For many people, the first time they encounter activated carbon is during the process of selecting home air purifiers. Although most of our customers begin their search because of allergies or asthma, many soon learn how odors and chemicals can contribute to respiratory problems. To that end, many quality room air purifier systems offer a comprehensive solution to these issues. History and Use in Purification Processes As many as 2000 years ago, human beings used activated carbon to remove impurities from water. Even then, its exceptional absorption qualities were known. However, it was not until the early 1900s that activated carbon was produced in powder form that could be sold commercially. At that time, it was used to purify water and to remove the color from sugar. As World War I progressed, it was discovered that activated carbon could be used in gas masks to protect soldiers, in addition to cleaning wartime water and in the manufacturing of air purifiers. It was during this period that granular activated carbon was developed.

Why Is It Called "Activated?" You may find yourself asking why activated carbon is called "activated" and whether there is non-activated carbon, as well. The heat used in the process of changing carbon to an "activated" state drives out impurities; there are places for your air impurities to reside when it is used in an air purifier. After activated carbon has been used, it can actually be reactivated by heating it again. However, the reactivation process is impractical and dangerous. hitachi air purifier epa 7000 reviewNon-activated carbon is soot or charcoal.ecoquest air purifier consumer reports Activated carbon is described in a variety of ways, but generally the range includes amorphous carbon-based materials that exhibit a high degree of porosity and an extended surface area. advanced pure air newport 9000 air purifier manual

This simply means that it has excellent absorbent characteristics that make it very useful for a wide variety of filtration processes, including air and water. How Is Activated Carbon Used in Home Air Purifiers? In room air purifiers, the activated carbon is often combined with other minerals, like zeolite. Zeolite can absorb ions and molecules and thus act as a filter for odor control, toxin removal, and as a chemical sieve. In some air purifiers, the carbon may be impregnated with potassium iodide or blended with active alumina to increase absorption qualities. These home air purifiers are particularly helpful to people with Multiple Chemical Sensitivity (MCS), because they absorb formaldehyde, a compound found in carpet, wood paneling, and furniture upholstery. Perfumes and chemicals in household cleaning items are also removed, making the environment much more breathable for all, especially asthma sufferers, babies, children, and the elderly. The Carbon in Room Air Purifiers

The type and amount of activated carbon and how it is used in home air purifiers depends on the brand and model. Here are the highlights: Austin Air Healthmate Plus Air Purifier The Austin Air Healthmate Plus air purifier contains 18 pounds of granular activated carbon impregnated with a blend of zeolite and potassium, making it effective at removing formaldehyde and other harmful chemicals.
