Disposable Odor, Fume & Gas Adsorption Air 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 homes and work places, 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 or zeolite, are widely recognized as an effective methods 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. 

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.

Air filters are available in pleats, panels and high density granular carbon packs, as well as bulk carbon and v-bank replacement trays.    High density carbon,  alumina, and potassium permanganate is available for removing light gases like Ammonia, Formaldehyde, Hydrogen Sulfide  and Sulfur Dioxide.  These products are available in odor adsorption only,  a 3-stage particulate plus odor adsorption combination, granular in a honeycomb style frame, bulk replacement carbon and v-bank housing trays.

Particulate plus odor/fume/gas removal is also available in our DustPlus® 2" model. This unit has a permanent/washable  polypropylene front panel and an interchangeable back panel enclosed within a 2" steel frame with wire reinforcement.
