How can I get the most from my Blueair system?

The Blueair system is easy to use. Start by choosing the right size unit for your room, and replace the filter at the recommended 6-month intervals. Remember that just as air conditioners 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 commonsense 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, too. 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. This is especially important for people using a Blueair system to ease nighttime asthma or allergy attacks.
• Run your system 24 hours per day. Blueair systems are designed for phenomenally low power usage, so you can run the system 24/7 without a jump in electricity consumption. In fact, it costs about the same to power one of our air purification units as it does to power a single light bulb: between 15 and 120 watts, depending on the unit and the operating speed.
• If visible "fluff" builds up on the outside of the air intake grids, as it can in dustier parts of the world, simply vacuum it away or wipe clean with a damp cloth. The air intake grid is designed in part to intercept very large particles before they enter the system, thereby prolonging the life of the filter. The 402 units may also be vacuumed on the inside, if necessary, while the side panels are open for filter replacement.
