Activated carbon filters are small pieces of carbon, typically in granular or powdered block form, that have been treated to be extremely porous. It is so cavernous, in fact, that just one gram of activated carbon can easily have a surface area of 500m2 or higher. Vast surface area enables these carbon filters to adsorb exponentially more contaminants and allergens than traditional carbon.granular activated carbon price
Adsorption is a distinct process where organic compounds in the air or water react chemically with the activated carbon, which causes them to stick to the filter. The more porous the activated carbon is, the more contaminants it will capture. These filters are most notably used to remove hazardous compounds in home air purification systems.
Carbon filters also help eliminate unpleasant odors so your indoor air remains fresh. Used together, activated carbon and HEPA filters can trap 99.97% of small particles 0.3 microns and higher as well as most larger particles, especially spores. Activated carbon filters can particularly benefit people who suffer allergies or aggravation from impure air, including second hand smoke. If you are or live with a smoker, using an activated carbon filter in your home air purification system can provide unparalleled benefits to your respiratory health.
Although a filtration system that uses chemical reactions to decontaminate air may sound complicated, it is actually rather simple. Activated carbon is typically sold in thick or thin packets for air filtration. It is then inserted into the main purifying device, such as an air purifier or HEPA air filter.
Contaminated air enters the filtration system, passes through the active carbon, undergoes adsorption, and leaves the filter purified. If used in conjunction with a HEPA filter, the activated carbon works to prevent larger particles like dust and lint from reaching it, enabling the HEPA filter to perform better and last longer.ningxia yongruida carbon co. ltd
