The Blueair 405 is part of the newest range of air purifiers from Blueair released in January 2017 and is the follow up model of the 450E. The Blueair 405 has an improved airflow rate of up to 20% on the highest speed setting compared to the 450E. On the highest speed setting, the Blueair 405 has an airflow rate of 595 m3/h which is more than the 475 m3/h of the 450E. The size, weight, overall look and the filtration technology used however, is exactly the same. One of the new features of the Blueair 405 is its Wi-Fi connectablility, allowing you to connect to the air purifier via your phone and Wi-Fi network and make adjustments to how it operates. With the Blueair 405, you get a new ‘hidden’ display with touch buttons which is located under a flip-up lid on top of the unit. The Blueair 405 would be a good choice for medium sized environments and can be used at night time with its low fan settings.
The Blueair 405 is able to be paired with the ‘Blueair Aware’ air quality monitor and then set to auto mode so that the fans can adjust based on the levels of contamination detected by the sensor in the Blueair Aware.
