Electrostatic precipitation has been around since the early 1900s. It was first commercialized in 1907 by Dr. Frederick G. Cottrell. Since then, it has become a major player in the purification industry.
Why Is Electrostatic Precipitation The Best?
Escaping Particulates
With electrostatic precipitation, extremely small particulates (.01 - 1 micron) can be filtered out. The smallest particulates a Hepa filter can filter out is .3 microns. This means that for every 10,000 particles which pass through a filter, the electrostatic filter lets 1 (or less) escape and the Hepa filter may let 3 escape. We compare electrostatic filtration with Hepa filtration because Hepa filters are considered to be the second best form of filtration. Hepa filtration is used primarily to remove dust, pollen, mold spores. In addition, electrostatic filtration goes a step further by removing bacteria, viruses, cigarette smoke, and chemical fumes.
Cost
Electrostatic precipitation is less expensive, in the long run. It is more expensive in the original purchase. However, you will save, in the long run, because you don't have to buy replacement filters. Replacement filters can be quite expensive and inconvenient to replace. Keep in mind, that the ion charged plates need to be cleaned regularly for maximum performance.
The fan does not need to be as powerful. Hepa filters push air through a fine filter. The design requires a heavy duty fan to push the air. Electrostatic models have virtually no wind resistance and don't require the pushing power of other models.
Recommendations:
Hepa and electrostatic filtration are both effective. Hepa has one distinct advantage in that it doesn't produce ozone. Too much ozone is not good to breath and some electrostatic models have been know to produce excess ozone. All things considered, a hybrid electrostatic (Hepa and electrostatic combined) is our preferred filtration method.
Finally, any form of air filtration should have a good fan. Air must be circulated throughout the entire home. Don't consider an electrostatic purifier that is silent (no fan). In addition, if you purchase a purifier with Hepa filtration make sure there is a pre filter. Pre filters are much less costly to replace.
