A HEPA (High Efficiency Particulate Air) filter is a type of air filter that is designed to capture extremely small particles from the air, including dust, pollen, smoke, and other airborne allergens. In the context of an air purifier, a HEPA filter is a crucial component that helps to remove impurities from the air, improving indoor air quality and promoting better health.
In a HEPA air purifier, the filter is typically made up of a mat of randomly arranged fibers, which are designed to capture particles as small as 0.3 microns. This means that the filter can trap 99.97% of particles that are 0.3 microns or larger, including:
- Dust and dust mites
- Pollen and pet dander
- Smoke and soot
- Bacteria and viruses
- Mold and fungi
