Compared Against HEPA Air Purifiers

The comparison between HEPA air purifiers and ionic air purifiers is not as simple as you might think. Ionic air purifiers do roughly the same job as a true HEPA air purifier, just not quite as efficiently. They make up for this by silently running 24 hours a day while using very little power. In addition, there are no filters to change, only a bar to wipe off every week or so. HEPA air purifiers are limited by their filter element. They stop what cannot physically pass through that filter. With a true HEPA air purifier, that's 99.7% of the most dangerous particles. With a HEPA-type air purifier, there's no standard at all. Ionic air purifiers all work the same, and are limited only by how much air they can move. Since they electronically attract particles, they will eventually clean the air of just about everything, while a HEPA-type air purifier will never catch whatever passes through the holes. Keep that in mind when comparing. The ionic air purifier is limited to particles that are 1 micron or bigger, though. True HEPA air purifiers stop particles that are 0.3 microns in size, which are proven to be some of the worst on the human respiratory system.
