I bought six of these filters in Dec 08 and they are fake. They have different markings on them from the original BlueAir filters. The filter media is also oriented up-to-down instead of left-to-right. The width is 1/8-inch shorter so there is a gap when you put them into the machines. And hold the filter up to a light and you can see through the filter!!! There is no carbon in them. DO NOT BUY THESE - RIP OFF!!!
