26. Why do HEPA filters have a 0.3 micron pore size?
How to Answer
HEPA (High-Efficiency Particle Air) filters are an essential part of the pharmaceutical and healthcare industries, where sterile environments are mandatory. Share your understanding of their importance.
1st Answer Example
"The smaller the micron, the harder it is to filter out of the air. Bacteria can be as small as 0.3 microns, which is why 0.3 micron HEPA filters are used in pharmaceutical companies."
2nd Answer Example
"A standard air filter usually eliminates medium to larger particles from the air. However, they don't have the capabilities to almost completely eradicate tiny micron size particles from the air as a HEPA filter does."
