Are you an aquarium hobbyist, or own a water purification system? If not, chances are you have no idea what activated carbon is, or what it could possibly do in HEPA Air Purifiers. Even if the concept itself isn't totally foreign, you probably still don't know exactly what it does.

What Does Activated Carbon Do In A HEPA Air Purifier?

The first time most people encounter activated carbon is in choosing HEPA air purifiers. When most customers begin searching for air purifiers, generally due to allergies or asthma, they really have no idea how they work. As they are further educated about HEPA air purifiers, however, they will learn that odors and chemicals are the cause of the vast majority of their respiratory problems. Most quality HEPA air purifiers are designed to take care of not only allergens, but also the odors and chemicals in the air as well.

How Was Activated Carbon Used Before HEPA Air Purifiers?

Oddly enough, we humans have been using activated carbon to filter water for a long time; as long as two centuries. Way back then, they already knew of activated carbon's great absorption qualities. Beginning in the early 1900's, activated carbon was produced and sold commercially in the form of a powder. Only used to remove taste or smell from water or color from sugar, we really didn't know at that point exactly what all it could do for us. Once World War I was in full swing, it was discovered that it could be used in gas masks for protecting our soldiers from the chemical agents in the air. The soldiers also used it, as did their ancestors, for water purification. By this point, commercial activated carbon had evolved from powder form to a granular form, which was the beginning of activated carbon being used in even more other ways.

What Does "Activated" Mean?

So, what is "activated" carbon, and is there such a thing as non-activated carbon? The heat used in "activating" the carbon drives the impurities out of the carbon itself, leaving places for the impurities of the water or air or whatever it is the carbon is filtering to reside. In a way, carbon can act sort of like a sponge, only instead of squeezing out its contents, one heats it out. Once the activated carbon is full, it can be reactivated by re-heating it, though this is considered to be impractical and dangerous. Non-activated carbon would basically be carbon that has stuff in it already, such as soot or charcoal.

Are There Different Types Of Activated Carbon?

Basically, yes. Though there are different types of activated carbon, and it's often described in various ways, all activated carbon is nothing more than amorphous carbon-based materials. These materials all have many holes, also known as a high degree of porosity, which cover a relatively large surface area. This is what gives the material such awesome absorbent quality, enabling it to work so extremely well in filtering both air and water.
