The right amount of airflow allows for enough dwell time so that the media can remove as many pollutants as possible. In contrast, during adsorption, the adsorbed substance chemically attaches to innumerable micropores in the adsorption site.įor comprehensive odor and VOC filtration, the airstream shouldn’t pass through the carbon filter too fast. The way water seeps into a sponge would be a good analogy for this process. During absorption, whatever is being absorbed never becomes chemically bonded with the absorbent. Adsorption causes filtered pollutants to stick to the sorbent and remain there.Īdsorption is completely different from absorption. Instead, a charcoal filter gets rid of unpleasant odors and gaseous pollutants through a chemical process called adsorption. Unlike HEPA, this isn’t a mechanical filter.
