How Does Activated Charcoal Work?

How Does Activated Charcoal Work?You might be wondering how a “sooty” substance can help purify air and water. There is in fact Science behind why activated carbon (or activated charcoal) has the power to remove bad smells, chemicals, and contaminants from the water and air that passes through it.

First of all let’s find out what “activated” means and why activated charcoal is not the same as the charcoal you use for cooking barbecue at home!

What does “activated” mean?

Unlike the ordinary charcoal we use for barbecue, activated carbon is processed to achieve tiny, low-volume pores to increase the surface area that allow adsorption and chemical reactions.

Activated charcoal works through adsorption

Adsorption is a process where gas or liquid molecules stick to a surface of a solid. Unlike in the absorption process, water or liquid doesn’t dissolve or become a part of the adsorbent.

To illustrate, imagine water passing through a tissue or material such as a sponge (adsorbent). The water only passes through the sponge or tissue without becoming a part of it, but filtering out impurities, leaving purified liquid.

In a similar way, activated charcoal is an adsorbent or a filtration medium, where unclean air can pass through and gets purified.The allergens or airborne contaminants chemically react to the porous surface of the activated carbon, and then stick to it. After this, clean air flows through the activated charcoal purifier, leaving behind the pollutants. 

How does activated charcoal improve air quality?

Besides removing unwanted smells and odors, activated charcoal is also an amazing remover of allergens, disease-causing microbes, and toxic fumes that may be present in the air. While the use of chemical reaction and adsorption appears to be complicated, it really is rather simple. To illustrate:

Contaminated/foul air passes through the activated carbon acting as a ‘filter’ → the air undergoes adsorption where harmful impurities stick to the activated carbon surface → clean, fresh air flows out

What sort of contaminants can activated charcoal remove?

Good quality activated carbon can trap and eliminate impurities and allergens such as:
  • mold spores
  • lint
  • dust and dust mites
  • smoke and smoke odor
  • pet hair & odor
  • household chemicals and VOCs (volatile organic compounds)
Depending on usage, activated carbon filters vary on types and sizes. Activated carbon air purifiers and deodorizers made specifically for household purposes work best in enclosed spaces such as bathrooms, bedrooms, refrigerators, closets, shoe cabinets, attic, laundry areas, under-sink storage, office, vehicles, as well as for deodorizing your personal belongings including work boots, shoes, bags, luggage, and other similar items.

If you want to get rid of bad smells and allergens that are potentially harmful to your health, activated charcoal air purifiers are the safest and most natural alternative to keeping your home clean and fresh all the time.

Unlike most shop-bought room deodorizers, they only mask the odor and don’t really eliminate the odor itself. What’s disturbing is that typical household deodorizers are generally chemical-based. So instead of helping you to improve home health and safety, they can even potentially cause long-term health effects.

Thanks to air deodorizers and purifiers made from 100% organic activated carbon, we now have a much safer alternative to commercial household deodorizers.

Start removing unwanted impurities and odors from the air inside your home safely and naturally by using activated charcoal purifiers today.
