Since there are different types of air purifiers for different type of allergy or asthma situation, therefore it is difficult to select the best one. Moreover there are different types of allergens and home pollutions that can be removed only by different ways. The air purifiers of High Energy Particle Arresting were made to deal with the particles of dust and other airborne pollution in commercial clean rooms. These air purifiers were developed for the atomic energy commission and are made up of paper or polymer sheet that restricts flow of dust and other airborne pollution, refining the air with the tiny holes that allow fresh air to pass though the material. To pass a reasonable amount of airflow through the material you need a lot of surface area. Therefore the medium is folded in zigzag way to get a big surface area in a small area. In one of the other technology, the holes in the HEPA filter are larger so that the airflow is easy but it incorporates electrostatic wands to attract any left dust or pollutant particles from the air. The filters of the HEPA air purifiers should be changed periodically for good health and proper functioning of the device. You should consider the cost of the air purifier and its replacement filters before purchasing the purifier. Also review the details such as how much air passes the filter, expiry date of the filter, fan noise etc of the air purifier. You can also opt for UV air purifiers that use ultraviolet light to purify the air. The bacteria and viruses are destroyed by the right intensity of ultraviolet light. The main drawback of the UV air purifiers is that it cannot remove air particles or gas pollutants and hence has to be used with other purifiers that have filter system. A stream of negatively charged Ions is used in the Ion Generator Air Purifiers. Main benefit is that these air purifiers are small in size. When the particle bumps up against something it sticks due to the electronic charge on it due to the ions charge. This type of air purifiers are used in the poultry industry to overcome the problem due to feather dust and in US submarines. The main disadvantage of using these air purifiers is that the walls of the device turn black when the particulates stick to your device. These air purifiers do not have fan, hence they can function only in a localized area. Moreover these purifiers cannot stop gas pollution. Dont be impressed by any promotional hype and select the type of air purifier you need and desire according to your requirements. Be cautious while choosing the air purifier as your health depends on it. About the Author: Greg Culver is the owner of www.theshoppinggalaxy.com.
