With electrostatic air purifiers, 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 purification with Hepa filtration because Hepa filters are considered to be the second best form of filtration.
