Getting me most from your Blueair System
The Blueair system is easy to use. Make sure your unit is the right size for your room, and change the
filters according to the recommended filter replacement schedule. Remember that, just as air condi-
tioners and heaters have limits to the volume of air they can cool or heat, every air purification system
has limits to the volume of air it can clean. Follow these common-sense guidelines.
Close Your Windows
You wouldn’t throw open your windows on a hot summer day and expect your air conditioner to
work efficiently, because you can feel the hot air coming in and the cool air going out. Even though
you can’t see the contaminated air coming in and the clean air going out, the same logic applies to
your air purifier.
Close Your Doors
Just as you might seal off part of your house on a cold winter night to keep your heater working more
efficiently, seal off the room in which your system is working for best results.
Run Your System 24 hours per Day
For the best results, run your Blueair unit 24 hours a day, 7 days a week. Round-the-clock operation
ensures that a continuous supply of clean, filtered air constantly circulates throughout the room.
Blueair systems are designed for phenomenally low power usage. In fact, it costs about the same to
power a Blueair air purifier as it does to power a single light bulb, depending on the unit and the op-
erating speed.
