How does the Activated Carbon Air Filter Work?
The positively charged active carbon attracts negatively charged impurities. This process is called as ‘adsorption’. The gas molecules of chemicals and other impurities get stuck in the numerous tiny pores on the surface area of the activated carbon pad, present in the filter. The amount of impurities attracted by the filter would be in proportion with the amount of carbon and its thickness. The large surface area allows more pollutants to come in the contact of the filter and hence cleans large volumes of air. A small piece of activated carbon in the carbon air filter is capable of removing impurities from the whole house. Activated carbon air filters are better than other odor removing mechanisms, like sprays and fresheners. While they only fool our senses into believing that there is no odor, the odor actually still exists. Whereas carbon filters practically eliminate the odor by capturing the impurities or gas molecules responsible for it. Activated carbon is not used as the sole f
