Air purifiers are devices that clean the air of all contaminants such as bacteria, viruses, pet allergens or dust particles. Air purifiers are really beneficial for people who suffer from certain allergies and asthma. This device also reduces, or in small confined spaces, completely eliminates the risk of second-hand smoking.
Most commercial types of air purifiers are small stand-alone device for small offices or for use in your house built. There are also larger air purifier that an AHU (air handling unit) or an HVAC (Heating ventilation and air conditioning) systems that are used for commercial, industrial or medical applications can be secured, especially in larger rooms.
There are various ways in which air purifier to clean the air. Each process has various effectiveness that removes different kinds of impurities. The good thing about air purifiers is that you have different processes in one machine so that you gain all the advantages in different processes.
The easiest way is by filtering. With the use of fans, air is forced through a filter, there are traps impurities. The disadvantage of this method is that the smaller particles pass through the filter. It is a pre-filter and the high-efficiency particulate air or HEPA filter. HEPA filter to remove 99.97% of particles larger than 0.3 microns.
Air purification systems using ultraviolet germicidal irradiation ultraviolet light, in order to clean the air cleaning by the bacteria passes through the UV-light. This is achieved by forcing contaminated air to a UV lamp happened to happen with the use of fans, the dead bacteria, dead bacteria is a clean filtered out leave safely breathe free air for you.
There are also air purifiers, activated carbon, using volatile chemicals absorbed. The absorption is at a molecular level. But this process does not remove larger particles. The main use of activated carbon is that it modifies contaminants from the gaseous state in the solid state. This method is typically used with a different cleaning process.
Ionic air purifiers use charged electrical materials, which are formed in flat surfaces or needles to create these electrically charged gas ions. These ions are to attach impurities suspended solid particles in general. These are collected by the use in a charged electrostatic plate. Although this method is very effective, it generates ozone and other oxidants, as byproducts. Thus, ionic air purifier should only produce as much as 0.05 ppm (particles per micrometer) of ozone insist on the industrial safety standards.
In conclusion, these are just a few of the many methods of air purification and as the technology advances several types of air purification are discovered. If you are suffering from asthma or allergies, such suffering allergic to cigarette smoke or tree pollen, can help to buy an air purifier to reduce your allergic reactions and make life easier....
