Clean Air - Nothing Compares
Living in a fire ravaged area in California, The Blueair 311 has been a "LifeSaver" insofar as keeping the quality of healthy air in my home. It's quiet, dissipates the smoky nature of air resulting from chimney use and environmental burns. I highly recommend Blueair. Christmas will include this unit for my daughterVerified purchase: YesCondition: New

Breath the Breeze
We are trying to find the less/cheap maintenance and easy to operate air purifier kind of system.. Blue Air 311 Auto is delivering it. How do we know if it is really working? we saw this youtube video where the expert compares 5-6 air purifiers with Blue Air and Dyson in it... the winner is Blue Air, great results with cheaper price.. Great value of money and you can immediately feels and smells fresh air in the room. We sleeps better, I cough/sneeze seldom due to dust allergy.. When you have stinky foods, Blue will purifier your room in a short second! Love the product and definitely recommended specially if you like to cook spicy and stinky foods/meals..Verified purchase: YesCondition: Pre-owned

Super quiet on any mode!! Love it
I've always wanted a purifier to improve air in my room & the house... It's a BIG boy for what Blueair call it " medium-sized" from my perspective of what i though it's size would be... You would think the fan is off with how quiet it is on any speed mode(1, 2, 3 or auto)Verified purchase: YesCondition: New

Would not buy it again
It is quiet on all but the highest setting. It just doesn't seem to make much difference in air quality. Also, the cord is too short to make various placements possible. Instructions say extension cords cannot be used. I would not buy it again.Verified purchase: YesCondition: New

Blueair air filter is wonderful.
The Blueair does just what it is suppose to do, it has cut down on the dust and particles in the air which make it easier to breathe at night.Verified purchase: YesCondition: Pre-owned
