This filter is effective in reducing free chlorine, bad taste, odor, THM, organics, hazardous chemicals, and more. Depending on the source water quality or flow rate, it needs to be replaced every 6 months or about 50,000 gallons of water. Each filter is individually sealed to keep it fresh.

This highly activated carbon block CTO (Chlorine, Taste, and Odor) filter cartridge is designed and produced using high-quality coconut shell carbon and highly compact fabrication technology to achieve maximum filtration efficiency and filter life for 10" Under Sink Water Filter and Whole House Water Filtration Systems. It is free of surfactants, binders, and adhesives, and there is no leaching of carbon ash.

The filter's exceptional filtration performance knocks out cloudiness, as well as bad tastes and odors, and removes up to 99% of chlorine. It is highly effective on organic compounds like herbicides and industrial solvents, as well as other contaminants like trihalomethanes. It delivers a steady flow and high absorption.

The filter can filter up to 50,000 gallons of water, depending on the use and feed water quality. For optimal performance, it should be replaced every 6 months or every 50,000 gallons of water.
