model is supposed to cover a wider area.
No, I would not recommend this to a friend.

Gets the job done!

[This review was collected as part of a promotion.] Blue Signature is larger than I expected, but it actually turned out to be the perfect size for our open-concept living/ dining/ kitchen area. The top is flat and sturdy and doubles as a side table or nightstand when used in a large bedroom. The modern design and light neutral gray color work beautifully with our new existing home décor.
The unit is easy to use and can be controlled directly from the touchscreen, which magically lights up with a simple touch. It’s super convenient for quick setting changes. That said, I actually prefer using the app—it offers more advanced options, including setting a schedule.
Performance-wise, it’s whisper quiet on the lowest setting and in night mode, but on the highest setting, it sounds more like a strong fan. Since our air quality is usually excellent, the purifier doesn’t need to run very often. The only exception is when we’re cooking, especially with butter—the air quality rating jumps from “excellent” to “very polluted,” but the unit quickly kicks in and purifies the air in no time.
One small issue is that dust bunnies tend to collect around the lower part of the unit. I’m planning to purchase some legs to elevate it slightly to prevent this from happening.

[This review was collected as part of a promotion.] This is definitely a great air purifier. I love it. There are several modes of operation and it really cleans the air of unpleasant odors and pollutants. Its design is simply incredible! It is very easy, convenient and quick to use! It is also almost silent.

Solid air purifier with nice design

The Blue Signature is a well-designed air purifier that blends seamlessly into my home. It’s effective at maintaining clean air day to day and I find it helps a lot while cooking as our vent hood doesn't capture all the fumes. Additionally, it runs fairly quiet, even at higher fan speeds. The app is easy to use and adds a lot of convenience, especially with scheduling. Overall, I’ve been happy with its performance. 4.5/5

Compact yet powerful!

[This review was collected as part of a promotion.] We have two cats, a dog and two kids in our house so odors are common in our home 😅 add in allergies and asthma and fresh air is a must so when I saw that BlueAir not only has a 7 stage filtration system but can clean our whole house’s air in just an hour, I knew it was the air purifier for me!
The app controlling feature makes it so convenient to use and the compact size makes it easy to blend in to our home decor. I can’t recommend this purifier enough 🙌🏼

I am extremely happy with my unit. It quickly gets rid of unpleasant odors and helps when pollen counts are high. It is easy to move to where I need it to be and quickly takes care of filtering out smells in the room that it is in.
