Ionic Air Purifiers

Particles in the air carry a positive charge. An ionic air purifier fitted near the ceiling of a room emits a steady stream of negatively charged ions. This attracts the positively charged particles of dust and allergens and they form clumps with the negative ion stream and fall to the ground because of their combined weight. The ambient air becomes free of the germ carrying particles and the clumps on the floor can be swept away and cleaned in conventional manner. This kind of purifier also serves to refresh a room by removing stale air that tends to be malodorous. The capacity of an ionic air purifier is measured in the number of air changes per hour that is the time taken for a unit to provide clean air in a given space. It may be necessary to have more than one ionic air purifier in series in a large room or one frequented by relatively high traffic.

Some ionic air purifiers also generate ozone by high voltage current. Ozone kills bacteria that may otherwise be inhaled. However ozone is hazardous in excess of requirements and its generation needs to be controlled within limits. Ionic air purifiers are economical to operate and effective in improving inhaled air quality. Ionic air purifiers are generally designed to draw current from a mains source of electric power. It suffices to clean the ionic air purifier weekly and the unit occupies less wall space than an air conditioner. The model design should aid easy filter removal and cleaning.

Ionic air purifiers are most useful in areas where infection potential needs to be kept down. Areas for surgery in medical establishments and manufacturing areas for pharmaceuticals and electronic components are common examples. Public restrooms and public transport vehicles or anyplace where many people transit through a relatively small-enclosed space, are also examples of places where deployment of ionic air purifiers can be useful. Small units can be used in cars and in private rooms as well.

Some ionic air purifiers have fans to help circulate the negatively charged ions and to attract positively charged particles as well. These models may be too noisy to use in areas where people need to sleep undisturbed. An ionic air purifier can provide clean air to breathe, even without a fan, if allowed to operate for some time in an area that is restricted for public movement.Ionic air purifiers play a significant role in public health by providing clean air to breathe and by controlling the spread and incidence of air-borne pathogens, microbes, dust and allergens.
