At typical Blueair classic fashion, Blueair 405 is built with fully recyclable galvanized steel that will not release toxin chemicals like plastic based counterpart. The 20 x 23 x 11 in (50.8 x 58.4 x 27.9 cm) dimension is between 205 and 605. Hardly consider compact, Blueair 405 is still suitable for bedroom or tight corner although you should never place it under a shelf due to its 33 lb (15 kg) weight. Mobility wise is not great despite the lighter weight and side handles as Blueair 405 does not comes with casters by default like 605.
Continue with controls and usability, Blueair 405 can be controlled remotely via smartphone (more on this later) and there is physical control panel at the usual top spot with the same button layout. Each button is clearly labelled with live LED icon update. E.g. the fan speed LED icon will light up grey when there is no power source, outer circle blue with all bars are grey with power source (plugged in), 1 blue bar at first speed, 2 blue bars at second speed and 3 blue bars at third speed. As for middle Wi-Fi button, the LED icon will remain grey if there is no Wi-Fi, blinking when there is Wi-Fi connection and is ready to connect and stay with blue when it is Wi-Fi connected. Finally for the filter button, LED icon will light up in grey + blue when no replacement filter is needed and change to orange when filter change is needed. Simply hold the button for 5 seconds to reset the LED status.
Finishing up Blueair 405 specification, you have the standard 3-stage HEPASilent Technology, 3 speed, smartphone access, easy filter replacement with no screws needed, filter replacement indicator, zero ozone emission, CARB certified, ENERGY STAR rated and 5 years warranty.
