Do Allergy Air Purifiers Really Work?

If there are times that you have that feeling of watery eyes or have continuous sneezes when you transfer to certain places or there is a change in environment, or perhaps have fits at particular times of the year, then there may be a strong possibility that you are affected by some airborne allergens.  These come down through the atmosphere when there is a change in temperature and wind direction. Among several available and affordable ways to treat allergies, some people invest in air purifiers. They believe it can help filter out allergens that enter their home and make the atmosphere inside cleaner.


An air purifier initially works by removing contaminants from the air; they are particularly marketed to be beneficial to asthmatics, those suffering from allergies and as a device used to reduce second hand some from tobacco. These kinds of purifiers are designed to filter out dust, mold spores, pollen and dust mite feces because these acts as allergens which trigger an allergic reaction with people.  Volatile Organic Compounds (VOC’s) and particles from smoke may also cause a hazard in the air that we breathe.  Constant exposures to these components will increase the chances of acquiring sick building syndrome.


Air Purifiers are utilized to minimize the concentration of these contaminants in the air.  There are several stages that a purifier needs to effectively work against the particular purpose that you want it to function for.


A filter is by essence a trap, which upon its design can block unwanted things to produce a refined state of something which you allow to let through.  These filters first work by starting from a rough holed screen and gradually decreasing the sizes of the holes to take away larger particles.  A High Efficiency Particulate Air (HEPA) filter is supposed to remove 99.97% of 0.3micrometer particles. This serves as your first stage of defense.  Activated carbon, which is a very porous material and is also used to take away taste in water, is then employed.  It forms a process of changing the contaminants from a gaseous phase into a solid one.  An Ionizer uses charged electrical surfaces to generate electrically charged air or gas ions.  These ions attach themselves to the airborne contaminants and are then attracted to the charged collector plate.


So try to choose an air purifier which can have sufficient amount for filtration systems to your specific need.  There are a lot on the market to choose from and are safe and economical to use.
