<h1>Carbon Air Filters: Proper Use, What They Do–and Don’t Do</h1>

Carbon has been used for a long time to remove chemical and gas type pollutants from the air. And when used properly and replaced regularly, they can be invaluable for keeping indoor air free of these types of pollutants. By one or more activation processes, usually by heat or chemical means, small granular or crushed carbon bits are given an increased attraction to chemicals, vapors, and other similar airborne residues, so that, in theory, when air passes by, these pollutants stick to the surface of the carbon, and allow only clean air to pass. There are several things to keep in mind, however, when using or relying on carbon filters to keep the air clean.

 

First, the type of pollutants in the air affects how well activated carbon filters can remove them, and all activated carbon can remove or ‘adsorb’ different pollutants at different efficiencies, i.e. 40%, 80%, 90% etc. For normal household use, a standard activated carbon filter will work pretty well and adsorb the majority of pollutants. For industrial use, however, it’s important to check with the carbon filter manufacturer to see how well their carbon will remove the pollutants in the work area; otherwise, you could actually cause more of a hazard buying a carbon filter air purifier that is doing more circulating of polluted air without cleaning it. A few companies, such as Electrocorp, actually offer custom carbon blends that efficiently remove specific pollutants so that doesn’t happen. Keep in mind, too, that cheap activated carbon doesn’t always work as well as premium or military grade—which can leave harmful pollutants in the air, plain and simple.

 

Carbon air filters are not HEPA filters are not much good at stopping or removing particles, dust or fibers, so if that’s needed in your situation, make sure the air purifier has a HEPA filter as well. Charcoal air filters, even those with military or premium bulk carbon, all become saturated with the chemicals or gases they are removing, and when saturated, the air purifier will simply allow polluted air to pass or be circulated without cleaning it, which again, can create a potentially costly health hazard for your home or business.

 

The obvious way to avoid that problem is to replace the carbon filters on schedule, a little before, when you smell odors again, or when hazardous chemicals are involved, when detectors show the presence of airborne chemicals again. Properly using carbon filters and replacing them appropriately can make a huge difference in air quality, safety, productivity and more—but used improperly or not replaced adequately, can actually increase problems.
