The Critical Specs


Superb Filtration Performance

The FG15B-KS 10” x 4.5” compound filter is designed to effectively remove a wide range of contaminants and impurities from your water. It efficiently removes chlorine, lead, mercury, hydrogen sulfide, iron, chloride, chloramines, herbicides, odors, and more. Our filter ensures that your water is free from harmful toxins.

Water Health Warrior

Partnering with carbon filters like iSpring FC15B, the FG15B-KS filter is incredibly powerful in removing the unpleasant taste or odor often found in chlorinated water. It maintains the protective benefits of chlorine in water disinfection while addressing issues like turbidity, cloudiness, bad taste, and odors, such as hydrogen sulfide, which can smell like rotten eggs. A reliable shield that protects you and your family from ingesting harmful chemicals or contaminants in your tap water.

Great Compatibility

This filter is the official 1st stage replacement cartridge for iSpring’s direct connect Point-of-Use (POU) undersink water filtration system US21B. It fits standard 10" undercounter or whole house water filtration systems. Each filter is individually sealed for freshness and optimal performance.

Exceptional Filter Life

Based on the contaminant levels in your source water and your water usage, we recommend changing the filter every 8-12 months for optimal filtration performance. Filter replacement is hassle-free and easy.

TDS Note

Please note that this system is not designed to reduce Total Dissolved Solids (TDS) and retains essential minerals in your water. If you are interested in a filter that significantly reduces TDS, consider our iSpring Reverse Osmosis (RO) systems RCC7 series or tankless RO500.

Peace-of-Mind Support

We provide tech and customer support via phone and email from our offices in Atlanta, GA. Our responsive and professional team is here to help you select a product that meets your water filtration needs and to support you after the sale to maximize your user experience. Now and years to come, we will be right here and ready to help.
