YANKO DESIGN
“I tested it with kitchen odors while cooking, and within about 20 minutes of running the air purifier, I could smell little to nothing. I find that astonishing. I've used other air purifiers before, but this one does the trick.”

Seems to work well and is quiet and seems efficient. We are using in our open floor plan 1,500 sq foot condo.

Our neighbor burn wood next-door and it caused our house to smell like smoke really bad. The blue air purifier light turned red and noticed the air quality indoors was bad. Within an hour, the air quality was good again and we could breathe once more. We love it so much, we are thinking about getting one for the bedroom as well.

I have had several different models, and this one by far beats all of those—love it!

I purchases two SPI3's for my computer room to replace an Alen 45I and a Winix T830. The SPI3's have substantially higher CADR performance than either of those units. They also measure VOCs as well as PM2.5 which neither of those two units do. The filter is also technologically advanced being a 7 stage HEPAsilent filter filtering down to .1 microns and having the ability to filter out VOCs. I also like that the prefilter is removable and washable. I purchased two additional prefilters so that I can swap the prefilters when the used filters are being washed so I am not down as the filters are drying. I also purchased the wooden base to elevate the filters and add a custom look to the filters. Blueair, simply put, makes the best air purifiers on the market today having won various best-in-class awards for their products. I've already recommended the product to other members and friends of my family.

Arrived one week before the smoke from the forest fires in the north came to the city. Woke up to orange skies and were at good/ excellent air quality while many of our neighbors had to use multiple air purifiers to stay safe or come over because they did not have any type of air purifier. The Blueair signature is quiet and efficient. Really appreciate the app for monitoring as well.
