Smoke generated by forest fires is comprised of water vapor, fine particles, and gases. The exact composition of wildfire smoke varies depending on temperature, wind, and the materials burning, but gases commonly include carbon monoxide, carbon dioxide, nitrogen oxide and volatile organic compounds (VOCs). The fine particles often referred to as PM 2.5, or particulate matter of 2.5 micrometers in diameter, in smoke are most harmful to health.
Our recommendation is to run your air purifier continuously to ensure efficient air circulation and low pollutant levels in your room. Blueair air purifiers are energy efficient and very silent on the lowest speed level so you can keep them on and enjoy breathing clean air!

Blueair air purifiers are intended to be used only in the country or area where they have been purchased. This ensures that local laws and regulations are followed. Follow this link to find the closest store.

HEPASilent™ filters are made of polypropylene, which is hydrophobic and thereby prevents bacterial growth. HEPASilent™ filters should be recycled as plastics according to national regulations.

Before making your choice make sure to ask yourself these questions:

1. Why do I need an air purifier?

Blueair offers different types of air purifiers and different types of HEPASilent™ filters. When choosing a Blueair air purifier, first consider your needs.

To help with allergies/asthma, to capture dust mites, airborne mold particles, pet dander, bacteria, viruses and microplastics, use the HEPASilent™ Particle filter or the combination HEPASilent™ filters (Particle + Carbon).

To remove smoke, odors, traffic pollution, chemicals and other types of gaseous pollutants or VOCs, use a HEPASilent™ filter with activated carbon. The HEPASilent™ filters with activated carbon are efficient at removing both particles (dust, allergens, etc.) and gasses. The availability of the filters might differ depending on the country of purchase. Please contact your local Blueair reseller for more information.

2. In what room will I place my air purifier?

For optimal results, your air purifier should be placed in the room where you spend the most time, or where the air quality is the worst. Every Blueair air purifier is intended to be used within a certain room size to ensure a high reduction of pollutants. When selecting a model, first measure your room. An AHAM verified Blueair air purifier delivers five Air Changes per Hour, based on recommended room size, ensuring the air quality in a room is excellent. If the air purifier is placed in a larger room than it is recommended for, the number of Air Changes per Hour (ACH) will be reduced. If the air purifier is used in a room smaller than its recommended size, the number of Air Changes per Hour will be increased.

3. How smart do I want my air purifier to be?

Some air purifiers are smarter than others! The Blue series, for example, is designed to be easy to use with one single button to control the different speed levels. The Classic series, in comparison, offers a variety of different smart functionalities. These features include the ability to control the air purifier via the Blueair Friend app, smart sensors that will monitor the pollution levels in your room, auto mode, and the ability to connect to Alexa and IFTTT automation. Make sure to check what features your air purifier comes with before making your final purchase.

Your air purifier is most efficient when all the doors and windows are shut.

Does this mean you should never open a window when your air purifier is running?

No. Ventilation plays an important part in the improvement of your indoor air quality. We advise you to ventilate your home every day by opening the windows for at least 10 minutes to let in some new air. If the outdoor air is highly polluted, try ventilating when the outdoor air quality is at its best, by checking the outdoor air quality levels in your Blueair Friend app. During this temporary ventilation, you can leave your air purifier on. Once you close the window, the air purifier will lower the indoor pollutant levels.

Thanks to the unique design of Blueair filters and the Blueair HEPASilent™ technology, Blueair is able to deliver a high Clean Air Delivery Rate (CADR) while maintaining low noise and energy consumption. We have innovated our filters to have a large surface area preventing premature clogging to ensure a longer lifespan. Each of our HEPASilent™ filters is unique. One is not better than another. The different types of filters we offer have been designed to meet different needs.

Particle HEPASilent™ filters

Designed for maximum removal of airborne particles, the Particle HEPASilent filters are the perfect choice for removing pollutants such as pollen dust, pet dander, mold spores, viruses and bacteria, down to 0.1 micron in size.

The Particle HEPASilent filters are not designed to remove gasses (VOCs) from the air. For VOC removal the combined HEPASilent filter (Particle filter + activated Carbon) will do the trick!

Combined HEPASilent™ filters (Particle + activated Carbon)

Particle and Carbon filters, SmokeStop™ filters, MultiSmokeStop filters and DualProtection filters remove particles, microplastics, odors, VOCs, ozone and gases.

The combination filters catch every airborne contaminant down to 0.1 micron: pollen, dust, pet dander, mold spores, viruses, allergens and bacteria. The active carbon is also effective against smoke, odors, gases and VOCs. And like all other parts in your Blueair air purifier, the material is 100% recyclable.

Where in my home?

For optimal results, your air purifier should be placed in the room where you spend the most time, or where the air quality is the worst.

If your asthma or your allergies keep you awake at night, running your air purifier in your bedroom sounds like the best choice.

If you wish to get rid of specific odors (smoke or kitchen odors), keep the air purifier in the room where the odor is the strongest.

Where in the room?

The two main factors to consider when deciding where to place your air purifier is the air flow and air circulation. Where in the room would the air purifier create the best air circulation?

Air purifiers have an inlet where the polluted air is drawn in and filtered, and an outlet where clean air is pushed out. Place the air purifier where the air can circulate freely in, out, and around the unit, away from walls, furniture and other objects that may stop the air flow.

Recommendations for the placement of your air purifier:

  • Place it at least 10 cm/4 inches away from any potential obstacles
  • Avoid corners
  • Place the air purifier as close as possible to the pollution source

Purification technology

Though the HEPASilent™ technology, uses electrostatic filtration to capture and remove particles from indoor air, Blueair products should not be associated with dangerous indoor ozone. Dangerous indoor ozone can be formed by air cleaning techniques based solely on ionization technology, or by systems using ozone to clean the air. We understand the serious concern involving the negative effects of ozone. Blueair takes this matter seriously and ensures that our air purifiers are safe and do not add ozone to the room.

All Blueair air purifiers conform to international and local ozone emission requirements in EU/CE, US/EPA & ARB, China/GB.

Does my air purifier reduce ozone in my indoor air?

Yes! All Blueair air purifiers have been tested for their ability to reduce ozone concentrations in indoor air. The results confirm that all Blueair air purifiers reduce ozone concentrations, especially when used with a filter containing activated carbon. Ozone reducing capabilities have been tested by the SP Technical Research Institute of Sweden since 2016. The Blueair Classic 600 series models with activated carbon filters reduce ozone in indoor air by 95%.

The indoor air quality thresholds are based on several regulatory values recommended by the United States Environment Protection Agency (US EPA) and the World Health Organization (WHO). For outdoor ambient air, the Blueair Friend app uses the thresholds from the US EPA Air Quality Index (AQI).

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.

Check the following topics to learn more about the effects of Blueair air purifiers against smoke and VOCs.

Air purifiers for tobacco smoke.

Air purifiers for VOCs, odors and gases.

Contamination from airborne traffic pollution is divided into two types: exhaust particulates and gasses, such as nitrogen dioxide (NO2). To remove both types of airborne contamination from traffic pollution, make sure to use a HEPASilent™ filter with activated carbon. Filters with activated carbon are the only kind of filter that will adsorb the harmful gases and keep them locked away.

Wildfire information

In California, the air quality during wildfires has been known to exceed WHO standards for safe air by 60 times, when pollution concentration in the air has been as high as 1,500 micrograms per cubic meter.1 Breathing in wildfire smoke, made up of toxic gases and fine particles (PM 2.5), poses an increased health risk since these fine particles can enter the lungs and travel through the bloodstream  inducing inflammation.2 It can exacerbate conditions those with pre-existing respiratory and cardiovascular disease can also cause acute lower respiratory tract infections for healthy individuals.3,5  Depending on the degree of smoke exposure, health effects may range from reduced lung function to heart and lung diseases.3,5

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 

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.

Ozone information

Blueair has conducted ongoing independent testing to ensure our air purifiers do not release harmful levels of ozone. All Blueair air purifiers are tested in accordance with UL Standard 867 demonstrating ozone emission levels far below the mandated California Air Resource Board (CARB) ozone emissions limit of less than 50 parts per billion (ppb). All Blueair air purifiers are CARB certified. 

In 2021, Blueair air purifiers* have also achieved Zero Ozone Verification, one of the most stringent ozone emissions standards available, by independent testing lab Intertek. Products with this designation meet or exceed all other nationally recognized and certification programs, emitting ozone concentrations of 5 parts per billion (ppb) or less.    

See more information about the Zero Ozone Verification: https://www.intertek.com/sustainability/zero-ozone/ 

Blueair’s HEPASilent technology uses a combination of electrostatic and mechanical filtration to capture and remove particles from the indoor air and should not be associated with air-cleaning techniques based on only ionization, or with systems using ozone to clean the air. Our HEPASilent™ technology is unique in that it uses mechanical filtration to draw in polluted air into the air purifier and then specifically and strategically uses an ionizer to electrostatically charge particles inside the air purifier, allowing particles to better cling to the filter media in the unit, which in turn increases the air purifier’s filtration efficiency and overall performance.  Blueair’s electrostatic charge technology is fundamentally different and should not be confused with technologies that use only ionization as a means of directly creating and releasing ions or ozone, because our technology also utilizes filter media to capture pollutants. An air ionization device, corona discharge or ozone generator air cleaners rely solely on techniques that produce and release ions into the space or uses ionization to intentionally emit ozone.   

  • Our ozone emissions are rigorously tested to ensure they do not exceed any harmful levels. 

  • All Blueair air purifiers conform to international and local ozone emission requirements in EU/CE, US/EPA & ARB, China/GB. 

  • Blueair air purifiers have also been tested to reduce ozone in the air. Our ozone reduction tests have shown lower ozone concentrations in the air directly after passing through Blueair’s air purifiers and filters than the ozone concentrations in the surrounding air.  

Yes! Blueair air purifiers have been third-party tested for their ability to reduce ozone concentrations in indoor air. The results show ozone concentrations in the air, directly after passing through Blueair’s air purifiers and filters, to be lower than the ozone concentrations in the surrounding air.
