Air purifiers are used in order to purify the air around us by removing dust, pollutants, allergens, contaminants, smoke, mites, bacteria, virus, pollen, molds, odors, gas, and so on. There is now a growing need of air purifiers as our environment now has an increasing air pollution.

It is good to be informed of the technology used in air purifying which basically categorized into two, and these are the active and passive.
Passive technology would involve the purification of air done by drawing it to the purifier. This means, the air being drawn would pass through the filters present in the purifier and thus purifying it from the contaminants. To name a few of passive technologies are the generic filters, activated carbon air filters, electrostatic precipitators, and UV filters.
Active technology on the other side is the system wherein the air is purified outside the unit that purifies, and this would give a kind of effect in the air. There are two kinds of active purifiers, and these are the ionizer purifiers and the ozone generators.
Another kind of air purifying technology is a combination of both active and passive, and the purifiers of this combined technologies are claimed to be more efficient than the purifiers of the individual technologies.

Allergies are one concern that most city dwellers would experience because of the dusty environment in the city. Most of the people are allergic to the dusty air in the city which consists of tiny dust particles like sand, tiny stones, pollen of plants and others.
Asthma is another concern, which is a chronic breathing disease, and of which will exaggerate once the person is breathing the air that is filled with impurities. Using air purifiers will not only filter the air from impurities but also be able to oxidize the surrounding air.
