    Ever since we set this up, our allergies have subsided considerably. We’ll worth the money for us. Highly recommend.

    Unit extremely quiet, compact and unnoticeable, and shows noticeable difference in moving air. Dust accumulation on furniture and desk showed improvement in a room size of 20x20 within 24 hours.

    Love it! Filters air quietly, and well. On high is a little noisy but all air filters are. The high setting filters air very quickly!

    There is nothing that justifies the price. Says it takes pollen an dust out of the air but thats if it close to the fan/filter an settles by it, i still see dust settling on items within the day less then 5 feet from the purifier, This basically only purifies odors. This purifier is okay but for a full price tag of $250. it is way over priced for what you get, even the sale price of $200 is still over priced, i say it should be around $75 for what you get. This is basically a fan sitting on a soft plastic base which is the filter and thats it. There is not really any tech thats into other then 3 fan speeds, an the the auto setting to ramp up the speed that detects bad quality air... So if you have a cat litter box or wanna deodorize other smells in the air, then this is it but still way over priced. Their is other purifiers that are as pricey or even more but they atleast have 5 or 6 different features to some what justify the price your paying

      Hi there! All of our purifiers use Blueair's patented HEPASilent™ technology, which captures at least 99.97% of airborne particles down to 0.1 microns in size, removes germs and delivers especially high performance and efficiency by combining electrostatic and mechanical filtration technologies. Our purifiers are rigorously tested and have their CADR (Clean Air Delivery Rate) verified by AHAM, The Association of Home Appliances, an independent testing organization considered to be the gold standard for determining the safety and performance of air purifiers. Provided that your 311 Auto is in a space of the appropriate square footage or smaller, it will absolutely be effective in removing airborne pollutants from your home's air. blueair
