Activated carbon comes from charcoal, which is made when organic materials are burned, and might just be one of the longest used types of filters.

This type of air purifier has been known to have been used as far back in history as 2,000 years ago, when it was used to remove impurities and toxins from drinking water.

Then around the time of World War I it was discovered that activated carbon could be placed in gas masks in order to protect soldiers . coconut shell carbon Carbon has been used in commercial strength air purifiers for several decades.

As we mentioned earlier, activated carbon air purifiers work by utilizing charcoal, but this charcoal undergoes a simple process in order to make it usable for air purification.This type of filtration can absorb up to 60% of its weight in air pollutants.

Activated charcoal has been treated with oxygen in order to open up the millions of pores in between the carbon atoms in the charcoal, which is what enables the charcoal to absorb odors and fumes effectively.

They are also capable of removing organic molecules, much like solvents. coconut shell activated carbon price This is a very simple but effective means of neutralizing odors and trapping gases in the air of a space.

When the pores of a carbon filter are filled, then it is time for the filter to be replaced. Charcoal is an abundant source of carbon, so these filters can be relatively inexpensive to make, and are often used in gas masks, and chemical cleanup kits.
