| | | Indoor Airborne Pollutant Types
According to the EPA, indoor air pollution is among the top five
environmental health risks affecting Americans today. The EPA recommends
addressing this risk by controlling or eliminating the sources of pollutants;
ventilating a home with more clean, outdoor air; and using an air purifier.
Indoor air pollutants usually fall into 2 distinct categories: particles and
gaseous pollutants.
Particulate matter usually includes dust, animal dander, dust mites,
mold, and pollen. HEPA
air purifiers are great for addressing these types of pollutants.
Gaseous pollutants, on the other hand, usually come from combustion sources
such as tobacco smoke, vehicle exhaust, paints, and cleaning products.
A carbon air purifier
is usually ideal for these pollutants. | | Top Air Purification Technologies Explained |
Confused about air cleaners or purifiers? Here's an explanation of the different types of air purifiers available: HEPA Filter Air Purifiers By definition, a HEPA filter air purifier is 99.97% effective at removing particles as small as 0.3 microns. This technology is ideal if you have problems with dust, pollen, or any other allergens. Ionic Air Purifiers An ionic air purifier or ionizer creates negative ions which change the polarity of airborne contaminants. These particles then fall from the air and away from the air your breathe. Ionizer air purifiers are silent and good at removing particles as well as neutralizing odors. UV Air Purifiers If you have a problem with mold or bacteria, look for a UV air purifier. This type of air purifier emits a UV light that kills microbiological contaminants such as mold, fungus, bacteria, and even viruses. Carbon Air Purifiers A carbon air purifier utilizes activated carbon, which behaves like a sponge and traps most airborne gases and chemicals. If you're concerned with tobacco smoke or odors, look for an air purifier with a carbon filter. |
| | Top 3 Air Purifier Buying Tips |
Air purifiers (also known as air cleaners) are designed to reduce airborne contaminants in your home and are great for allergy or asthma suffers. Here are some basic buying tips: Find the source of your contaminants. Indoor air pollution is quickly becoming a top environmental concern. If you're looking to purchase a home air purifier, one of the first things you should do is determine where the pollutants are coming from. Do you live with a smoker and need to get rid of tobacco smoke odors? Do you have pets and need to filter out pet dander? Is pollen making your allergies worse? Each one of these pollutants is best addressed by certain air purification methods, so find out where your contaminants are coming from. Determine what filtration methods you need. As a general rule, HEPA air purifiers are versatile and will work for most indoor pollution issues. HEPA filters boast 99.97% efficiency down to 0.3 microns or 1/100th of a human hair! Look for a HEPA air purifier if you have a problem with pollen, pet dander, or dust. To get rid of odors, gases, or smoke, look for an air purifier with activated carbon. For mold, mildew, or other biological contaminants, a UV air purifier would be your best bet. Learn what CADR means. CADR stands for Clean Air Delivery Rate. This is a certification program developed by the Association of Home Appliance Manufacturers (AHAM) to help consumers choose air purifiers. CADR is based on the cubic feet of air an air cleaner can filter per minute. The higher the CADR number, the faster and more efficient the air purifier will be at cleaning your air. |
