Want to make sure that your water is clean, healthy, and tasting great? Perfect, because thatís exactly what the DA29-00020B filter does. The filter takes your municipal or well water and passes it through activated carbon, which traps many of the contaminants found in tap water. The clean water is then passed on to either be drank or made into ice. We offer three different DA29-00020B models: the OEM Samsung replacement, the aftermarket Supco replacement, and the aftermarket Swift Green replacement, which is made from an eco-friendly process. Each filter model has a filtering capacity of 300 gallons and has a water flow rate of a half gallon per minute. Installing these filters is extremely easy, and we suggest that the filters be changed at least once every six months to ensure that your water remains as healthy and clean as you want it to be.
