Electrostatic Air Purifiers
These air cleaners contain negative ion generators that charge the airborne particles. Then, the particles are attracted to charged metal plates or household surfaces. According to American Asthma and Allergic Foundation of America (AAFA), to operate effectively, these types of air cleaners need regular maintainance. In addition, these are seen to operate less effectively even at the beginning. Available Electronic Air Purifiers There are electrostatic purifiers available from several manufacturers, including Friedrich. The Friedrich electrostatic cleaner works in four stages: An air cleaner pre-filter catches larger particles as room air is drawn through a rear grill In the electronic cell microscopic particles become electrically charged as they pass through a electric field Then, collector plates attract these charged particles Lastly, an activated carbon filter removes common odors and fumes and the conditioned air is circulated back into the room Other manufacturers include Electrolux and Ionic Breeze. |
