“ASPA” – make ACTIVATED CARBON FILTERS How activated carbon is made? Most active carbon, as used for gas or vapor trapping, is made from coconut shell. The shells are heated to over 2,000°C under high pressure, which causes fissures on the surface of the carbon, creating a high quality, small pore activated carbon. The fissure system is extensive, creating a very large surface area in a small package, and it is in these fissures that other gases and particles are trapped. A single activated carbon filter has a flattened surface area of a football field and can absorb up to 60% of their own weight in gases! How does activated carbon remove odors? Activated Carbon has the ability to capture gas molecules and hold them. The accumulation of molecules of a gas to form a thin film on the surface of a solid is called adsorbtion. The carbon surface is made up of millions of tiny pores, the gas and odors fall into these pores and are trapped there until the pad is recharged or disposed. Other methods to get rid of odors such as sprays & deodorants, only fool you sense of smell - the odors still exist. Activated carbon air filters are the most effective type of filter against chemicals, gases, cigarette smoke and other odors. (list mentioned) Activated carbon air filters consist of a vast system of pores of molecular size. These pores are highly adsorbent, forming a strong chemical bond or attraction to odorous, gaseous, and liquid contaminates. Activated Carbon Filtration is commonly used in water and air purification. HVAC applications, which require the removal of odors include air filtration and air purification in medical, pharmaceutical, electronics, semiconductor, hospital, and oil-free environments.
