High-efficiency particulate air, i e , HEPA filter or HEPA vacuum that filters asbestos fibers
HEPA stands for High Efficiency Particle Arrestor, used to reduce the number of contaminants in indoor air A HEPA filter will arrest or stop 99 97% of all particles 3 microns or larger HEPA filters - used in "clean rooms" - are essential in medicine and in the manufacture of computer components However, they have limitations in vacuums They tend to leak in vacuums, because they were never intended to be used as small, portable filters They are expensive and must be discarded because they cannot be cleaned They clog quickly and strangle airflow And even when working perfectly, up to half the respirable particles in indoor air are small enough to go right through a HEPA filter Very, very few vacuums are truly "HEPA" certified but many only use filter material which is "HEPA" level Kiwivac offers bags for their systems that meet this filter material specifications
High Efficiency Particulate Air Filter has an efficiency of 99 97% HEPA - High Efficiency Particulate Air Filter has an efficiency of 99 97% efficiency for particles of 0 3 microns Biological Safety Cabinets filter air through one of more sets of HEPA filters
High efficiency particulate arrestance (filters) HUMIDIFIER FEVER: A respiratory illness caused by exposure to toxins from microorganisms found in wet or moist areas in humidifiers and air conditioners Also called air conditioner or ventilation fever HVAC: Heating, ventilation, and air-conditioning system HYPERSENSITIVITY DISEASES: Diseases characterized by allergic responses to pollutants The hypersensitivity diseases most clearly associated with indoor air quality are asthma, rhinitis, and hypersensitivity pneumonitis Hypersensitivity pneumonitis is a rare but serious disease that involves progressive lung damage as long as there is exposure to the causative agent HYPERSENSITIVITY PNEUMONITIS: A group of respiratory diseases that cause inflammation of the lung (specifically granulomatous cells) Most forms of hypersensitivity pneumonitis are caused by the inhalation of organic dusts, including molds
High-efficiency particulate air (HEPA) filter, which removes particles in the air by forcing it through screens containing microscopic pores
