1. Wi-Fi and Blueair Friend App
With the new Wi-Fi capabilities of the Blueair 280i air purifier, it is possible to pair your Blueair air purifier to your smartphone via your home network. To do this, you will have to download the ‘Blueair Friend App’ from the App Store or Google Play to your iOS or Android smartphone. With the Blueair Friend App installed, you will be able to adjust airflow, change LED intensity, child lock the unit and activate or deactivate night mode. In addition, you are also able to check the units Wi-Fi status, monitor PM2.5, VOC levels, check the filter life indicator and turn on the auto mode. According to the Blueair 200 series manual , the set LED intensity feature, changes the LED intensity of the visible lights on the unit. The night mode allows the activation and deactivation of certain settings at specific times.
The Blueair 280i sensor is exactly same sensor which is used in the ‘Blueair Aware’ air quality monitor. The sensor is different from the one used in the 270E model due to the fact it is designed to detect changes in temperature and humidity levels as well as PM2.5 and VOC’s.
Blueair have stated within the ‘Blueair Friend App’ that the sensor is able to measure over ‘900 different gases ’, including Formaldehyde and Toluene which is then summarised into a single figure displayed in the app.
The sensor also allows you to use the auto mode feature whereby the fan in the Blueair 280i air purifier automatically adjusts based on the level of contamination detected by the unit. For more information regarding the sensor, please check the ‘sensor’ description under the ‘features’ section
