HEPA stands for High-Efficiency Particulate Arrestance (HEPA), and is a type of air filter. Filters meeting the HEPA standard have many applications in medical facilities, clean rooms, automobiles, aircraft and homes. HEPA filters must satisfy certain standards of efficiency such as those set by the United States Department of Energy (DOE). To qualify as HEPA by US government standards, an air filter must remove (from the air that passes through) 99.97% of particles that have a size of 0.3 µm. HEPA filter's minimal resistance to airflow, or pressure drop, is generally specified as 300 pascals (0.044 psi) at its nominal flow rate. HEPA filtration works by mechanical means and does not resemble the Ionic and Ozone filtration methods which use negative ions and ozone gas respectively. Therefore, the chances of potential pulmonary side-effects like asthma and allergies is a much lower with HEPA filtering systems. HEPA filters are also used in quality vacuum cleaners effectively to protect asthma and allergy sufferers, because HEPA filter traps fine particles such as pollens and dust mite feces which trigger allergy and asthma symptoms.
