Do smoky cigars, lingering pet odors, or strong fumes pollute the air in your home? Although odors and foul smells are a part of life, they dont need to be a part of your indoor air. A HEPA air purifier can improve your indoor air quality dramatically.
Anyone with small children, pets, or a smoker in the house knows all too well that room deodorizers and air fresheners only mask the smell temporarily and dont solve your real air cleaning needs. To gain fresh, clean air, the odors in your home must be neutralized and cleaned completely. Odors like strong cooking smells, chemical fumes, and tobacco smoke are particularly dangerous for people suffering from asthma and allergies. As the air reaches the lungs, these bothersome odors and fumes trigger allergic and asthmatic reactions.
When deciding which air purifier will be most effective against household gases, odors and fumes, first consider the amount of air each air purifier can effectively process. The CADR, or Clean Air Delivery Rate, is used to measure the overall effectiveness of an air purifier and is tested and certified by the Association of Home Appliance Manufacturers (AHAM).
As air cycles through the air cleaner, the CADR measures the volume of air actually moving through the system, and the percentage and size of the particles being removed. CADR tests for pollutants like tobacco smoke, dust and pollen. These tests determine, in cubic feet per minute (CFM), how effective the air cleaner is at removing specific pollutants.
CADR results are recognized as accurate and impartial measurements by the U.S. Environmental Protection Agency (EPA) and the American Lung Association. Although some manufacturers use the air exchange rate to qualify their air cleaners, it is not comparable to the CADR tests. Air exchange rates only indicate the total volume of air that is processed by the air purifier in a given time and does not account for the particles being filtered or the overall effectiveness of the air purifier. Keep in mind that CADR is only one item to consider. Many manufacturers are not a part of the AHAM trade association nor do they submit their products for testing. CADR results have often skewed in favor of ozone generators and ionizers and thus should be taken for what they are - one of few impartial measurements of air purifier effectiveness.
Air cleaners utilize various methods of filtration for neutralizing and cleaning the awful odors in indoor air. Activated Carbon Filters are the most widely used type of filter to remove gases, odors, and chemical toxins. The carbon that is contained in activated carbon filters is basically charcoal. When charcoal is treated with oxygen, millions of tiny pores between the carbon atoms are created, enabling the activated carbon to adsorb odorous substances from gases or liquids.
The term "adsorb" refers to the process by which the material attaches itself to the charcoals by way of chemical attraction. Large surface areas with tiny pores of activated charcoal attract odors, gases, and chemical toxins, and the pores trap these impurities. As the carbon filter becomes full with airborne contaminants, the charcoal becomes less effective, requiring replacement. Impregnated carbon filters contain an additional chemical (a chemisorbent), allowing them to eliminate Volatile Organic Compounds (VOCs) as well as odors and fumes.
AllerAir Air Purifiers offer a variety of air cleaners especially equipped to remove VOCs, offensive odors, smoke, and smog. With an optional UV light to kill bacteria and sterilize the air, the Allerair air purifiers are comprised of an all-metal housing that does not produce off-gassing or ozone. Allerair air purifiers offer heavy-duty air cleaning for industrial or residential settings.
HEPA (High Efficiency Particulate Air) filters, by definition, are required to filter at least 99.97% of all airborne particles as small as 0.3 microns, including dust, pollen, and pet dander. However, the size, material, and construction of the HEPA filter media will determine the amount of particulates that will be filtered. If the filtration media is too small, some ultra-fine particles like foul odors and chemical fumes can be missed.
To tackle odor control, HEPA air purifiers usually combine the HEPA filter with additional filtration systems. Manufacturers like Austin Air combine the HEPA filtration technology with their own carbon/zeolite filter to effectively remove airborne pollutants and lingering odors and smells. The carbon/zeolite filter is impregnated with potassium iodide for enhanced removal of chemically reactive gases, providing your home with air thats free of allergens, toxins, and odors.
Charged Media filters are also effective against nasty odors. Through the use of electrostatic energy and synthetic fiber filters, many charged media filters can collect particles as small as 0.1 microns. The media filter, made from synthetic fibers, is charged through the manufacturing process and attracts airborne contaminants electrostatically before trapping them inside the fibers of the filter.
However, charged media filters lose their charge frequently and become less effective after every use, requiring a filter replacement to regain efficiency. In fact, some charged media filters emit ozone, a dangerous lung irritant that pollutes your air and should be avoided by allergy and asthma sufferers.
Some air purifiers like the Blueair air purifiers, offer optional smoke, odor, and gas removal filters. Known for their stylish and sleek design, Blueair air purifiers offer low energy consumption and easy-to-replace filters. With either a Smokestop filter or a particle and gas filter, Blueair air purifiers remove 99.97% of particles at 0.1 micron, and they dont emit ozone.
Like charged media filters, Electrostatic Precipitators use electrostatic charges to safely clean air and neutralize odors. As air is pushed through many static prone fibers, electronic cells charge airborne particles and capture them inside of collector plates. As electrostatic precipitators dont require filters, you dont have to worry about replacing the filters. Simply wash the collector plates and insert back into the air purifier to receive fresh, clean air.
So if youre trying to rid your home of disgusting odors, noxious gases, or foul fumes, dont spray air fresheners that will only contribute to your indoor air pollution. Instead, freshen your air with a quality air purifier. Your nose will appreciate it!
