What are the possible reasons?

1. Small deviations between the sensors’ readings is normal because PM sensors in Blueair air purifiers use different measurement technology depending on the model

2. ​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: Contact the Blueair Customer Support

Possible causes

​​​​​​​1.The air is clean. PM are expected to be set to 0 (<1) or to show blue on the device if the air is clean.

2. The ​sensor module filter is clogged with dust. This may happen if the device has been running for a long time in a polluted environment​.

Actions

• Confirm that the sensor is functioning by turning off the air purifier, or by applying dust to the sensor (for example: by shaking dusty cloth next to the sensor). You should see a peak in PM values after this action. ​
• Try vacuuming the sensor module filter and test again​

If above actions do not change the status, contact the Blueair Customer Support.

"My app shows high levels of tVOCs – My air purifier shows bad air quality"

• tVOC peaks are normal and expected to happen temporarily. For tVOC levels to decrease, the air purifier should be used according to recommendations
• The Blueair app can help find the source of pollution by checking the air quality history: check the peaks’ date and try to find out what may have happened at those moments​
• Try to ventilate the room for 10-15 minutes and see if the tVOC level lowers. If it does lower, it might mean that the sensor was detecting a gas that the air purifier cannot remove (presence of human, animal)
• If the source of pollution cannot be found: Restart the device and expose it to clean air for 15 minutes, for instance by opening a window when the outdoor air quality is the best.

If any of the actions above did not help, contact Blueair Customer Support.

• Remote control of the air purifier even when you are not in the room

• Creation of schedules to have the air purifier run at specific times and modes

• Activation of the Automode and Night mode of the air purifier

• Clean Air ETA (Estimated Time of Arrival) indication

• Child lock to prevent usage of the air purifier

• Indoor air quality monitoring of PM1, PM2.5, PM10 (PM1 and PM10 are not available for all air purifiers), tVOCs, temperature and humidity. Indoor air quality monitoring is only available for devices with integrated sensors.

• Outdoor air quality monitoring of the PM2.5, PM10, carbon monoxide, nitrogen dioxide, ozone, etc. around the world in real time.

• Outdoor/Indoor comparison view

Note: Your air purifier needs to be WiFi-enabled to be able to connect it to the Blueair app.

Go to your app store and search for the app called "Blueair". The app is available on Google Play, Apple Store and Huawei store.

Once you have downloaded the Blueair app on your smartphone,

1. Plug in the air purifier

2. Open the Blueair app and follow the instructions to connect the air purifier to the app

Note: Your air purifier needs to be WiFi-enabled to be able to connect to the Blueair app.

You only need the WiFi or mobile data when using the Blueair app. Some models of Blueair air purifiers require Bluetooth and WiFi during the pairing of the app for the very first time. It ensures a quick and easy onboarding. After that, the air purifier only needs to be connected to the local WiFi network provided by the local router. Your smartphone does not need to be connected to the same internet connection as the air purifier (except during the onboarding, for certain models). Note: Car air purifiers connect via Bluetooth. For more information, see the Cabin FAQs.

You can download the Blueair app on any phone (iOS 12 and higher and Android 5 and higher) or tablet. The Blueair app is not available on computers.

Open the Blueair app and follow the instructions to create an account. All you need is an email address.

The Blueair app updates automatically or if you manually download the update. If you want to make sure you have the latest app version, delete the app and re-install it from the app store. Your devices will remain paired to your account even if you delete the app. Your devices will automatically appear in the new version of the app.

Particulate Matter (PM)

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

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

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

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

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, gasoline, wood, coal, natural gas, paints, glues

Yes. You can add all your Blueair devices (if they are WiFi enabled) to your account in the Blueair app. When pairing the air purifier with the Blueair app for the first time, both the device and the smartphone need to be connected to the same Wi-Fi network.

We use the BreezoMeter Air Quality Index (AQI) for outdoor air quality measurements. The data is sent from the nearest BreezoMeter station. More information about BreezoMeter: https://breezometer.com/faq/ 

The MAC address can be found on a label on the air purifier (usually located underneath the device). You can also see the MAC address in the Blueair app, in the Product Settings page.

Open the Blueair app and go to the Product Settings to delete an air purifier from the app.

Air purifier with integrated sensors give air quality indication on the device, even if not connected.

Add your air purifier to the Blueair app again to change WiFi network.

The air purifier will make sure that it connects to a 2.4Ghz network by itself.
