iSpring US31 Classic Under Sink Water Filter, Tankless, High Capacity, Replacement Cartridge Pack Set

Classic Drinking Filter: Pure, Healthy Water Straight from Your Tap

Unique Filtration System The Classic Drinking Filter features a triple filtration process: PP sediment filtration, dual carbon filtration, and a unique second layer of CTO carbon filtration. This system removes sediments like dust, sand, particles, dirt, and rust, while effectively eliminating heavy metals, harmful chemicals, cloudiness, and colors. It also noticeably improves the taste and odor of your water, making it cleaner and more refreshing.

On-Demand, High-Flow Performance With up to 20 times the effectiveness of a common water pitcher dispenser, the iSpring US31 delivers fast-flowing water. Its demand-based flow rate allows for up to 1 GPM (gallon per minute) depending on your water pressure, up to a maxim of 90 psi. Use it to wash fresh produce, bring health benefits to your family, and enjoy clean and delicious water directly from your tap.

High-Quality Design and Manufacturing Crafted with a beautiful European-designed brushed nickel all-metal faucet and a see-through 1st stage housing, this filter is not only functional but also aesthetically pleasing. The clear 1st stage housing makes it easy to inspect the filter. The system is strictly manufactured to comply with FDA standards and tested by independent third-party labs against NSF/ANSI standards (42, 53, 61) for water quality, material safety, and structural integrity.

Easy Installation and Maintenance This system is designed for effortless installation and low maintenance. It includes dual carbon block filters and a high-capacity sediment filter. The sediment filter protects and extends the life of your system, while the carbon block filters tackle numerous harmful contaminants. Replace the filter every 6 to 12 months based on the water’s taste to ensure optimal performance.
