TRIPLE ACTION FILTRATION TECHNOLOGY: Our filters use advance carbon blocks made of active coconut carbon that purifies the water first through mechanical filtration of the waters passing through the micro-pores of the filter. Then the water is further purified through two seperate stages of ionization filtration that take place as the water passes through the carbon block to your refrigerator. This filtration process is state of the art and not something other filter brands offer. | REMOVES 26 CONTAMINANTS: PURELINE removes 26 contaminants from your water. Our filters remove 99% of Heavy Metals, Mercury, Chlorine, Odor, THM, Voc, micro-organisms, particles and 95% or Greater Reduction Rates of Cadmium, Chromium, Copper, Lindane, and all other major contaminants. | CERTIFICATION: PURELINE filters have been tested and certified by the NSF, WQA, and IAPMO. | BETTER THAN THE BRAND: PURELINE filtration technology is the most advanced in the industry making our filters better than the brand filters as well as generic filters on the market. | COMPATIBLE WHIRLPOOL FILTER MODELS: 4396508, 4396508P, 4396508T, 4396509, 4396509P, 4396510, 4396510P, 4396510T, 4396547, 4396548, 4396562, 4396563, 4396918, 4392857, 4392857R, 4392922, 46 9902, 46 9908, 9902, NL240, WSW-1, | COMPATIBLE EVERYDROP FILTER MODELS: EDR5RXD1, EveryDrop Filter 5 | COMPATIBLE KENMORE MODELS: 46-9010, 9010, 46-9085, 9085, Kenmoreclear 9010, Kenmoreclear 9085, 46-9902; 46 9902; 469902; 9902; 46-9908;46 9908 ; 469908; 9908 | COMPATIBLE KITCHENAID FILTER MODELS: 4396547, 4396548, 4396163, 4396164, 22203221, 2255709, 4396509, 4396509P, | NO LEAKAGE & 100% COMPATIBILTY: We made a filter that is designed to exact standards and fit as the GE MWF Original in order to prevent leakage that has been reported by other generic filters on the market. | PURELINE HISTORY: We were one of the first generic filters on the market.
