• Advanced 1st Stage Filter (FG15B-KS): The 10” x 4.5” compound filter is designed to remove a wide range of contaminants, including chlorine, lead, mercury, hydrogen sulfide, THMs, chloramines, herbicides, odors, and other impurities. Made with high-quality coconut shell carbon and advanced fabrication technology, it ensures superior filtration performance.
• Highly Effective 2nd Stage Filter (FC15B): The 10” x 4.5” CTO carbon block filter knocks out cloudiness, bad tastes, and odors, while effectively removing up to 99% of chlorine. It is also highly efficient in eliminating herbicides and industrial solvents.
• Individually Sealed for Freshness: Each filter is individually sealed to maintain maximum freshness and ensure top-notch performance. Replace the filters every 8-12 months, depending on the source water quality, to achieve optimal filtration results. For easy filter change tips, refer to our manual and helpful YouTube videos.
• Preserve Essential Minerals: Please note that this filter pack is NOT designed to reduce Total Dissolved Solids (TDS). It allows essential minerals to remain in your water, promoting better taste and overall well-being. If you prefer a filter that removes TDS, consider exploring our iSpring Reverse Osmosis (RO) systems like RO500, RCC7, RO100, and more.
