Great product

These filters were terrible. (And this is probably only the 2nd review I've ever bothered to write on Amazon -- that's how bad they were). Trusted previous reviews and purchased these to save some money. They were posted in a flimsy plastic sleeve and were crimped and compromised on arrival. The outer filter has been inadequately superglued to the carbon filter and were coming apart in various places. When I tried to fit onto the blueair 411, the carbon filter crumbled and tore. I realise they are a "bargain" when compared to branded BlueAir filter -- however can't see the point of owning a great filtration device to then 'skimp' on inadequate filters. Returned immediately and will cough up the necessary funds to get a quality filter that actually fits and does the job it's intended to do.

Perfect Fit: These filters are designed to fit the specified Blueair models perfectly, ensuring optimal performance. Easy Installation: The installation process was simple and quick, taking only a few minutes to replace the old filters. Effective Performance: The filters work efficiently, maintaining the air purifier's high standards of air quality. I highly recommend them to anyone needing replacement filters for their Blueair purifier.

Exactly as listed.
