Best Buy Customer Reviews
A Best Buy!

A thank you goes out to Best Buy for stocking this item. I previously purchased this very proficient Blueair Air Cleaner from Best Buy three years ago however, I was only able to locate replacement filters from the manufacturer which are pricey. I ordered two of these replacment filters from Best Buy and will definitely continue using Best Buy for future purchases.

Great Air Purification
Posted by: ccislandguy from: Corpus Christi, TX on
The BlueAir unit (400 series) works really great. You know you are breathing clean air, HOWEVER you can't find the replacement filters. They charge $80 bucks at BlueAir and even though Best Buy offers them at a much better price, they NEVER have them in stock.
