What is the use of charcoal in a purifier?

Charcoal is commonly used in purifiers as a filtration medium to remove impurities and contaminants from water or air. Charcoal has a porous structure that allows it to trap and absorb various pollutants, chemicals, and odors. When water or air passes through the charcoal filter, the impurities are trapped within the pores of the charcoal, resulting in cleaner and purer water or air. Charcoal is particularly effective at removing chlorine, volatile organic compounds (VOCs), and other harmful substances from water and air.

Adsorption:

- Charcoal is highly porous and has a large surface area, providing numerous sites for impurities to adsorb onto.
- Impurities such as chlorine, pesticides, heavy metals, and organic compounds are attracted to and cling to the surface of the charcoal.

Filtration:

- Activated charcoal acts as a filter, trapping contaminants that are larger in size.
- These contaminants can include sediment, rust, and debris.

Deodorizing:

- Charcoal can absorb and neutralize odors from the air.
- It acts as a strong odor eliminator, removing unpleasant smells caused by bacteria, pets, cooking, or other sources.

Gas Absorption:

- Charcoal can absorb certain gases, such as radon, carbon monoxide, and volatile organic compounds (VOCs).
- These gases can contribute to indoor air pollution and have adverse health effects.

Water Purification:

- In water purifiers, charcoal is commonly used to remove impurities and improve water taste and quality.
- It can reduce chlorine, heavy metals, and unpleasant odors.

Benefits of Charcoal in a Purifier:

- Improves air and water quality
- Removes impurities and contaminants
- Reduces odors
- Absorbs harmful gases
- Provides a cost-effective and natural way to purify air and water
