Air Purifiers Processes

Today there are a number of different types of air purifiers a person can use both at home and in the work place.  In addition, there are even car air purifiers available today as well.  However, not only do these devices remove contaminants from the air they are both cost effective and good on the environment.  This is because they only require a small amount of electrical power to run them compared to other devices such as air conditioning and heating units.The different processes, which are often used inside air purifiers, are able to remove different types of contaminants from the air surrounding us and which we breathe.  Below we take a look at what these processes are. 1.  Filter Based - These trap airborne particles dependent upon their size.  The most effective types of filters to be found in these devices today are those known as HEPA Filters.  On average, one of these filters can remove 99.97% that are no bigger than 0.3 micrometers in size.
