After months of research, I decided to buy the Pure 211+ Auto because of the rave reviews and the high CADR rating. As a person with bad dust and pollen allergies, I wasn't going to compromise, and felt like the price was justified if the product was truly *that* good. I followed the set up instructions very carefully, made sure nothing is blocking the 4 sides of the purifier, kept my windows closed, etc. (worth noting that my space is smaller than 550sq ft), But after a month of using it all I can say is that this product does not live up to the standards. Just a waste of money, unfortunately.
The product itself is well built, and attractive and I've noticed that it detects when I'm cooking and works hard to clear the smoke. I just wish that it did the same for dust and pollen.
