HEPA filters work, not by forcing the air through small holes like a sieve, but by bending the air flow. The particles, which don’t change direction as well as the air, crash into the fibers and stick.
Extremely small particles (of molecular size) such as viruses are dominated by Brownian motion rather than gravity or inertia. This perpetual agitation causes them to impact the fibers and stick.
Tests conducted in the 1960’s found that HEPA filters could be 99.9999% efficient for bacteria and 99.999% efficient for viruses.
The fit of the filters in the filter chamber has a major influence on performance. Poor fit seriously degrades efficiency by allowing unfiltered air to
The AllerA ir 9600 Series has the unique Pressure Seal to avoid leaks and the HEPA
