About This

  • Advanced Water Filtration Technology: Our whole house water filter pack incorporates three specialized filters for comprehensive water purification. The first-stage polypropylene sediment filter (FP25B) captures particles as small as 5 microns. The second-stage FG25B-KS compound filter is tailored to eliminate a wide range of contaminants, including chlorine, chloramine, lead, mercury, hydrogen sulfide, heavy metals, PFAS, herbicides, and odors.
  • The third-stage iron water filter (FM25B) is designed to specifically address iron and manganese, effectively reducing iron levels (up to 3.0 ppm) and manganese (up to 1.0 ppm).
  • Fits Standard Housings: Designed to fit seamlessly into standard housings that accommodate 20” x 4.5” whole house water filter cartridges, including popular brand-name models.
  • Exceptional Performance and Longevity: These replacement cartridges ensure minimal impact on water flow, providing a flow rate of up to 15 GPM while requiring minimal maintenance. Depending on your water quality and usage, the filters are designed to supply a family of four with clean water for up to an entire year.
  • Dedicated Customer Service: Experience peace of mind with our top-notch customer support. We offer technical assistance and customer service via phone or email, directly from our headquarters in Atlanta, GA. Our knowledgeable team is committed to helping you find the ideal filtration solution for your specific water concerns and assisting with any post-purchase support you may require. Our goal is to enhance your overall user experience.
  • Important Note: Unlike reverse osmosis (RO) membranes, these filters do NOT reduce Total Dissolved Solids (TDS). Instead, it preserves essential minerals in your water while effectively removing harmful chemicals. If your focus is on TDS reduction, we recommend exploring our iSpring Reverse Osmosis (RO) systems. Each filter cartridge is individually wrapped to maintain freshness; please ensure you unwrap the cartridges before installation.
