What is the respirator of HEPA?

The HEPA respirator is a respiratory helper that uses the filter of high -efficient air particles (HEPA). It is a cleaning air respirator, which means that the filter helps maintain harmful dust and other particles outside the air that the wearer breathes. Although the insulating mask or dust mask is made of thin material that covers the nose and mouth, the respirator HEPA is often much larger and stronger. HEPA respirators are usually made in three styles: those that cover only the mouth and nose, those that cover the whole face and those that cover the whole head. HEPA filters

were first developed at the age of 40 in the 20th century to prevent the spread of air radioactive materials during the Manhattan project. The Ministry of the United States and the European Union has set HEPA filters standards. The filters are usually made of glass fiber fibers that are randomly arranged to capture air particles. For example, according to US standards, the HEPA filter must eliminate at least 99.97 PERCorlum more .03 micrometers in diameter. In addition to their use in respirators, HEPA filters are also commonly used in air filtration and cleaning systems.

Someone who could be exposed to dangerous air particles, including bacteria, fungi, vapors, fog and gases, should be protected by a hep respirator. The respirators are commonly used by those working on welding, medicine, construction, demolition and various industrial shops. The HEPA respirator can also be used by the owner of a house that works to remove asbestos or lead, as well as landscape people and managers of pests who spray chemicals that could be harmful if inhaled.

HEPA respirators can be certified by certain organizations, such as the National Institute for Safety and Health at Work (NIOSH) in the United States. Filter evaluation system NIOSH KLAsifies the Best HEPA filter that can be used with any type of particle as a P100 filter. The HEPA R100 and N100 filters have a limitation of use. Before the HEPA respirators are used in the workplace, it is recommended that employers try to reduce the exposure of employees by other means by other means. If a respirator is still needed, employees should first be trained in how to use a respirator, and the respirator should be tested for correct adaptation.
