Understanding pollutant levels

PM stands for particulate matter, which is the term for a mixture of solid particles and liquid droplets found in the air. Particles have different sizes:

• PM1 are particles with a diameter of 1 micrometer and smaller. Example of PM1 (from 0.3 to 1 micrometer): Bacteria, suspended dust, house dust, animal dander, smog, tobacco smoke, soot.

• PM2.5 are particles with a diameter of 2.5 micrometers and smaller (human hair is Approximately 70 micrometers in diameter). Example of PM2.5: house dust, animal dander, bacteria, cooking oil smoke, grease, smog, fly ash, settling dust.

• PM10 are particles with diameter of 10 micrometers and smaller. Examples of PM10: pollen, dust (settling dust, cement dust), mold spores.


Total Volatile Organic Compounds (tVOCs):

Volatile organic compounds (VOCs) are gases and odors emitted from different chemicals. VOCs can be found in the air in your home; they are released by cleaning products, cosmetics, carpeting, furniture, air fresheners and many other consumer products.


Total Volatile Organic Compounds (tVOC) is the total concentration of all VOCs in the air. It is used to give an indication of the VOC levels.


Common VOCs sources: Gasoline, industrial chemical, solvents, burning fuel, wood, coal, natural gas, paints, glues.

We use the BreezoMeter Air Quality Index (AQI) and pollutants monitoring for outdoor air quality measurements. The data is sent from the nearest BreezoMeter station. You may find more information about BreezoMeter directly on their website: https://breezometer.com/faq/
Open the Blueair App and you will see the outdoor air quality information (AQI) on top of the home screen. Set your location by inputting your local address to get your local air quality information. You can also add additional locations, like where you work, the location of friends and family members, or even locations all around the work and follow the outdoor AQI for those via the Blueair App.
The air purifier can still track indoor air quality levels on the panel even when not connected to the WiFi. In the App, the air quality measurement will not be shown if the air purifier is offline.

1. Open the Blueair App and you will see the outdoor air quality history on top left of the graph. 

2. Click on “Now” and you will be able to choose between seeing daily, weekly, or monthly aggregated AQI data on the graph.

Control your unit

If the air purifier disconnects from the WiFi, the Welcome Home triggers will not get activated.

Try to re-connect your air purifier to the Blueair App and re-enable the Welcome Home once the air purifier is connected

The always-on precise location access provides an estimate of the device's location that is as accurate as possible, usually within about 50 meters (160 feet) and sometimes as accurate as within 3 meters (10 feet). The service will work in dense urban areas as well.

With the use of geofencing technology, the app calculates your arrival within 15 minutes based on the selected type of transportation and your position. 

If you do not travel outside of the Welcome Home radius, then the Welcome Home feature will not be activated. The size of the radius is determined based on the selected type of transportation (walk, bike, car, etc.). ​​​​​​​ 

The air purifier will run on Auto Mode.
No. The air purifier will go into Standby when you leave home and into Auto Mode when you return. To minimize any disturbances, the Welcome Home feature will switch to the Night Mode (instead of Auto Mode) if you arrive home between 9 pm and 8 am.
• Adjust the fan speed, Auto Mode, Night Mode of your air purifier • Create schedules to run the air purifier • Set “Welcome Home” to turn on your air purifier when you approach home.
You can create schedules in the Blueair App to have the air purifier run at certain times and modes, based on your needs and habits. You'll be able to select the time that the air purifier goes into a specific mode, as well as a fan speed, LED brightness and the day(s) of operation. After every scheduling event the Blueair Purifier will return to the state where it was prior to scheduling. You can even activate a schedule when the device is in Standby mode. In this case the unit will return to Standby mode after the scheduling event is over. Please note the air purifier will turn off any ongoing schedule if any speed or mode is changed manually - either on the app or on the physical device. Your air purifier should be online (connected to the Wi-Fi) to trigger the scheduled mode.
Welcome Home is currently supported for one person per Blueair App account. We are looking into developing the use of the feature to multiple users in the coming release.
If someone changes the settings on the air purifier, it will overwrite the Standby mode set via Welcome Home. Then, when the person with the Welcome Home feature on their phone arrives home, the device will switch to Auto Mode. ​​​​​​
You can create multiple schedules per device, for instance: - You can set up a schedule to run your purifier on Auto mode during working hours and on workdays. - You can add a second schedule and send the purifier to Night mode every night from 10 pm until 6 am. Each schedule can be individually named.

Welcome Home is a smart and convenient feature for energy-saving using a a geofencing technology that allows your air purifier to go into standby mode when you leave your home and turns back on as you approach home, ensuring your home is filled with clean air when you arrive.  

Blueair doesn’t collect or store the actual location of your mobile device, neither does Blueair constantly track your location. Instead Blueair keeps on monitoring your 'Home' location and triggers actions when you enter or exit your home perimeter

All HealthProtect™ and DustMagnet™ air purifier models can enable the Welcome Home feature. 

1. Download the Blueair App and create a Blueair App account.

This section is for all Blueair products who have an integrated air quality sensors for Particulate Matter, such as the following models: Protect, DustMagnet™, Classic-i, Blue Auto.


Why is the air purifier detecting high levels of Particulate Matter (PM)? • Particulate Matter (PM) peaks are normal and expected to happen temporarily, even when the air is of good quality because your air purifier’s sensors react each time the air purifier is in contact with airborne particles. • Pollution from outside coming in from open windows or ventilation may also cause high PM levels.


The levels of PM should decrease with the use of the air purifier and with ventilation. Examples of PM sources: candles, smoke, cooking, incense, fireplace, accumulated dust, unfiltered vacuum cleaner, pollen, pets, etc.


How to decrease the particulate matter (PM) levels and improve your indoor air quality? • Make sure that the air purifier is used in an adapted room size with closed windows and doors. • Set the highest speed of the air purifier temporarily or use the Auto Mode (not available with all models). • Ventilate the room temporarily.


What to do if the PM levels do not decrease?


• Try to find the pollution source. If the PM values are constantly high, the indoor air might be polluted. If your air purifier has the WiFi feature, the Blueair app can help find the source of pollution. Open the Blueair app, add your air purifier and check the air quality history: check the peaks’ date and try to think of what can have happened at those moments. • Test the air purifier in a smaller room. Test the PM sensor by placing the unit in a small room running at full speed with all windows and doors (and ventilation if possible) closed. • Clean the sensors. If the PM levels are constantly very high, there might be accumulated dust on the sensor giving a false indication. Vacuum the outside of the air purifier, especially the air inlets, outlets, and the inlet for the air quality sensor. Power off the unit before vacuuming. See sensor care and maintenance FAQ. and user manual.


If the above actions did not help, please contact our Blueair Customer Support teams to investigate further.

Small deviations between the sensors’ readings are normal because PM sensors in Blueair air purifiers use different measurement technology - depending on the Purifier model. Large differences between sensor readings may happen if the sensors are clogged with dust. Try to vacuum the sensor from the outside. The PM values should decrease shortly after the vacuuming. If the issue remains, please contact your Blueair Customer Support.

This section is for all Blueair products who have an integrated air quality indicator for total Volatile Compounds such as the following models:
Protect and Classic-i.


Why is the air purifier detecting high levels of tVOCs (totale Volatile Organic Compounds)?
The tVOC* levels will increase each time the air purifier detects VOCs** in the air. If the air purifier's tVOC sensor is always reading high, the indoor air might be temporarily polluted with gaseous pollutants.


Why do tVOC levels seem to increase at night in my bedroom?
It is common to see higher levels of tVOCs in bedrooms or generally in any room with human presence. The reason is that the human body produces different gasses and VOCs, such as nitrogen, hydrogen, carbon dioxide, oxygen, and methane. Those "human-made" gases cannot all be removed by air purifiers. Simply ventilate the room regularly to let in fresh air and remove those gasses.


How to reduce VOCs?
• Use the air purifier in a room adapted to its size
• Use a filter with activated carbon
• Run your air purifier continuously
• Avoid excessive use of perfumed substances, cleaning products, or other VOC contributors
• Ventilate the room regularly and see if the tVOC level lowers. If the level of tVOC lower when the windows are open and stay at the same level when windows are closed, then the device is detecting a gas that cannot be removed by the air purifier.
• It is common to see higher levels of tVOCs in bedrooms at night or generally in any room with human presence. Gasses produced by humans or animals are not all removed by air purifiers. Ventilation, in addition of air purification will help you remove those gasses.
• Use the Blueair app to find the source of pollution by checking the air quality history: check the peaks’ date and think of what can have happened at those moments.
• If the source of pollution cannot be found, you can reset the air quality sensors by:
• Restarting the device and expose it to clean air, for instance by opening a window at night, when the outdoor air quality is at its best (15 min approx).
• If any of the actions above did not help, contact your Blueair Customer Support.


*Total Volatile Organic Compounds (tVOC) is the sum of VOC concentrations. It is used to give an indication of the VOC levels.


**Volatile organic compounds (VOCs) are gases and odors emitted from different chemicals. VOCs can be found within the air in your home; they are released by cleaning products, cosmetics, carpeting, furniture, air fresheners and many other consumer products.
