Ionic Air Purifiers / Ion Generators

What is an ionic air purifier?

Negative ion purifiers generate negative ions and distribute them into the room's air. The ions create a static charge which causes particles in the air to be attracted to the room's surfaces - walls, drapes, floors, table tops, curtains, occupants, etc. This process temporarily removes particles from the air, but does not remove them from the room. Often, they can be stirred up again when a gentle breeze from someone walking by etc.

What contaminants do ionic air purifiers remove?

Ionic air purifiers offer fair reduction of general dust, particulate, and common allergens; however, charged particles may cling to objects in the home and soil them. Since HEPA filtration offers better performance without the problems associated with ion generation, we do not recommend the use of ionic air purifiers in home or clinical air purifiers.

Evaluation of Ionic Air Purifier Technology

We have a number of very serious concerns regarding the safety and effectiveness of most ionic air purifiers. Accordingly, we do not recommend their use for any air purification task. In our opinion, there are more effective and much safer technologies available for a comparable price.

Most notably, ionic air purifiers generate significant levels of ozone which is widely recognized as a considerable health threat due to its ability to damage healthy lung tissue and otherwise irritate respiratory passages.

What to Look for in an Ionic Air Purifier

We do not recommend ionic air purifiers. A HEPA filter is a more effective choice for residential and clinical air purification.
