The name Blueair is well-known to anyone who lives in or visits a household with respiratory problems. The company’s Classic 680i purifier offers one highly effective filter that can be replaced by customer preference between two different types – this choice gives users more versatility than most other models on the market!

The Particle Filter/ SmokeStop filter helps you breathe easier by capturing 99.97% of pollutants such as pollen, dust, and pet dander while filtering out viruses or bacteria down to 0.1 microns! If that isn’t enough for your allergies (which it probably will be), then pay more on top with an additional layer that is made up primarily of activated carbon – this extra step really does make all the difference when fighting off those pesky particles.

Blueair Classic 680i’s SmokeStop filter, which has a highly porous structure of activated carbon, is used to combat pollutants and scents.

We put the Blueair Classic 680i’s air filter to work for three months, and we can vouch that it is naturally antibacterial. Also, it will dissuade bacteria and mold from developing— which are two allergens and asthma’s primary causes.

Blueair technology is named HEPASilent for a reason. The Blueair 680i runs in a quiet mode with noise levels so low, you’ll barely hear it running—louder than rustling leaves on the ground.

Most people with allergies or asthma don’t bother with the Smart features on high-end air purifiers like the Blueair Classic 680i, but this unit can be operated by Alexa.
