Refined and iSpring US31 Classic 3-Stage Under Sink Water Filtration System

Revised Content:

This 3-stage filter system is designed for easy installation and low maintenance, featuring dual carbon block filters along with a high-capacity sediment filter. The sediment filter protects and extends the life of the system, while the carbon block filters work to remove many harmful contaminants, providing you with bottled quality water on demand.

The water undergoes a three-stage purification process: PP sediment filtration, GAC carbon filter, and a unique CTO filtration in the third layer. This system efficiently removes common drinking water sediments such as dust, sand, particles, dirt, and rust. Additionally, it effectively eliminates heavy metals, harmful chemicals, Chloramine, cloudiness, colors, chlorine taste, and odor. It's important to note that this under-sink water filtration system does not lower the TDS (Total Dissolved Solids) value but preserves the healthy minerals in your water, allowing you to enjoy pure, great-tasting water with essential minerals intact.

The on-demand fast flow rate of the iSpring US31 allows it to meet a wide range of needs in your home, being up to 20 times more effective than a common water pitcher dispenser. The flow rate can reach up to 1 GPM (Gallons per Minute), depending on the source water pressure, with a maximum pressure of 90 psi. This system can be used to wash fresh produce like fruit and vegetables, providing health protection and delivering delicious, clean water straight from your tap to your entire family.

The system features a beautiful European-designed brushed nickel all-metal faucet and a clear see-through first-stage housing, making filter inspection a snap. Manufactured to comply strictly with FDA standards and tested by independent third-party organizations against NSF/ANSI standards (42, 53, 61) for water quality, material safety, and structural integrity, you can trust the excellent quality and design of this product.

Designed for easy installation and low maintenance, this system features dual carbon block filters and a high-capacity sediment filter. The sediment filter protects and extends the life of the system, while the carbon block filters work to remove many harmful contaminants. You can replace the filters every 6 to 12 months, judged by the water's taste.

Please note that this under-sink water filter will not reduce the TDS of the incoming water, but instead, it keeps the healthy minerals in your water. If you are interested in a filter that removes TDS, please consider an iSpring reverse osmosis system.
