A: Yes — you can use a Blueair Blue Pure Max air purifier alongside a humidifier. In fact, combining the two can be a smart way to improve indoor air quality and comfort: The air purifier filters out airborne particles (like dust, pet dander, pollen, etc.), while the humidifier adds moisture to the air — so they work toward different, but complementary, goals. It’s best to place them a few feet apart so airflow isn’t restricted and both devices can operate efficiently.

A: Thank you for your question! Blueair products connect using a 2.4 GHz Wi-Fi network, which is the same frequency most smart devices use. If you don’t see the option to select 2.4 GHz on your phone, your router may be combining the 2.4 GHz and 5 GHz bands under one network name. You can usually adjust this in your router settings to enable or separate the 2.4 GHz connection.
