Under Sink Reverse Osmosis Water Filtration System for Multi-Stage Purification

Advanced Multi-Stage Filtration for Every Need – Engineered for superior performance, the iSpring Reverse Osmosis System removes up to 99% of over 1,000 contaminants including PFAS, chlorine, fluoride, lead, arsenic, asbestos, and calcium. With models ranging from 5-stage to 7-stage systems (including Alkaline and UV options), you can choose the ideal balance of purity, taste, and protection for your home or office.

High-Performance 200 GPD Membrane – Select models feature a powerful 200 gallons-per-day RO membrane that delivers fast, reliable water flow to meet the demands of large households, offices, or small commercial spaces. The optimized 3:1 pure-to-drain ratio minimizes water waste while maximizing clean water output.

Alkaline Remineralization & UV Protection – Optional alkaline stages restore beneficial minerals like calcium and magnesium for balanced pH and great-tasting, mineral-rich water. UV-enhanced systems add an extra layer of protection, neutralizing microorganisms and ensuring microbiologically safe drinking water for every pour.

Certified Quality & Durable Design – Certified to NSF/ANSI 58 standards, every iSpring system is built with premium components for long-lasting, leak-free operation. The transparent first-stage housing lets you see filter buildup at a glance, while the check valve prevents backflow. The designer lead-free faucet (available in Brushed Nickel or Sleek Black) adds elegance to any kitchen setup.

Effortless DIY Installation & Low Maintenance – The patented top-mounted faucet fastener allows installation entirely from above the counter, eliminating the need to reach underneath the sink. With quick-connect fittings, color-coded tubing, and detailed step-by-step guides, setup is simple and tool-friendly.

What Customers Say – Users praise the crisp, refreshing water taste, improved clarity, and easy installation. Many note that coffee, tea, and baby formula taste noticeably better, and the water’s purity rivals or exceeds bottled water. Homeowners appreciate the reliable U.S.-based support and long-term performance.
