Low Energy Consumption - Blueair is among the first to earn the energy star designation for air purifiers, a program developed in the United States and sponsored by the U.S. Environmental Protection Agency (EPA) and the U.S. department of Energy. All models exceed energy star's minimum energy efficiency guidelines.* Easy to Use & Maintain - Plug it in and select the speed setting. Blueair works so quietly, at first you may find yourself pondering if it's turned on. Blueair filters require no weekly additives or filter washing and the grills and powder-coated steel exterior are easy to wipe clean. Industry High CADR - CADR was developed by the Association of Home Appliance Manufacturers (AHAM) in the United States, to help consumers worldwide determine how well an air cleaner reduces airborne pollutants such as tobacco smoke, dust and pollen - by indicating the volume of filtered air delivered. The higher the Clean Air Delivery Rate (CADR), the faster the unit filters the air. CADR takes into account: ? the size of the particle removed ? what percentage of particles are removed ? the volume of air actually moving through the system When the particle size and filter efficiency of any two air cleaners are the same (as they often are), CADR is the key to choosing the more effective system. To ensure accuracy and fairness, CADR testing is performed only through AHAM, an independent industry organization. CADR test results are recognized as accurate and impartial by the U.S. Environmental Protection Agency. Blueair has achieved CADR ratings that are among the highest in the industry.
