Air purifier is one of the popular devices that is used for removing contaminates from the air. They are very useful for people suffering from asthma and allergies. They also play a very vital role in the elimination or reduction of tobacco smoke. These purifiers are also commercialized as small stand-alone units or larger units that can be added to an air handler unit (AHU) or to an HVAC unit that are available in various medical and commercial industries.

There are many people who are sensitive to pollen, dust, mold spores, pet dander and dust mites. They can pose a risk to the health of the individual. With the increase in technology, an air purifier has the ability to capture a large amount of virus, bacteria and DNA particles. These purifiers play a vital role to reduce the airborne contaminants and hence can be used by people suffering from asthma and allergies. There are plenty of ways with which these purifiers can be rated. Some of them are CADR; air charges per hour that reflects how frequently the purifier can exchange the air in the present room; efficient area coverage; the clean air delivery rate that determines the efficiency of purifying the air; cost of replacement of the filters and energy usage.

The working of the air purifier is very simple. The air passes through the air filters and gets filtered completely before it is being released in the room. Most of the very good purifiers have the ability to catch around 97 percent of the contaminants that float thereby reducing the risk of any health hazards. This is one of the important reasons why these purifiers are used these days.

There are different techniques that are by these air purifiers to purify air. The advantages vary with the kind of technique that is used. One of the very common techniques that are used is Ultraviolet germicidal irradiation. This helps in sterilizing the air that passes through the UV lamps via the forced air. These systems can be the ones that are freestanding units along with the shielded UV lamps and a fan that forces the air pass the UV light. Along with the forced air system, there are other systems that are installed to make the circulation of the micro-organisms away from the lamps. The major reason for sterilization to take place is the placement of UV lamps and the presence of a good filtration system that is used to remove the dead micro-organisms. However there are chances where the micro- organisms would not grow in the naturally damp places due to the presence of a UV lamp that is placed at the coils and the drain pan of cooling system. The best method that can be used for treating the air is the presence of the system that is placed in the centre of the duct and parallel to the flow of air rather than the presence of the coils in line with the duct systems.

Depending on the feature and the technique used, the cost of the purifier varies and with the amount of pollution now a days, an air purifier is extremely essential.
