    Blueair Classic 405 HEPASilent Air Purifier

    Designed for mid-sized rooms, the next generation Blueair Classic 405 HEPASilent™ Air Purifier gets the job done – quietly and effectively. The Blueair HEPASilent air purifier Classic 405 provides clean healthy air that is virtually free of asthma and allergy triggers and indoor air pollutants. Wi-Fi enabled, the Classic 405 can be controlled with your smart device with just the touch of your fingertips.

    The Classic 405 features Blueair's HEPASilent™ air purifier Technology that uses both electrostatic and mechanical filtration, a revolutionary combination of advanced filter media and an encapsulated particle-charging chamber. Blueair Classic air purifier delivers results far superior than and other air purifier that offers either mechanical or electrostatic technology alone. Advanced filtration, HEPASilent™ Technology removes  99.97% of airborne particles down to 0.1 micron such as dust pollen, bacteria, virus, pet dander, mold spores and other airborne particles with additional sheets of activated carbon to remove gaseous pollutants.

    While the HEPASilent Particle Filter captures some light odors and gases, Blueair's optional SmokeStop™ filter (which also includes HEPASilent™ particle filtration) removes 98% of gases, odors and VOCs, and is recommended where removal of gaseous pollutants is a concern.

    Easy-to-control and Wi-Fi enabled! The new Blueair Classic 405 offers a touch button control panel with easy-to-read LED icons let you see the status of your air purifier's operating speed, Wi-Fi connection and filter. Download the free Blueair Friend app and you will be able to control the power and speed of the new Blueair Classic from a smart device from home or afar and have access outdoor air quality data in real time.
