OVERVIEW This filter utilizes an activated carbon block, designed to prevent the propagation of germs, and eliminate odor, bad taste, and color matter melted into your water. HOW IT WORKS Positively charged and highly absorbent carbon in the filter attracts and traps many impurities. DETAILS Removes biological contaminants and heavy materials, ensuring consistent pure taste. Provides final scrub of any remaining odors. There are two filter types of filtering capabilities. Granular activated carbon filtration is generally effective at filtering aesthetic contaminants, those that affect taste or smell, and VOCs (volatile organic compounds). Solid block activated carbon filtration is more effective at filtering biological contaminants and heavy metals including lead and mercury. COMPLIANCE Manufactured from FDA compliant materials. This cartridge is suitable for water purification in all home, commercial, and foodservice applications.
