A HEPA (High Efficiency Particulate Air) filter is a type of air filter that is designed to remove tiny particles from the air. HEPA filters are used in a variety of settings where air quality is important, including homes, hospitals, laboratories, and industrial facilities.
HEPA filters are particularly effective at capturing particles that are 0.3 microns in size or larger, including dust, pollen, pet dander, mold spores, and some bacteria and viruses. This is because HEPA filters use a dense network of fibers to trap particles as air passes through them.
In homes, HEPA filters are often used in air purifiers or as part of HVAC systems to improve indoor air quality. In medical settings, HEPA filters are used to prevent the spread of airborne diseases, and in industrial settings, they are used to prevent the release of harmful particles into the air.
It’s important to note that while HEPA filters are highly effective at removing particles from the air, they do not remove gases or odors. To remove these types of contaminants, additional filters or air purifiers may be needed.
