High Efficiency Particulate Air filters capture small particles and allergens from the air. These can be helpful for those who have allergies and are sensitive to airborne allergens. Removing and reducing the amount of allergy causing particles from the air you breathe can help to reduce allergy symptoms for some people. True HEPA filters must pass a quality standard test stating that they collect at least 99.97 percent of the airborne particles and substances filtered. Having this quality distinction is what separates true HEPA filters from HEPA-type filters.
True or absolute HEPA filters originated in the 1940's and was created by governmental agencies to stop the spread of certain contaminants. Since then, companies have created various consumer oriented products targetting air filtration with an emphasis on removing air borne contaminants such as mold spores, dust particles and other allergy related substances and allergens. Environments that demand high efficiency clean air standards such as health and medical clean rooms, and laboratories will use the true HEPA filter. The products that make claims of being HEPA-type, have not passed the same quality standards and tests that the true or absolute filters have passed, and are not considered as efficient.
