Which Blueair unit is the best for me?
That's simple. It's a matter of room size.
Each Blueair model uses HEPASilent™ filtration technology to achieve 99.97% efficiency at 0.1 micron. But filter performance is only part of the picture. Your air purifier must also be able to process the volume of air in the room where it operates. You need only compare the size of your room to the room size capacities listed below.
Our room size recommendations are based on testing by the Association of Home Appliance Manufacturers (AHAM), an independent industry organization that rates air cleaners for overall performance. Choose the system that matches your room size. All room sizes assume an 8-foot (2.4 meter) ceiling; if your ceilings are higher, choose the system that matches the next larger room size.
