What does HEPA stand for?
HEPA stands for High Efficiency Particulate Air. Blueair’s patented HEPASilent™ filtration technology effectively removes 99.97% of all airborne particles that are 0.1 micron or larger from the air that passes through the filter.
Pushing the air through the filter typically requires a strong fan motor, which can be noisy. To make Blueair unit’s whisper-silent, the company uses sturdy steel housing combined with soundproofing material.
