Air purifiers use one or more methods of filtration and air treatment to remove pollutants from the air. Air purifiers using HEPA filtration can filter air particles up to 0.3 microns in size with an efficiency rating of 99.97%. As a result, air purifiers help businesses, construction sites or other project areas maintain a "safe breathing" zone. They work together with a negative pressure machine that helps keep particles in the air within a certain zone.
HEPA technology was created by the US Army Chemical Corps to remove bacteria, dust, chemicals, allergens and radioactive toxins from the air. Air purifiers that use this technology are powerful air purifiers.
