If you experience water eyes, running nose, fever, flu like symptoms or incessant sneezes you may probably have be affected by some airborne allergens.  These may happen when you change environments, or they just come down through the atmosphere when there is a change of weather and temperature.  A good air purifier may be a safe and affordable way to prevent allergies; it has a series of filters that will help take the allergens out of the atmosphere we breathe.  You may wish to install these devices in places that you usually habit; your home, workplace and your car.


The way an air purifier works is by removing contaminants from the air; they are marketed to be beneficial to asthmatics, and sensitive people who are suffering from allergies, and also as a device used to minimize second hand smoke from tobacco. These purifiers are made to filter out pollen, dust, mold spores, and dust mite feces because these contain strong amounts allergens which may trigger an allergic reaction with some people.  Volatile Organic Compounds (VOC’s) and particles from smoke may also pose as a hazard in the air that we breathe.  Constant exposures to assorted components may increase the chances of acquiring sick building syndrome.


It is for this purpose that air purifiers are utilized to minimize the concentration of contaminants in the air.  There are several steps that a purifier needs to work effectively against the particular purpose that you want to address.


A filter works as a trap, which can block unwanted things to produce a refined state of something which you allow to let through.  Air filters have an initial stage that starts from a rough holed screen that gradually decreases in size to take away particles at a certain stage at a time.  A good High Efficiency Particulate Air (HEPA) filter is supposed to remove at least 99.97% of 0.3micrometer particles. Activated carbon comes next, which is made up of very porous materials and is also used to take away taste in water.  The carbon filter changes contaminants from a gaseous phase into a solid one.  An Ionizer is a component that can be added-on; its system uses a charged electrical surface to generate an electrically charged gas ion together with an air ion.  These ions then attach themselves to the airborne contaminants, and which in turn are then attracted to the charged collector plate.


So when shopping for an air purifier, try to look for a good one that offers a sufficient amount of filtration systems to suit your specific need.  There are a lot on the market to choose from that are safe and economical to use.
