3. HEPA - Wikipedia

   en.wikipedia.org/wiki/HEPA

   HEPA (/ ˈ h ɛ p ə /, high efficiency particulate air) filter, [1] also known as a high efficiency particulate arresting filter, [2] is an efficiency standard of air filters. [ 3 ] Filters meeting the HEPA standard must satisfy certain levels of efficiency.

4. Dust collector - Wikipedia

   en.wikipedia.org/wiki/Dust_collector

   However, they are seldom used as primary dust collectors because of their large space requirements and low efficiency. A practical use is as precleaners for more efficient collect. Advantages: 1) simple construction and low cost 2) maintenance free 3) collects particles without need of water. Disadvantages: 1) low efficiency 2) large space ...

5. Air filter - Wikipedia

   en.wikipedia.org/wiki/Air_filter

   The filter must satisfy certain standards of efficiency such as those set by the United States Department of Energy (DOE). Varying standards define what qualifies as a HEPA filter. The two most common standards require that an air filter must remove (from the air that passes through) 99.95% (European Standard) [ 4 ] or 99.97% (ASME standard ...

6. Air purifier - Wikipedia

   en.wikipedia.org/wiki/Air_purifier

   A high-efficiency MERV 14 filter has a capture rate of at least 75% for particles between 0.3 and 1.0 micrometers. Although the capture rate of a MERV filter is lower than that of a HEPA filter, a central air system can move significantly more air in the same period of time.

7. Electrostatic precipitator - Wikipedia

   en.wikipedia.org/wiki/Electrostatic_precipitator

   The first use of corona discharge to remove particles from an aerosol was by Hohlfeld in 1824. [2] However, it was not commercialized until almost a century later. In 1907 Frederick Gardner Cottrell, a professor of chemistry at the University of California, Berkeley, applied for a patent on a device for charging particles and then collecting them through electrostatic attraction—the first ...
