General FAQs

To ensure maximum performance, an air purifier should run 24 hours a day, seven days a week. For that reason, Blueair devices are developed with low power consumption in mind, making sure environmental impact – as well as cost of ownership – is as low as possible. The low energy consumption is made possible thanks to the HEPASilent™ technology, which combines two types of particle filtration, electrostatic and mechanical. Due to this combination, Blueair’s air purifiers are able to use less dense filters, resulting in a high Clean Air Delivery Rate (CADR) while keeping the noise levels and the energy consumption down.

Blueair products are certified by Energy Star, a globally recognized program of the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy. In addition to being Energy Star certified, Blueair products are also tested according to local energy efficiency programs such as MEPS (Minimum Energy Performance Standards) in Korea and GB/T 18801-2015 in China.

Particles, bacteria and viruses

Blueair air purifiers are designed to remove both ultra-fine and coarser particle pollutants from the air. Most particle pollutants are natural or come from the incomplete burning of fossil fuels. The most common natural pollutants are dust, pollen, mold, pet allergens, viruses and bacteria. The pollutants from incomplete burning of fossil fuels come from vehicle motors, industrial processes and power plants.

Volatile Organic Compounds (VOCs)

VOCs are gaseous organic chemicals found in both outdoor and indoor air. “Volatile” means that a compound easily evaporates at normal temperatures and pressures. VOC sources are widely used as ingredients in household products. Paints, varnishes and wax all contain organic solvents, as do many cleanings, disinfecting, cosmetic, degreasing and hobby products. The irritating gases may play a role in many illnesses, from respiratory disease to chemical sensitivity.

A quick reduction of gaseous pollutants is best achieved by the filters with activated carbon, such as SmokeStop™, DualProtection, MultiSmokeStop and the Particle and Carbon filters.

Certifications & Ratings
The higher the CADR test numbers, the better the unit’s overall ability to clean indoor air. For example, if an air purifier has a CADR of 388 for tobacco smoke particles, it will reduce smoke particle levels to the same concentration as would be achieved by adding 380 cubic feet of 100% clean air per minute.
The Clean Air Delivery Rate (CADR) is an established standard defined by the independent Association of Home Appliance Manufacturers (AHAM) in the U.S.
Blueair’s HEPASilent™ technology is what makes Blueair air purifiers almost silent. In this technology, pioneered by Blueair, electrostatic filtration first makes airborne particles easier to trap by giving them a negative electrical charge. This negative charge makes the particles adhere to the polypropylene fibers in the filter more easily, which allows the use of a less dense filter, so more air can be pushed through with less noise and less energy.
Wildfire smoke

If evacuation is not necessary, stay at home and keep your indoor air as clean as possible. Close doors, windows, air intake vents, and fireplace dampers. Designate a room that can be closed off from outside air.  Set your ventilation system to recirculate and put your air purifiers to the highest level.4,6 

We recommend our Blue Pure 211+ Auto, Classic 605 or 680i, and our HealthProtect 7410i and 7470i models for removal of wildfire pollutants. Click here for more information.  

Be sure to use an air purifier certified by the Association of Home Appliance Manufacturers (AHAM) and look for the Clean Air Delivery Rate (CADR), which indicates the unit’s ability to reduce smoke, dust, and pollen particles. Install a carbon-based filter in your air purifier to reduce gases and odors caused by the smoke. 

Wildfire smoke travels far and wide. Satellite images from past California wildfires have shown show smoke traveling with the jet stream across the United States from California to Washington D.C8. Breathing air pollution affects everyone. Even if you’re healthy, breathing in fine particles could cause acute lower respiratory tract irritations or infections.
