Fresher air in a medium to large room, fast

The Blueair Blue Signature SP3i air purifier clears a room of around 498 square feet in about 12.5 minutes and can cover up to 2,250 square feet within the hour, so you feel the difference in air quality soon after you turn it on.

Seven stages of HEPA filtration capture 99.97% of airborne particles, including dust, pollen and pet dander, while a built-in VOC sensor picks up on compounds and odours you cannot see or smell. Its OdorFence technology lifts far more odour than a standard filter manages, which makes a real difference in kitchens, living rooms or anywhere pets spend time. A dynamic display adjusts on its own to show how the air is tracking, so you always know it is doing its job rather than just running in the background.

Running on just 36 watts, the Blueair Signature SP3i is gentle on power while it works, and a longer-lasting filter design means fewer replacements to keep track of. Pair it with the Blueair app to check air quality and change settings from your phone, and the light grey finish sits comfortably in most living spaces.
