HEPA standard

HEPA (High-Efficiency Particulate Air) is a standard for air filters that captures at least 99.97% of particles as small as 0.3 microns, including dust, pollen, mold spores, and some bacteria. This means it effectively reduces airborne contaminants, improving indoor air quality. HEPA filters are used in air purifiers, HVAC systems, and cleanrooms for environments requiring high cleanliness. The standard ensures filters meet strict performance criteria, making them reliable tools for controlling airborne pollutants in healthcare, manufacturing, and residential settings.
