Home Air Quality refers to pollutants that typically occur indoors such as Volatle Organic Compounds, as opposed to outdoor air quality Formaldehyde and voc Indoor air polution can be categorized into aerosols and gasses. Some like Formaldehyde and VOCs (volatile organic compounds) viruses in the air are actually small water droplets (aerosols) containing the virus. Activated carbon, also called activated charcoal Organic chemicals are attracted to carbon the best. Very few inorganic chemicals will be removed by carbon. Chlorinated volatile organic compounds (Cl-VOCs), including polychloromethanes, polychloroethanes and polychloroethylenes, are widely used as solvents VOCs Benzene, Ethylene glycol, Formaldehyde, etc Odors Fine smoke particles.

Activated carbon has special properties that allow it to remove volatile organic compounds (VOCs), odors, and other gaseous pollutants from the air. Carbon air filters are the filters most commonly used to remove gases. They are designed to filter gases through a bed of activated carbon (also called activated charcoal) and are usually used to combat volatile organic compounds (VOCs) released from common household products. They are also often used to remove odors from the air, such as the smell of tobacco smoke. They cannot remove fine particles like mold, dust, or pollen from the air. Outdoor air pollution. ______________________________ The EPA Indoor Air Quality (IAQ) publications do not list specific chemicals but have general guidelines such as:

ResearchGate developed an IAQI (Indoor AQI) chart using EPS's Outdoor component list.

In this paper, index for indoor air quality (also known as IAQI) and thermal comfort index (TCI) have been developed. The IAQI was actually modified from previous outdoor air quality index (AQI) designed by the United States Environmental Protection Agency (US EPA).
