GermAway Large Room Activated Carbon Filter
Activated Carbon Filter: Once we get rid of the large airborne particles that are trapped by the pre-filter and the small particles that are stopped by the HEPA filter, the next problem is chemical and organic contaminants. The biggest and most harmful iteration of these are Volatile Organic Compounds (VOCs).
he good news is that activated carbon filters have a pretty good track record of neutralizing VOCs. The pollutant organic molecules get trapped into the carbon structure's pores in a process called "adsorption". Once the VOCs are adsorbed into the microporous structure of the activated carbon, they will stay there and out of the air you breathe.
Note: it is important to replace the activated carbon filter regularly (every 6-12 months depending on the usage) because unlike mechanical filters that will continue to work as long as they have regular cleaning, the activated carbon must be replenished in order to keep providing area for the polluting substrates to adsorb to.
