What do High-efficiency particulate air (HEPA) filters do?

A) Break down a chemical in the presence of water.
B) Filters that remove 99.97% of particles larger than 0.3 micrometers.
C) A pesticide used for pest resistance.
D) Overheat the body when used incorrectly.

The correct answer is: B) Filters that remove 99.97% of particles larger than 0.3 micrometers.

High-efficiency particulate air (HEPA) filters are designed to remove 99.97% of particles larger than 0.3 micrometers. These filters are commonly used in environments where clean air quality is critical, such as in pesticide application to minimize the exposure of applicators and other individuals to potentially harmful pesticide particles. HEPA filters are efficient in trapping small particles, thereby helping to maintain a healthier and safer working environment.
