Blueair Classic 680i Review


We used the air purifier on our office premises and tested its abilities for more than a month. It removed impurities from the polluted air. Using the Blueair app, we were able to see the differences.

The machine is not enough silent, you can feel the noise. It was able to effectively stop different types of odors from food smell to some other stinks. We found it really useful to remove odors and air impurities.
