How does the ionizer air purifiers work? They have sets of plates that are electrically charged; here is where the air will pass. The electrically neutral molecules will be bombarded by the negative ions, consequently knocking off the electrons found in the neutral molecules or simply attaching to the electrons.

Once the electrons are knocked out, the air molecules turns to having positive charge because of lack of negative electrons, or if they attached to the electrons, become charged negatively. In the end, we have to two ion types that flow freely in the air with same charged dust, animal dander and other particles.

Ionic air purifiers are best suited for such type of problem – by providing great relief from asthma problems by way of clean air circulation. Air purifier ionizers are all quality tested for above par performance; this ensures that allergens are completely removed and taken away from the area where it is made to work.

Additionally, aside from the electric precipitation function they provide to relieve allergic reaction, ionizer air purifiers use HEPA or High Efficiency Particulate Air filter, which works well in removing offensive odor.
