Activated Carbon filter, or charcoal filter, is a bed of activated carbon typically in granular or powdered block form, and consists of millions of tiny absorbent pores. This air filter has been treated to be extremely porous, and this is the popular filtration against gases, chemicals and Volatile Organic Compounds (VOCs). However, the Activated Carbon filter can’t remove fine particles like dust, dust mites, pet dander or pollen from the air.

The Activated Carbon filter is originally called HEGA (High Efficiency Gas Absorption) filter, and first being used by the British Army in the chemical warfare.coconut activated carbon suppliers  It removes the gas molecules through a process of adsorption (not absorption). During adsorption, the pollutants stick to the outside of the Activated Carbon filter.

In air purifiers, the Activated Carbon filter is mostly used in conjunction with the HEPA filter to capture the other tiny particles as well, like dust, lint, mold spores, pet dander and pollen. You will find in the high-quality Activated Carbon filter to have potassium permanganate or potassium iodide to remove the chemicals, formaldehyde and wildfire smoke much better.

The Activated Carbon filter is a very important air filter in all the air purifier systems, but it can only last for a short time. Typical Activated carbon filter (or Charcoal filter) can only last between two and four weeks, then you need to vacuum or clean the air filter before using it again. The Activated Carbon filter needs to be changed every few month to be efficient. This is because of the adsorption process that increasingly fill up the pollutants inside the activated carbon bed. Once the bed is saturated, the filter can no longer be capable of taking in pollutants more.www.chinactivecarbon.com

Can Activated Carbon be reused? The simple answer is yes, because of the porous nature of activated carbon, this air filter can be recycled by baking out the odors of it, then you can reuse the air filter completely. However, you can only reuse the Activated Carbon filter two to the maximum of three times, then you must replace the carbon filter so it can work against the smoke, odors and chemicals.
