WHAT DOES A CARBON FILTER DO FOR WATER?

Pure water is fundamental to maintaining good health, yet many water sources contain undesirable elements. Well water frequently carries various impurities, while even treated municipal supplies may contain components you'd prefer to remove. Modern water purification typically employs multiple specialized filters, with activated carbon filters being the most widely used and efficient option. 

HOW CARBON FILTERS WORK?

While early carbon filters utilized materials like peat or bituminous coal, modern versions predominantly employ eco-friendly coconut shells as their raw material. The manufacturing process involves two critical thermal treatments: first, vacuum heating to 1,000°C to eliminate impurities, followed by steam activation at 1,600°C. This steam treatment expands the carbon's porous structure, creating microscopic fissures that dramatically increase its adsorbent surface area. The result is an exceptionally efficient filtration medium - just one pound (450g) of this activated carbon possesses a staggering surface area comparable to 100 acres, ensuring optimal contaminant removal.

The filtration mechanism operates through adsorption – a physicochemical process where impurities are drawn to and retained within the carbon's porous matrix. As water permeates through the activated carbon bed, contaminants are effectively captured while purified water continues to subsequent treatment stages. Notably, certain substances like chlorine undergo chemical conversion rather than adsorption; in this case, chlorine molecules are transformed into harmless chloride salts through catalytic reaction with the carbon surface.

There are two basic types of activated carbon filters:

Granular Activated Carbon (GAC) filters utilize loose carbon granules typically measuring 1mm in diameter. These specially engineered particles effectively capture contaminants that may bypass other filtration media. Frequently deployed as a final polishing stage, GAC filters excel at enhancing water's organoleptic qualities by removing residual tastes and odors.

Carbon block filters are manufactured by combining carbon granules with a binding agent, which are then heated and compressed into solid blocks. This compact structure enhances filtration efficiency by immobilizing the carbon particles, though it may result in slower flow rates-particularly with finer micron ratings that provide superior contaminant removal.

THE CONTAMINANTS THAT ARE REMOVED

Activated carbon filters are highly effective at removing a wide range of water contaminants, including up to 95% of chlorine used for disinfection that can cause unpleasant tastes and potential health issues. They also eliminate over thirty chlorine byproducts like VOCs and THMs, along with fourteen common pesticides and twelve frequently used herbicides. These filters can reduce up to 90% of lithium, a trace metal with possible health risks, as well as pharmaceutical residues that enter water sources and PFOS chemicals known for their commercial applications but potential human health hazards. Ensuring your family's access to clean, safe water is essential, which is why our water treatment systems combine multiple methods, including activated carbon filtration, to deliver pure, fresh water. We provide water testing services to identify specific contaminants and recommend the most appropriate filtration system for your needs.
