Welcome to Blueair Classic 405 Air Purifier. 

With a contemporary and discreet design, the Classic 405 air purifier can be placed anywhere in your home to provide a quiet yet powerful and energy efficient air filtration for air quality that is clean.


The Blueair Classic 405 uses Blueair's patented HEPASilent Technology to remove virtually all airborne pollutants in medium size rooms. Using electrostatic and mechanical filtration, the HEPASilent Technology is a revolutionary combination of advanced filter media and an encapsulated particle-charging chamber. This ensures that your Blueair purifier delivers results far superior than either mechanical or electrostatic technology alone. The HEPASilent filtration technology purifies the air around us to at least 99.97% of all airborne particles down to a size of 0.1 microns. Meaning viruses and bacteria are removed more than they would be from normal HEPA filters.

This is the only true way to compare like for like between air purifiers when assessing how powerful they are. CADR is not the same as air volume which will always appear higher due to the fact that it is only a measurement of the units fan power (with no filter Installed).
