Odor Filter and Activated Carbon | Odors & Fume Removing Filters
An estimated 4 million chemical compounds exist in
the environment. About 63,000 commonly used in America, and another
1,000 or so are being synthesized every day. Some healthy, some
harmless, and some highly toxic. Chronic chemical
sensitivity, have become widespread. Roughly 4-5 million
Americans already suffer from the effects of chemically induced
environmental illnesses. Numerous health threats include risk of
cancer, respiratory illnesses and eye, skin and throat
irritations. These illnesses lead to absenteeism, reduced
productivity, increased insurance rates and sometimes liability and
litigation. Studies show that the air in our home and
work place is now commonly more polluted than outside air - up to
10 times as dirty - with some pollutants reaching concentrations
that would be illegal in the atmosphere. Contaminants quietly
emanate fumes ("off-gassing") into room air.
Activated carbon is widely recognized as an effective method of removing and preventing odor/fume buildup in recirculated air. Utilizing the finest quality coatings, Permatron offers a line of high efficiency odor/fume and gas removing air filters, bulk media and pads cut to size. Activated carbon, mixed with Alumina and Potassium Permaganate is highly effective for organic odors and light gases like Ammonia, Formaldehyde, Hydrogen Sulfide and Sulfur Dioxide. 1" pleated type filters have approximately 3X the effective media surface of a 1/4" panel filter.
Synthetic media substrates are impregnated with finely ground coatings, such as activated carbon, zeolite or alumina, and heat set to retain those coatings even when the media is rinsed or vacuumed. Just as a sponge soaks up water, activated carbon media adsorbs odors and fumes. The odor causing molecules are actually removed from the air permanently, not masked with another odor. Activated Carbon is highly effective for organic based odors. Activated carbon and alumina with potassium permanganate is highly effective on light gases.
Air velocity, humidity and temperature can influence the odor elimination. At times of high odor generation, air should recirculate through the filter to achieve maximum effectiveness. The rate of adsorption depends on the relationship between the pore structure, or surface area, and the shape of the contaminating molecules. Activated carbon filters are disposable. Once they are saturated with odors/fumes, approximately every 3-6 months, they must be replaced.
