    I noticed an almost immediate difference in air quality after I placed this unit in my bedroom. It takes the dust particles out of the air very well.

    This is one of the more highly rated air purifiers -- and for good reason. With its auto mode, turn it on and it'll sense the air and clean it up. Easy enough.

    The unit works great. Less odor from liter box. I find that the air is fresher. The unit is quiet and efficient. Also I like that you can sign up for auto ship for the filter.

    These seem to be a pretty good. I use it in my office, which is a small space. I can feel the air moving around a little bit and my allergies have been a bit better. It's pretty quite too, which is a bonus while I'me working.

    Best air purifier I've ever owned!

    The difference when I walk into my house every day after work is amazing, It's literally a smack of fresh air in my face the second I step through the door. So simple, but does everything you need it too. People also overlook the fact that this is one of the, if not the lowest power consuming air purifier on the market. The auto air quality sensor is really awesome and it picks up on aerosols, air quality changes, and cooking smoke/smells really well. It only takes a few seconds for it to ramp up and start filtering.

    This is a very nice air purifier. Fashionable, while also clearly doing its job. My only misgiving is that it doesn't have a remote control like another air purifier that I own does. That would really come in handy.

    I live in an old apartment that gets dusty from the drafty windows. I also have a cat. Both the cat and I have allergies. Since using these purifiers, I have a lot less of all of the above. I keep them on auto and they’re quiet most of the time. They have cranked up a couple of times as the air required which wasn’t too loud and wasn’t for long. I’m pleased with this purchase so far.

    Works extremely well and given the power it's actually quite silent. I like how it automatically adjusts to compensate for changes in air quality.

    Great volume for how unassuming it looks. Fits great and practically becomes invisible, and makes very little noise.

    Over Priced for what you get..

    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

    Very nice air purifier, bigger than I thought it would be but that's ok. The auto feature is nice as it adjusts fan speed based on pollution. I blew out a candle near by and the purifier detected the smoke and kicked up the fan speed. The nighttime mode is a great feature as it turns off the light but I actually perfer a fan noise at night so it would be nice to have the fan in fast without the light. Overall great product, wish it was a little cheaper, don't forget the cost of filters.

    This thing works really well with cleaning the air. When it’s runs on its max setting it’s a little loud but not enough for me to move out of my bedroom when I sleep. However light on it is bright, especially at night. I never took the time to see if it can be turned off. I just have the machine facing the wall. Overall I’m happy with it and the design is very nice. Definitely not an eye sore
