Have you ever seen your water filter technician change the RO and other filters in your water purifier?You must have noticed that one of the critical filters is the ‘Activated Carbon’ filter. activated carbon pellets supplier These filters can remove the bad odours from the water and make it tasty to drink.

In the absence of this filter in the water purifier, the RO water would not have any taste at all. In fact, it can smell awful as well depending on the input water source.These ‘Activated Carbon’ filters can purify the air in the same way.

As the name suggests, these filters contain activated carbon. Activated carbon is a granular or powdered piece of carbon treated to be extremely porous.

The more porous the carbon, the more effective is the filtering capacity. In fact, one gram of activated carbon can occupy a surface area of approximately 100 acres. It should now give you an idea about the filtering capacity of activated carbon.

Carbon filtering envisages the use of a bed of carbon to remove impurities and harmful contaminants using the ‘Adsorption’ technique.The adsorption process involves the chemical reaction between the volatile organic compounds present in the air with the activated carbon whereby they stick to the filter. ningxia yongruida carbonThe reaction with Oxygen opens up millions of pores capable of trapping a significant amount of gas and bad odour. Therefore, the porosity of the activated carbon filters is directly proportional to the filtering capacity.These activated carbon filters can remove these following hazardous impurities.

Volatile Organic Compounds

Smoke and other gases



Herbicides and Pesticides


Therefore, the air passing through these filters become pure and healthy to breathe. The HEPA filters and the PM 2.5 filters can obstruct physical particles from passing through them.The Activated carbon filters complement these filters beautifully by ensuring that the volatile organic compounds and other gases do not pass through as well.

The latest air purifiers on the market come with ‘Activated Coconut Carbon Filters.’ These filters are handy as the activated carbon from the coconut shell has pores in the micropore range (approximately 85% to 90%).

It is in contrast to the other sources of carbon such as wood or peat that have pores in the macro and mesopore range. Therefore, these activated coconut carbon filters can trap the pollutants comfortably.Also, these filters have a tight structure that gives it good mechanical strength and hardness.
