Blueair Classic 405 Air Purifier

Recommended by Asthma Allergy Nordic, this quiet, compact air filtration unit is ideal for anyone looking to improve the air quality in mid-sized rooms of up to 40m².

The Nordic independent test institute, Testfakta, has rated it as the best performer compared to nine other brands, whilst MailOnline journalist, Alice Smellie, also ranked it more highly than the other competitor models that she tested.

Using Blueair HEPASilent Technology to remove virtually all airborne pollutants, the Classic 405 removes dust, pollen, viruses, bacteria and other irritants down to a particle size of 0.01 microns.

Testing by the accredited CAS Test Technical Services measured a 99.99% removal rate of the 12 most common viruses and bacteria by the Classic 280i, Classic 480i and Classic 680i, including swine flu (H1N1), E. coli, and Enterovirus (EV71).*

Wi-Fi enabled and compatible with the Blueair Friend app, the 405 has a user-friendly interface with LED-button control and icons, so that you can easily check operating speed and filter status.

And you don’t need to worry about it being too noisy as it only generates between 32 – 52 dB(A) depending on the setting.
