3 Benefits of ESP Electrostatic Precipitator Air Purifier
ESP is an air filtering device that uses electrostatic charge to remove dust particles. ESP ionizes the air by applying high voltage to the electrodes. Dust particles are charged by the ionized air and collected on the oppositely charged collecting plates. Since ESP actively removes dust and smoke from the gas, the system works well for wide range of biomass including wood, feces and low-quality coal which produce a lot of smoke. Moreover, ESPs boast collection efficiency (the ratio of particle counts entering and leaving the filter) that is usually higher than 99 %. [1] Provided that the right design approach is taken, it is possible to implement a versatile low- power ESP air cleaner.
3 Benefits of ESP Electrostatic Precipitator Air Purifier
Low cost: There is an initial one-time cost for an electrostatic air filter unit either portable air purifier or installed in your HVAC system.
Washable/Reusable: Collector plates within the device can be washed off and reused.
Effective: Electrostatic filters with collector plates do a fairly good job of removing dust and other particles from the air, as long as the plates are kept clean.
The EPA(United States Environmental Protection Agency) uses four standards of measure to determine how well an air cleaner can remove particles from the air. The one that applies here is called the atmospheric dust spot efficiency test, which measures how well the filter can remove fine airborne dust particles from building up on surfaces. The agency reports that electrostatic precipitators have an efficiency of up to 98 percent according to this test (if the air passes through the device slowly), mainly because they can remove fine particles.
However, this high initial efficiency depends on if the filter is clean. Efficiency will reduce as particles get loaded on the collector plates, or the airflow velocity increases or becomes less uniform. It is good to keep in mind that these tests are conducted in controlled laboratory settings that may not reflect real-life conditions.
