Do HEPA Filters Really Catch Coronavirus Particles ...

2021-11-11  Q. What’s a HEPA filter and can it catch particles as small as a coronavirus? A: HEPA is the international gold standard for filtering particles—it means that 99.97 percent of particles 0.3 microns in diameter are trapped. For context, a human hair is 50 microns across. The HEPA standard is more than 100 times smaller because it’s more difficult to trap particles that are smaller or ...
