The process of air purification with an activated carbon filter works like this:
- Contaminated air enters into the filtration system.
- The air passes through the activated carbon air filter.
- The process of adsorption takes place to remove the contaminants.
- Purified air flows out of the activated carbon filter and back into the room.

What is the difference between a charcoal filter and a carbon filter?
What is the Difference between an Activated Carbon Filter and a Charcoal Filter? The primary difference between a water filter that uses activated carbon and one that uses charcoal is in the filtering materials themselves. Both are hard, porous substances that capture contaminants.
A pollution and health problem
All enclosed spaces, be they rooms of an apartment or the environments of factories and industries, are prone to air pollution. It is an inevitable process as the air surrounding us is polluted, contaminated by smog, dust, bacteria, and various allergens.
Operation and characteristics of activated carbon for air purification
A useful and effective way to purify the air at an industrial level is the activated carbon filters. The activated carbon, in fact, has adsorption capacity, such as being able to retain most of the substances and organic compounds present in the air.
Air purification: the reference industrial sectors
For industrial air purification, it is essential to choose the best-activated carbon according to the substances that need to be adsorbed. It is because activated carbon is not all the same; depending on the type of material intended to be adsorbed, air purification systems differ from each other with respect to their applications.
Food and catering industries
The food sector is one of those that most needs filters and air purification devices. The cooking of various foods and foods, often continuous and at high temperatures, produces fumes and odors that clog the work environment. It has effects both on the livability of the environment and on the quality of food production.
Cosmetics industries
The cosmetics industry deals with producing products and articles for body care and personal hygiene. The production processes are highly delicate, with the emission of large quantities of toxic substances into the air.
Mechanical and carpentry shops (workshops & assembling units)
In carpentry shops, where there is the use of varnishes, paints, glues, and products with solvents, activated carbon filters are indispensable for air purification, even with regard to mechanical body shops, where the use of sprays and coloring products is continuous, the health of workers and the environment.
Steelworks
Steel centers in general and those dealing with steel production, in particular, require highly efficient air purification. It is to prevent fumes, dust, and other pollutants from being emitted into the atmosphere and causing serious damage to the environment.
What is activated carbon?
Activated carbon is a potent adsorption material that draws foreign or unwanted particles into it thereby removing them from the original medium - be it water or gas like the air. The unwanted particles stick, or adhere, to the carbon surface - almost like the carbon 'grabs' them from the air or liquid they are in.
How does a carbon filter work?
The filter works in an organic way whereby the contaminants react chemically with the activated carbon and stick to its vast surface area. One of the most common ways to use these filters is within the home environment where they purify the air and keep it smelling fresh and hazard-free.
What is the difference between a carbon filter and a HEPA filter?
This helps to keep the air free from harmful contaminants and smelling fresh and clean. HEPA filters are designed to remove up to 99.9% of the particles in the air while the carbon filter serves to remove the oils, bad smells, and gases, such as smoke, from the air.
Why are carbon filters processed at high temperatures?
These are processed at high temperatures to increase the surface area of the carbon and are used in the manufacture of filters that purify the water and the air.
Why does my air smell bad?
Most bad smells in the air are caused by oils, such as the smell of fried fish or pet odors. These oils can be adsorbed into the activated carbon and removed from the air which also removes the bad smell. The oils in the air stick to it and the air ends up smelling fresh and clean. The same principles apply in water.

You’ll find studies showing how carbon can get rid of strong odors and gases that can harm your health. The rest can be experienced through trial and error, and luckily there are plenty of reviews on air purifiers and activated carbon products if you’re hedging your bets.
What is activated charcoal?
Activated charcoal (or activated carbon) is charcoal that underwent an additional heating step in the manufacturing process. This essentially cleans the charcoal of its impurities. It increases its surface area and creates more micropores, making the charcoal even more effective at trapping odors.
Why is carbon used in emergency rooms?
In emergency rooms, carbon is used to treat drug overdoses and adsorbs the toxins to prevent death.
What is bamboo charcoal used for?
Being called the “black diamond” during the times of the Chinese Ming Dynasty, it was used to purify water, air and remove toxins in the body and on the skin.
How long should I leave charcoal in the sun?
Typically, one hour outside once a month will clear up the pores and make the charcoal ready to be used again, but it depends on the charcoal product that you’re using. Direct sunlight isn’t necessary as the charcoal only needs UV light to recharge.
How to neutralize a bad smell?
Rather than just masking the odors, the odors need to be neutralized. One way to achieve this is by using charcoal. Instead of just masking the odor, charcoal actually removes the smell by adsorbing the harmful particles from the air, not by covering the bad smell.
Why don't people know what's in air fresheners?

Select activated carbon with strong adsorption capacity
Not all activated carbons have the same adsorption effect. Only those activated carbons with a large number of pores slightly larger than the diameter of harmful gas molecules have strong adsorption capacity.
Reasonably place activated carbon indoors
Personally, I think that the activated carbon should be placed in the most polluted place, such as the wall cabinet in the room, behind the sofa in the living room, etc.
Regular release of harmful substances in activated carbon
Harmful gases are often only adsorbed in the activated carbon without being decomposed. Therefore, after using activated carbon for a period of time, the activated carbon should be exposed to the sun to release some toxic substances.
Fourth, replace the activated carbon in time
The adsorption of activated carbon will be saturated. At this time, activated carbon not only has no adsorption effect, but may also release toxic substances in it. If the indoor pollution is serious, it is best to discard the activated carbon after 2-3 weeks of use.
