BYB Pearl Water Technologies produces pre-carbon filters as water filtration devices which extract impurities before letting water proceed to the main filtration setup. The filter contains activated carbon which acts as a trapping agent for chlorine and bad odors together with chemical substances thus producing clean water with better taste. The pre-carbon filter operates at the first stage of filtration to defend additional filters as it enhances general water purity. join us https://pearlwater.in/ro-filte....r-kit/pearl-water-ca
