What type of Wi-Fi network does the Blueair app support?

Our Blueair air purifiers only support 2.4Ghz signals.

Please note that if the Wi-Fi router and air purifier are placed too far apart or are separated by thick walls, signal strength may be low. To avoid low signal strength, please make sure your air purifier and smart device are close to your Wi-Fi router during the initial pairing setup.
