Water Sentinel (WSW-1) Whirlpool 4396508
Water Sentinel WSW-1 Whirlpool 4396508 Refrigerator Filter
The Water Sentinel WSW-1 is an economical alternative to OEM Whirlpool 4396508 filters, using carbon filtration to remove chlorine taste and odor while leaving beneficial minerals intact. Designed for easy installation and reliable performance over six months of typical household use.
Carbon Block Technology
The WSW-1 uses compressed carbon media to reduce chlorine, unpleasant tastes, and odors commonly found in municipal water supplies. Unlike RO or demineralization systems, this filter retains naturally occurring minerals like calcium and magnesium that contribute to water's flavor profile and potential health benefits. The carbon block provides consistent flow rates throughout its service life while maintaining reduction performance across the full 300-gallon capacity rating.
