Did you know that coconut shell carbon has a significantly higher porosity than other forms of activated carbon? It has up to 50% more micropores than bituminous coal. Due to this, it can absorb contaminants and volatile organic compounds, which is why it's considered one of the most optimal materials for water filtration purposes.
Essentially, this means that coconut shell carbon is the preferred carbon to remove volatile organic compounds (otherwise known as VOCs) from drinking water point-of-entry systems (otherwise known as POE systems). Conveniently, it also removes foul odors and bad tastes from drinking water, which is why coconut shell carbon is commonly used in water filters.
