Compact Under-Sink Water Filter System for Contaminant Removal

Established in 2007 in Atlanta, Georgia, we have been dedicated to providing easily accessible clean water solutions to ensure that every household has access to safe water through our products. From the brand's inception, our mission has been to prioritize our customers by offering innovative products, easy DIY installation, and ongoing research and development of new filtration systems that set us apart from the competition. We take great pride in our commitment to excellence in designing and manufacturing quality water filtration products.

The CU-A4 Ultrafiltration Water System is designed to protect your home, health, and appliances by effectively removing the most problematic contaminants while maintaining a natural alkaline balance and great taste. This 4-stage filtration system utilizes advanced compound filters to reduce silt, rust, large particles, heavy metals, micron substances, matter, chlorine, and undesirable tastes and odors, resulting in clean, great-tasting water for direct drinking, coffee, or other beverages, all while retaining natural minerals.

Simplicity and convenience are key features of the CU-A4. The push-to-connect fittings and color-coded tubing make the installation process straightforward, and the iSpring Twist On/Twist Off filter cartridges simplify the filter-changing process. A drinking faucet is also included in the package, providing a complete solution.

What sets the CU-A4 apart is the inclusion of Kinetic Degradation Fluxion (KDF) Media, an additional layer of protection that helps control heavy metals. The Ultra Filtration (UF) stage utilizes hollow fiber membrane technology with a pore size of just 0.01 micron, surpassing the performance of both carbon block and 'portable mini' water filters.

As America's favorite brand of water filtration systems, iSpring rigorously tests all of our products for air leaks, pressure, and cycle resistance to ensure years of trouble-free, low-maintenance performance. The CU-A4 Ultrafiltration Water Filter System is designed to reduce major contaminants from your water supply while maintaining a natural alkaline balance and great taste, providing clean water for drinking, showering, cooking, and other household uses.

Unlike Reverse Osmosis (RO) systems, the CU-A4 does not lower TDS (Total Dissolved Solids), but instead keeps the beneficial minerals in your water. The push-to-connect fittings and colorful coordinated tubing simplify the installation process and prevent leaking, while the slim and compact design allows for easy under-sink mounting, leaving you more storage space.

In addition to the convenience and space-saving benefits, the CU-A4 offers a cost-effective and sustainable solution for enjoying clean, filtered water in your home. By eliminating the need for expensive bottled water and water delivery services, you can save a significant amount of money over time.
