What does HEPA stand for?

HEPA stands for High-Efficiency Particulate Air. This term specifically refers to a type of air filter that is highly effective at trapping a large number of very small particles, including dust, pollen, and other allergens. The efficiency of HEPA filters is defined by their ability to capture 99.97% of particles that are 0.3 microns or larger in size.

These filters are widely used in settings that require stringent air quality control, such as hospitals, laboratories, and in various types of industry as well as in residential environments for improving indoor air quality. Understanding the importance and function of HEPA filters is crucial for anyone involved in industries related to air quality, lead abatement, or environmental health, as these filters play a significant role in minimizing exposure to harmful airborne contaminants.
