What is a HEPA air purifier?
HEPA means high efficiency particulate arresting , a HEPA filter can remove almost 99.97 % of airborne particles of .3 micrometers or larger. These also include ordinary irritants and allergens like dust, pollen, mold and germs. The HEPA filter was invented in 1940 during the Manhattan Project by the US Atomic Commission to prevent the spread of airborne radioactive contaminants which were a result of atomic bomb test. HEPA filters were made commercially available in the 1950 and HEPA became the registered brand and a generic name for the most efficient filters. After years HEPA filters have been developed to please a greater demand for air purity not only in homes but also in many industries like aerospace, electronic micro circuitry, biopharmaceutical labs, and in office and commercial stores.
What are they good for?
HEPA air purifiers are very good for allergy relief. True HEPA filters, are perfect for removing all kind of contaminants that are greater than .3 microns in size. One micron is about one hundredth times smaller than the width of your hair. So, you can visualize just how tiny .3 micron is and the capability of this filter to be able to trap and remove such particles.
A good HEPA filters can provide a dry environment, ensuring the complete elimination of the germs as they cannot survive in dry conditions. Some HEPA filters are chemically treated to kill bacteria while others may have a germicidal ultra violet light to achieve the same result.
