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.

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.

Seems to work fine. Had a minor flood and had it off till things got better. Once room was stable I turned it back on saw the pm2 something was high like 3.x and it brought down pretty quick. Unlike our older ones that run at same speed and don't put into auto because they can wake you up or miss something on TV this I don't think I ever heard run high maybe once. Most of the time it runs low or maybe not at all.
I would recommend this to a friend!

[This review was collected as part of a promotion.] I really enjoy our new Blue Signature Air purifier! It was very easy to set up and link to the app. It is not the lightest and takes up some space, but I love how it can also be used as a small side table, and you can put some small items on top of it. The washable cloth filter is terrific and can be easily removed for washing.
The purifier works very quietly, and I don't notice it most of the time. I love the auto-sense feature( it automatically cleans the air twice daily). We have an open space layout, and this purifier covers all the space in 10-25 minutes!!
Another excellent feature is that the app can track your location, and it can be set up to turn on the cleaning 15 minutes before you get home. Not too many air purifiers offer this. The purifier can be set up to a manual or auto clean and lights up with five different colors to indicate the quality of the air. This purifier would be a great addition to any household.

[This review was collected as part of a promotion.] First, can we acknowledge how stylish this purifier is?
It looks like statement piece that I can’t stop raving about❤️
It’s so easy to use and I can tell you – air quality is definitely better! Zero noise and low maintenance.
Especially since someone is into oil painting.

[This review was collected as part of a promotion.] The Blueair Blue Signature Air Purifier has been a fantastic addition to my home. My living room and kitchen share an open space, so cooking and spice aromas often linger, but thanks to its Airsense technology, it detects them instantly and purifies the air in no time, leaving no trace of odor. I especially like controlling it through the mobile app, which makes the whole process much more convenient. The Auto mode works flawlessly, requiring no effort from me, and runs quietly without any disturbance. I also appreciate the color-coded lights that indicate air quality, and its sleek design fits perfectly in the corner of my living area, adding to the overall aesthetics.

[This review was collected as part of a promotion.] I keep getting more and more impressed by this brand! The quality of filtration is top notch; I live in a highly wooded area, so I really appreciate that it cleans the forest fire smoke and pollen from my home, along with germs and other impurities. The device is sleek and chic while being a powerful tool. It's not very loud, even on the highest setting, and it cleans the air quickly. The odor control is amazing, the air smells fresh even after spicy meals. The app is so convenient and easy to use, and I love that it functions as a table-top! Worth every penny!

Fresh, clean air at home? Totally worth it. 🌬✨

[This review was collected as part of a promotion.] Living in a two-bedroom home with a toddler 👶🏻 means I’m always thinking about the air we breathe. 😮💨
Between cooking smells that linger and dust that sneaks in from outside, the Blueair Blue Signature™ Air Purifier has been a total super duper helper for us. 🥹
It cleans the air in minutes, tackles odors like a champ, and I can literally feel the difference when we walk in the room. I love that it’s quiet at night, smart enough to adjust on its own, and easy to control from my phone. 🤳
