Biomedical applications of HEPA filters

In the biomedical field, HEPA filters are mainly used to filter organisms such as bacteria and viruses in the air, so as to prevent and control the transmission of related diseases caused by bacteria and viruses and other organisms.  In general, medical use of HEPA filtration systems are also combined with the use of high energy uv modules to kill viruses and live bacteria in the filter medium.  Some HEPA filters are rated with an HEPA unit efficiency rating of 99.995% for the control of diseases transmitted by airborne bacteria, viruses, or other harmful particulate matter.  

The vacuum cleaner  

Many vacuum cleaners also use HEPA filters as part of their filtration systems.  This is beneficial to asthma and allergy victims, as HEPA filters remove particles (such as pollen and dust mites) that trigger allergy and asthma symptoms.  HEPA filters are effective in vacuum cleaners, which must be designed so that all air is drawn into the machine and expelled through the filter.  And, because of the extra density of the HEPA filter, the vacuum cleaner requires a more powerful motor to provide full cleaning power.
