The Swift Green Filter’s SGF-W41 refrigerator water filter is a compatible Whirlpool 8171414 replacement that provides fresh, clean, and great-tasting drinking water. This filter reduces – chlorine taste odor (CTO), volatile organic compounds (VOC), cyst, sediment and lead. Our filters are made with activated carbon that is produced by using a new technology that carbonizes dried coconut shells. The coconut carbon created by this technology provides 50% more micro-pores for capturing contaminants. For more information, please visit the Swift Green Filters website.
