VOC FILTER REPLACEMENT: Designed to fit all standard 10-inch housings for under sink home water filtration, this filter is specifically formulated for the reduction of VOCs, filtering particles as small as 1-micron. HIGHLY EFFECTIVE FILTRATION: Includes one 1-Micron VOC Carbon Block Post-Filter (WP101013) with a flow rate of 0.5 GPM (1.89 lpm). Made with high quality, NSF-certified coconut shell activated carbon, this filter reduces a range of impurities. TASTE ENHANCEMENT: In addition to removing VOCs, this filter improves the taste of water and removes unwanted odors. Water enters this filter after the storage tank and acts as a final filter to crispen up the flavor and enhance the taste of your water. QUALITY CONSTRUCTION: This durable filter is crafted from high-quality materials for maximum filtration. Filter life may vary based upon local water conditions or use patterns, but we recommend replacing the VOC Carbon Post-Filter once a year. THE PREMIER DIFFERENCE: Since our founding in 1989, Premier has been dedicated to the design, development, and marketing of high-quality water filtration systems that exceed industry standards.
