HEPA Filtration
HEPA Filter Camfill Farr HEPA filtration (High-efficiency particulate air) was first used by the German Army in early 1940 in gas masks. Gas masks equipped with a new special filter were captured by the British Army and sent to the US Army for testing. The first filters were made from Blue Asbestos and esparto grass and had unusually high particle retention characteristics, acceptable resistance to airflow, good dust storage, and resistance to plugging from oil-type screening smokes. These filters were primarily used for military applications involving chemical warfare agents. Nowadays HEPA filter are made of fine glass impregnated cellulose fibers, their efficacies, 99.97% efficient at particles 0.3µm(micron), are tested upon a proper procedure and upon specific norms (ASHRAE or EN 1822) . The first commercial manufacturer was AD Little company in Cambridge Massachusetts which later became known as Cambridge filter, forerunner of Camfil-Farr Company, the manufacturer of NQ500 filters.

 NQ 500 - C Activated Carbon FiltrationAlmost all odors are connected with gases, even HEPA filters have almost no ability to remove them from the air. The best solution to odor control uses a combination of adsorption and oxidation. In adsorption, most commonly using activated carbon, gas molecules wind up attached to the surface of the collection medium. Think of each granule of activated carbon as a golf ball with many microscopic dimples. The gas molecules fit into the dimples and are held there by molecular forces. The effectiveness of the adsorption process is affected by the amount of time that the stream takes to pass through the filter (residence time) as well as the density of carbon. When all the dimples are filled, the carbon is saturated and will begin to pass odors through and need replacement. Therefore, the more carbon in the filter, the longer it will last. Some odor causing molecules will not adhere readily to the surface of the carbon. Fortunately, a process called oxidation in which oxygen is added to the gas can chemically transform most of these molecules. The result is an air stream that no longer has odor problems. An oxidizer like potassium permanganate will create this reaction without generating ozone (Ozone can cause respiratory problems). The combination of activated carbon and potassium permanganate in a well-engineered blend offers the ideal solution to odor problems in an airstream. Photocatalysis - UVPCO Image published in June 2006 Popular Science magazine The air cleaning technology by Ultra Violet Photocatalytic Oxidation (UVPCO) has been studied for a number of years within the framework of the removal of organic contaminants in gas phase present into the air. This technology aroused interest with regard to the applications of interior air since many studies in laboratories showed its capacity to completely oxidize a broad range of organic compounds at ambient temperature. The UVPCO can successfully be applied in the buildings to reduce concentrations of Volatile Organic Compounds (VOC’s), as well as a broad panel of airborne pollutants. The process lies in the use of titanium dioxide (TiO2), which reacts with UV light (UVC at 253.7 nm). This interaction, in complement of air and water vapours, will create hydroxyl free radicals, which will generate an oxidation of organic materials to destroy. Unlike conventional powder TiO2 treatments, NQ Industries has utilized a new, cutting edge technology using TiO2 on a molecular level, which eases the installation and maintenance of the TiO2 compound, and thereby extending it’s deployment life by a factor of 4 above any other type of compound in the market today! This process has been used successfully for several years for cleaning surfaces such as historic buildings, panes or frontages of buildings. NQ Industries Inc. has introduced this new, cutting edge technology in 2006 in order to increase the efficacies of NQ systems upon certain VOC’s, odours or chemical pollutants that have to be treated.
