How Activated Carbon Is Used In HEPA Air Purifiers

For most people, though, the first time they encounter activated carbon will be in choosing HEPA air purifiers. Most customers begin their search for air purifiers due to asthma or allergies. As they learn more about HEPA air purifiers, though, they'll learn that many of their respiratory problems come from chemicals and odors in the room. Therefore, most quality HEPA air purifiers are designed to address the chemicals and odors as well as the allergens themselves. This is where the activated carbon comes in. It's job, as part of the HEPA air filter, is to filter out those odors and chemicals – basically by absorbing them. Notice, though, that I said quality HEPA air purifiers. There are many that do not even address the issue of odors and chemicals, and so going just by the text on the box or online summary, you may not have even known this was something air purifiers could do.
