What specific efficiency and particle size benchmark did the foundational HEPA filter technology establish?
Answer
99.97% of particles that are 0.3 micrometers in diameter
The High-Efficiency Particulate Air (HEPA) filter was designed to capture at least 99.97% of particles that are 0.3 micrometers in diameter, setting a very high standard for air cleaning.
