AIR PULLUTION
Indoor Air Quality (IAQ) deals with the content of interior air that could affect health and comfort of building occupants. The IAQ may be compromised by microbial contaminants (mold, bacteria), chemicals (such as carbon monoxide, radon), allergens, or any mass or energy stressor that can induce health effects. Recent findings have demonstrated that indoor air is often more polluted than outdoor air (albeit with different pollutants) although this has not changed the common understanding of air pollution. In fact, indoor air is often a greater health hazard than the corresponding outdoor setting. Using ventilation to dilute contaminants, filtration, and source control are the primary methods for improving indoor air quality in most buildings.
Techniques for analyzing IAQ include collection of air samples, collection of samples on building surfaces and computer modelling of air flow inside buildings. The resulting samples can be analyzed for mold, bacteria, chemicals or other stressors. These investigations can lead to an understanding of the sources of the contaminants and ultimately to strategies for removing the unwanted elements from the air.

ELECTRONIC AIR PURIFIERS
The technology used in air purifiers can be diverse and unique. There are many air purifier companies that use different types of technology and mediums to achieve the goal of clean air. Although there are different filtering systems used in air purifiers, many of the systems are just as efficient and effective. Each system has different qualities and specialties that make them exclusive and individualized. An “Electronic Air Purifier” is an air purifier that uses an advanced and effective type of technology to absorb contaminants in the air. Electronic air purifier systems are used for businesses and residences in order to keep the air indoor safer and healthier for people to breathe. The filtering system used in an electronic air purifier uses a cutting edge and knowledge of the behavior of contaminants in the air in order to work powerfully.

CREATOR
Frederick G. Cottrell developed the filters that are used in electronic air purifiers. Cottrell put forth the effort to invent the electronic filters due to all the smog and pollution he had to deal with in his environment. Cottrell lived in an environment with many smoke stacks that omitted the pollution and eventually he experimented with the capabilities of charged particles in order to clean the air.
Cottrell developed a process of charging particles of smog in the air. The charged particles were then attracted to an opposite charge, causing them to exit the air and stick to the medium. Cottrell found that the particles of dust and smog in the air were absorbed due tot his attraction and the air was cleaner. After Cottrell's process was developed, there were many other ways that the process was used including indoor electronic air purifiers.

TECHNOLOGY
Static electricity is the main source of technology used by electronic air purifiers in order to clean the air. The static that is developed by the machine is used to attach a charge to all particles in the air that is taken in by the air purifier. When the particles possess a charge, this charge is attracted to the opposite type of charge. This opposite charge is placed onto collection plates or other types of medium inside the air purifier. This medium attracts the charged particles and they stick to the charged medium instead of staying in the air. Electronic air purifiers are proven to be more efficient at absorbing particles. The reason electronic air purifiers are more effective at cleaning the air is that when particles are charged as opposed to just being absorbed, they stick easier to the medium. There are more particles removed and there is a better chance of them being absorbed by the filter when they possess the charge given by an electronic air purifier. An electronic air purifier is measured to have 95% efficiency or more. The size of collection plates, rate of air flowing through the air purifier and how much power is in the electric field are factors that can affect how much efficiency is mastered from the air purifier.

TYPES OF ELECTRONIC AIR PURIFIERS
There are two different types of electronic air purifiers. Some electronic air purifiers use a one-stage system to clean the air while some use a two-stage system. The one-stage system in an electronic air purifier charges the particles and sticks them to the collection plates. There is only one step that the air goes through of filtering once it enters the air purifier. In a two-stage system, however, the air enters the air purifier and the particles in the air are charged using high-voltage wires. The charged particles are then pulled into metal plates that are charged oppositely. Both types of electronic air purifiers are just as effective at removing particles from the air.
Both types of electronic air-purifying systems also require very low maintenance. There are no filters to change and the air purifiers tend to stay relatively clean. If there is build up that develops, the collection plates can be wiped down with a damp cloth. All of the build up from particles will be removed by a simple wipe and the collection plates will be good as new and perfectly charged. If the collection plates are kept clean and free from particle build up, they will remain efficient and effective in cleaning the air.

CONCLUTION AND RECOMMENDATION
Electronic air cleaners are able to remove particles, fumes, odors and gases from the air.
The technology used in electronic air cleaners makes them one of the most effective and advanced types of air purifiers on the market today.
Electronic air purifiers are an efficient and low maintenance type of air purifier.
They are easy to care for and deliver the same quality as other filtering systems on the market. With at least 95% efficiency, it's no wonder that electronic air purifiers are becoming a popular and convenient way to provide clean and healthy air.
