Must have

[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.

I have 4 different Blueair purifiers in my home. This one is my largest unit and does a fantastic job. Even the cat likes it.
I would 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 unit functions exactly as promised. Great form factor, quiet operation unless the air is particularly bad. It is definitely more sensitive to air quality changes than other products we've used and has been impressively effective in reducing pet odors when we put it next to our cat's litter box. Exceptional product.
I would recommend this to a friend!

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.

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.
