  • High-efficiency particulate air filter (HEPA)

 Air filters must catch 99.97% of 0.3 micrometre particles to be considered a real HEPA filter, including viruses, bacteria, and smoke particles. HEPA filters are effective due to their high density, but they can harm fan motors in most household HVAC systems due to their slow airflow and potential damage to fan motors.
