Guide To Allergy Relief Air Purifierby Masni Rizal Mansor The deteriorating quality of indoor air is now a matter of growing health concern. Pollutant levels are 2 to 5 times higher inside the home than out, according to the EPA. Apart from gases and chemicals, these pollutants include airborne particles and particulate matter, which can be allergens causing different types of allergies. An allergy relief air purifier can improve indoor air quality, thereby reducing the chances of people having allergies. Apart from controlling the source and improving ventilation, an allergy relief air purifier is the best way to tackle this problem. A good allergy relief air purifier is capable of greatly improving the quality of indoor air. But you must carefully choose from the numerous types and brands of purifiers that are now available in the market. It is because some of the air purifiers can cause some of the very problems they are meant to get rid of. An allergy relief air purifier may be of various types. HEPA (High Efficiency Particulate Air) Purifier is one of them. These air purifiers filter a minimum of 99.97% of particles 0.3 microns and larger, which include allergens and contaminants like dust mites, dust mite feces, mold spores, pollen and animal dander. They offer cleaner air to help you breathe better. The U.S. Department of Homeland Security recommends HEPA air purifiers, and it's the highest current standard in air filtration. When you purchase a HEPA purifier, you should take into account the size and quality of the filter medium. Activated carbon filter is another type of purifier that helps removal of gases, odors and toxins. In such purifiers, chemicals, gases, and odors stick to the carbon and are "adsorbed" onto its huge surface area, bonding to the surface through chemical attraction. An electrostatic precipitator can also be called an allergy relief air purifier which ionizes particles as they are passed over an electronic cell, after which they are attracted and trapped by oppositely charged collector plates. Although you don't need to replace filters with this product, you have to wash the collector plate regularly to keep the purifier effective. Many ionization air cleaners generate ozone, which is a documented health hazard and lung irritant. The EPA has strongly discouraged the use of ozone generators as air purifiers. As different homes have different air contaminant sources to deal with, including both airborne particulates and allergens, and household chemicals and odors, it is always better to find an air purifier which combines a HEPA filter with some amount of carbon. This combination, apart from acting as an allergy relief air purifier, will remove the widest variety of indoor pollutants. |
