The app notifies you every time the firmware in your device is being updated.

During the update, you must keep your air purifier connected to the Wi-Fi to have the firmware update complete. It is imperative you do not unplug the air purifier from the wall during any firmware updates.

The update should take a few minutes. Please do not disconnect your unit during the update!

If the update takes longer than a few minutes, your Wi-Fi signal might be a bit too weak at that time.

If so, unplug the Blueair device and plug it in again.

Then, go to your app and remove your device from the list (swipe left on the device).

Add your device in the Blueair Friend app again.

To get a better internet signal, you can try to place the device closer to the Wi-Fi router and ensure that the connection is not busy with other connected devices or downloads.

If you have access to a faster Wi-Fi network that supports 2.4 GHz, try to connect the device that that network.

To use auto mode, your air purifier must have built-in sensors, or be connected to the Blueair Aware standalone air quality monitor. Check the user manual for your air purifier in our Customer Support section. Your air purifier model is shown on a label at the bottom of your unit.

If your air purifier has built-in sensors, start auto mode manually by pressing the auto mode button on the unit display. On Classic units, you find the display under the lid on the top of the unit. If your air purifier is connected to the app, start auto mode from the fan control screen: Fan speed 0 -> 1 -> 2 -> 3 -> auto mode.

If your air purifier doesn't have built-in sensors, and you use an Aware air quality monitor, set the auto mode from the app. The air purifier and the Aware must be paired.

To pair your air purifier and the Aware:

1. Log in to your Blueair Friend app and tap the air purifier in the device list.

2. Select the linking symbol.

3. Select the Aware monitor you want to link to your air purifier:

  • If you have already added a Blueair Aware air quality monitor to your account, select the Aware from the list of available devices.
  • If you haven’t yet added the Aware to your account, select Add Blueair Aware and follow the steps in the app. When the Aware is added, select the Aware from the list of available devices.

4. A pop-up in the app asks if you want to activate auto mode directly. You can accept and enable the auto mode immediately, or at any time from the fan control screen: Fan speed 0 -> 1 -> 2 -> 3 -> auto mode.

Auto mode is triggered by the level of particles (PM) and/or gases (tVOC). The trigger options depend on your filter type:

Particle filter: Auto mode is only triggered from Particles values. SmokeStop™ filter (combined filter with Carbon): Auto mode can be triggered from Particles values or both Particles and gases values.

You set the auto mode trigger(s) in the device information screen in the Blueair Friend app.

If the night mode is not working, the time zone settings in your mobile phone might be incorrect. Go to the Settings menu in your phone and set the time zone so that it corresponds to your current location.

The sensors measure

  • the concentration of Particulate Matters (PM2,5) in the air
  • the concentration of Volatile Organic Compounds (VOCs) in the air
  • the air temperature
  • the humidity in the air

Particulate Matters (PM2.5)

PM2.5 are air pollutants with a diameter of 2.5 microns (micrometers or µm) or less. They are also known as ‘fine particulate matter'. Common PM2.5 sources are car traffic, industrial plants, metal processing, cleaning fluids, beauty products, candles, cooking and smoking.

Volatile Organic Compounds (VOCs)

VOCs are different organic chemicals, that are emitted as gases from certain solids or liquids. They include both human-made and natural chemical compounds. A total VOC (tVOC) sensor detects such gases and summarizes them into one level. No individual gas is tracked. Both harmful and harmless VOCs are detected.

Examples of families of substances that the VOC sensor detects:

  • Aldehydes (formaldehyde, acetaldehyde, acrolein).
  • Hydrocarbons (toluene, benzene, undecane, xylene, naphthalene, butane, styrene, ethylbenzene, propane, kerosene).
  • Amines (ammonia derivatives), alcohols (ethanol etc), ketones (acetone, methylethylketone (MEK), butanone, butanedione).
  • Esters (butyl acetate).
  • Carbon monoxide, hydrogen, acrylamide, organic acids.

Common VOCs sources are building materials (paint and varnish), furniture, printers, cleaning products, air fresheners, laundry detergent, glue, paint, perfume, repellent, scented candles etc.

People and animals also release VOCs when they breathe, perspire or digest. These VOCs are not dangerous for humans if the room is properly ventilated. The Blueair filters are not designed to remove these VOCs. You easily get rid of them if you open the windows every day for 5-10 minutes.

A high tVOC value may result from a high level from one single compound or it may be a collection of low compound levels from a chemical ‘mix’. Our filters remove most of the VOCs that the sensors detect, but not all of them. If you get high VOCs that don't go down with ventilation, investigate the potential source of pollution. Check your app to spot the moment when the VOCs started to increase. Then try to relate it to an event that occurred at that time (new furniture, use of a fireplace, cooking, big cleaning)? If you need help to understand the values, please contact the place where you bought the unit or Blueair directly.

Air temperature and humidity

The sensors detect water stagnation, water damages, humid surfaces and warm environments. These factors can encourage the growth of mold, bacteria and allergens, such as house dust mites. The common recommendation of humidity is between 30-65%. VOCs tend to evaporate more with a higher temperature.

If you are using an air purifier with sensors, you have the option to set the purifier on auto mode, via the app or on the unit directly, to trigger the airflow speeds automatically according to pollution levels.

If your air purifier automatically runs on the highest speed level, it means that the concentration of VOCs and/or particles in the room have increased and requires faster air cleaning. You can choose via the app if you want the auto mode to trigger on particle levels or particle and gas levels (Tap the information details (‘i’)).

Your air purifier should gradually lower the airflow speed as soon as the air in the room is clean again.

What does it mean if the air purifier continues running on high speed?

Most of the time, it means that some dust is clogged on the filter or on the sensors. Here is what you can do:

  • Make sure you have replaced the filter in the last 6 months.
  • Make sure that the auto mode settings in the app are adapted to your type of filter (if you are using a Particle filter, the auto mode trigger in the app should be set to ‘Particles’ only. If you are using a carbon filter, the auto mode trigger should be set on both ‘Particles' and 'Gases’).
  • Check that no dust or any item is blocking the inlet and outlet grids of the air purifier. Vacuum the air purifier from the outside. Don’t forget to vacuum where the sensors are located. The sensors are two circular arrays of holes on the side or at the bottom of the unit.
  • Open a window and air out the room. If high levels of VOC (gases) are causing the full speed, the room might be filled with a gas which cannot be removed by the air purifier (tVOC sensors can sense thousands of different gases, including harmless ones which cannot all be removed by the air purifiers).
  • If auto mode and child lock are activated, deactivate them from the app. Try to change the fan speed from the app or manually.
  • If you are using an air purifier from E-series (models 270E, 450E, 550E, 650E etc.).
  • Use a can of compressed air (like the one you use for keyboards) to clean the sensor area. From the outside, give the sensor area a couple of 3 seconds blasts.
  • The sensors are two circular arrays of holes on the side of the LED display, one will be arranged like a flower; the other, a circle.
  • If cleaning the sensor area doesn't help, reset the software on your air purifier. This resets the filter timer and the sensor: link to how to reset the E-series settings.

If you need any help, do not hesitate to contact the place where you bought the unit or Blueair directly.

Some deviation between the sensors is normal as every sensor is different.

Many factors need to be considered, such as the airflow intake, uniqueness of each sensor, calibration effects, the historical diagrams of your app (depending on when you have refreshed the page).

Every sensor can have slight performance variations, and put together they deliver a slightly different output figure.

Troubleshooting

If your air purifier doesn’t switch on, try this:  

- Most Blueair models have a detachable plug that can slip out when you move the unit.  Place the unit on its side and push the plug back into the socket at the bottom of the unit. 

-Make sure that the filter of your air purifier is correctly inserted and that the door of the air purifier is closed.   

-Unplug the unit from the electrical outlet and plug it back in again. 

-Plug the unit into another electrical outlet. 

-Check the power cord. If it is damaged in any way, unplug it immediately. Contact your local Blueair team to learn about getting a replacement or repair.

-Make sure that you have selected a speed level to start cleaning the air.   

-If you are using a remote control, make sure that the battery is charged. If it isn’t, replace the battery.

If your air purifier still doesn't start, please contact the retailer where you bought the unit.


Make sure that you removed the plastic cover from the filter (not applicable to all models and filters). 

Make sure that nothing blocks the air inlet and outlet. 

Make sure that no object or dust is clogged around the filter. If there is, remove the filter and clean the purifier with a vacuum cleaner. 

Remove the filter(s) to see if it is causing the noise: 

1. Turn off your air purifier and unplug it. 

2. Remove the filter(s). 

3. Plug in the unit and turn it on. If the noise disappears, install a new filter. If the noise is still there, please contact the retailer where you bought the air purifier. They will help you according to their warranty conditions




First few times you use your air purifier:
As any new device, an air purifier can release a ’newness’ smell. Don't worry, this odor is not dangerous or toxic! Run your air purifier non-stop for a few days and odor should dissipate.

For optimal use, keep the air purifier on at all times. It uses less energy than a low-energy light bulb.

Time to change the filter:
A dirty filter can release a dusty smell. Filters absorb odors from, for example, cooking. To avoid this, always replace the filter when indicated.

Your device has lost its Wi-Fi connection temporarily. 

If you haven’t changed any the Wi-Fi settings on your router, the device should be able to reconnect by itself within a few minutes. 

If necessary, try the following troubleshooting tips to reconnect the device:

  -  If you changed a Wi-Fi setting on your router, you must update your app with these settings. Tap ‘+’ in the top right corner of the app and re-add your device.

  - Unplug and plug the router. 

  -  Make sure that VPN is off and that you are not using Firewalls (for more information about, check below the Wi-Fi network requirements: 'What Wi-Fi does Blueair smart products support?').

  -  Place the device closer to the router. 

  -  Check to see if the Wi-Fi is busy with other devices.


What Wi-Fi does your Blueair product support?

2.4 GHz standard Wi-Fi access point (b, g or n).    

All standard signal encryptions: WEP, WPA, WPA2, TKIP, AES.     

Un-encrypted wireless connections (i.e. Open) Please note: Professional versions of the protocols which require a certificate are not supported. This can be the case for company networks.     

Captive portals are not supported. This is when you need to enter a username and password to access Internet, such as in airports or public places.    

Access point that broadcasts multiple SSIDs networks or on multiple channels simultaneously may create problems of data packets being lost. This is especially the case in pairing products to the app.     

Make sure that no firewall blocks outgoing connections (blocking inbound connections is OK) or any restrictions on protocols such as http/https or sockets.
