Are HEPA filter viruses true?
Air purifiers with HEPA filtration efficiently capture particles the size of (and far smaller than) the virus that causes COVID-19, so the answer is yes. … It falls squarely within the particle-size range that HEPA filters capture with extraordinary efficiency: 0.01 micron (10 nanometers) and above.

What are HEPA filters made out of?
The difference between a HEPA filter and other filters is that HEPA filters are made of thin fibers of glass, and contain some level of activated carbon-based material.
What is a true HEPA filter?
