Carbon Filter – The Ways Carbon Matters in Filter Performance

Carbon filter is used in carbon filtering where the system uses a piece of the activated carbon to eliminate impurities and contaminants, using chemical adsorption. When the material soaks something, it bids it to via chemical attraction. The big surface area of the activated charcoal enables many bonding sites to form.  This carbon is usually activated with the positive charge and is developed to attract the negatively charged water contaminants. The article presents how the filter media of the carbon filter, i.e. the activated charcoal, impacts the performance of the carbon filter.

The Amount

The activated carbon absorbs through its surface. When no more surface is left to further absorb to the carbon, it capacity is reduced. Huge amount of carbon lasts longer than smaller amount since it possesses a higher surface area for the adsorption. In addition, based on the pollutant percentage being adsorbed, a little amount of the carbon can be consumed within a few weeks, which makes it useless.

The Thickness

The more the contact time of carbon is with the pollutant, the better adsorption it exhibits. The thicker the carbon filter, the higher the adsorption rate is. If the pollutant goes through a long maze of the activated carbon, there are higher chances for it to be adsorbed. It implies that thin carbon filters fitted in the inexpensive air purifiers may not be effective as required, at removing fumes, chemicals, and odors from the air.

The Coconut Shell Activated Carbon

The coconut shell carbon offers more hardness, which makes it cleaner than most of the other carbons and more long lasting. This, along with higher activity level, makes them highly suitable for all kinds of carbon filter. Apart from the general level of air purification and deodorization, the coconut shell carbons also show a superior performance in solvent recovery applications as well as in many industrial settings.
