TRIPLE ACTION FILTRATION TECHNOLOGY: PURELINE filters use advance active coconut carbon blocks that remove the impurities from your drinking water in three different stages. First the water passes through the micro-pores of the filter, which removes the larges sediments and metals. This is known as mechanical filtration. Then the water is further purified through two separate stages of ionization filtration that take place as the water passes through the carbon block to your refrigerator. | REMOVES ALL 26 MAJOR CONTAMINANTS: PURELINE 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. | NO LEAKAGE & 100% COMPATIBILTY: PURELINE's Research and Development Team has not only invested heavily in filtration technology, but also in making sure the PURELINE DA29-00020B meets the exact designs and specifications as the original Samsung Original Water Filter. | PURELINE HISTORY: We were one of the first generic filters on the market. Our focus has and always will be on filtration technology and offering the highest quality filters on the market. | COMPATIBLE SAMSUNG FILTER MODELS: DA29-00020B, DA29-00020B-1, DA29-00020A, DA-97-08006A, HAF-CIN, HAF-CIN-EXP, HAF-CINEXP, HAFCIN, DA-97-08006A, DA-97-08006A-B, DA-97-08006B, DA29-00019A, DA29-00020A, DA29 00020B, DA2900019A, DA2900020A, DA2900020B, DA97-08006A-B, | COMPATIBLE SAMSUNG FILTER MODELS: DA29-00020B, DA29-00020B-1, DA29-00020A, DA-97-08006A, HAF-CIN, HAF-CIN-EXP, HAF-CINEXP, HAFCIN, DA-97-08006A, DA-97-08006A-B, DA-97-08006B, DA29-00019A, DA29-00020A, DA29 00020B, DA2900019A, DA2900020A, DA2900020B, DA97-08006A-B, | COMPATIBLE SAMSUNG REFRIGERATOR MODELS: RF22KREDBSR, RF23J9011SR, RF24FSEDBSR, RF263TEAESG, RF26J7500SR, RF28HFEDBBC, RF28HFEDBSR, RF28HMEDBSR, RS25H5111SR, RS261MDBP, RF28K9380SR, RS25J500dSR, RF23HCEDBSR, RF261BEAESR, RF263BEAESR, RF28JBEDBSG, RF4267HARS, RF4287HARS, and more listed below.
