BlueAir Replacement Filter:

Replace Blueair filters at least once every six (6) months In order to maintain the high performance level you expect from Blueair, we recommend filter replacement twice a year. Why so often? The amount and type of indoor air pollution can vary dramatically from environment to environment. Some manufacturers claim an exceptionally long filter life for their units--some as long as 5 years! At Blueair, we tell you how often filters need to be changed in the real world, not under best-case conditions in a laboratory setting. Clearly, replacing filters every 6 months increases the maintenance cost of your Blueair system. However, we believe you would rather know up front what it takes to keep your indoor air clean and healthy. Without regular filter replacement, your air cleaner is operating at only a small percentage of optimum performance.
