![]() When buying an activated carbon air purifier, you should choose a filter with a large amount of activated carbon when we evaluate activated carbon air purifiers, we look at the size in lbs. It can also remove VOC (Volatile Organic Chemicals), solvents, radon, THM (trihalomethane), benzene, Nitrogen dioxide, chlorine, herbicides, pesticides, and many other manmade gasses.īelow is a chart that rates the activated carbon filter’s performance on its ability to remove the following contaminants:Ĭhoosing the Right Activated Carbon Air Purifier Most fumes from household cleaners, cooking, and organic odors can be removed or reduced by activated carbon filters. ![]() Type of Air Contaminants Activated Carbon Air Filters Can Remove ![]() These air purifiers can also remove perfumes and household cleaning chemicals, making your house fresher and breathable for the elderly, children, babies, asthma sufferers, and people in general. People with MCS (Multiple Chemical Sensitivity) will benefit from these air purifiers because they can absorb formaldehyde found in furniture upholstery, wood paneling, and carpet. In several models of air purifiers, the carbon is impregnated with potassium iodide and mixed with impregnated active alumina for the absorbent qualities to increase. Zeolite can act as a chemical sieve and a filer for absorbing molecules and ions. source Activated Carbon Filter Used in Air PurifiersĪctivated carbon is frequently combined with other minerals like zeolite in air purifiers. Through the help of nitrogen gas adsorption, it is determined that only 1 gram of activated carbon usually has a surface area of 500 square meters or 1/10 the area of a football field, and 1 pound of activated carbon has 200 miles of fissures and pores with an area of 4 million square feet.Īctivated carbon, especially the granulated one combined with the packed tower aeration method, is recognized by EPA (United States Environmental Protection Agency) to remove carbon tetrachloride from drinking water to below 0.005 milligrams per liter or 5 ppb. ![]() To make it available for chemical reactions and adsorption, carbon is also processed to have a huge surface area and make it very porous. Charcoals used in making activated carbon are made by burning coconut husks, nutshells, hardwood, and other carbon-based materials. The added charge makes it more attractive to impurities and chemicals that are negatively charged. It is a form of carbon that has a small charge of electro-positive added to it. What is Activated Carbon?Īctivated carbon, also known as activated charcoal, is derived from charcoal. It is also used to remove residual dyes and medications like antibiotics. It removes dissolved organic molecules, chloramines, chlorine, and some heavy metals. In the aquarium industry, activated carbon is currently one of the most effective adsorbents and the largest-selling maintenance product. People have used it for centuries to filter impurities from drinking water. The use of carbon filters for water purification is considered the oldest method of water purification. If you are not an owner of a water purification system or an aquarium, you might be surprised how activated carbon is used as an air purifier filter.
