Simpler and more compact than Reverse Osmosis systems, the CU-A4 is an excellent choice for most general water filtration applications. The advanced 4-stage design of the CU-A4, featuring a unique combination of Activated Carbon, Ultra Filtration and KDF filters, eliminating a wide variety of contaminants, including lead, arsenic, iron, nickel, chromium, cadmium, calcium, aluminum, mercury, chlorine and chlorine treatment by-products, hydrogen sulfide and more. Experience clean and better-tasting water without the hassle, expense and negative environmental impact of bottled water. The CU-A4 is flexible, quiet, and durable. It has no moving parts and is very easy to maintain – only requiring occasional filter replacement. iSpring’s high-capacity, high-performance filters last up to twice as long as other filters and provide great water flow – a difference you’ll notice when you turn on the faucet. The “Twist on / Twist off” filter design means changing filters couldn’t be easier. A lead-free faucet with beautiful chrome finish, included with the system, is usually mounted on the counter as the primary source of drinking water, but with a wide range of optional parts and accessories, the CU-A4 easily adapts to fit nearly any refrigerator or ice maker connection. Contact iSpring directly and speak with a product specialist to make sure you get the right filter options for your needs. We know that many customers prefer do-it-yourself installation, so the CU-A4 has been designed from the ground up to be easy for most users to install themselves, using readily available tools. Our push-to-connect fittings simplify the installation process and minimize the possibility of leaks. A well-organized instruction manual guides you step-by-step through the entire installation and testing process. If you do run into an issue, or get stuck, our technical support team is ready to assist you, Monday thru Friday between the hours of 9am to 5pm Eastern time. The whole system is backed by a 1-month money-back , a 1-year manufacturer and iSpring’s unique lifetime technical support provided right here in the USA in Atlanta, Georgia. If you have a need to reduce overall dissolved solids in the water (reduce TDS) or to remove heavy concentrations of metals like lead or copper, then an Reverse Osmosis system like the spring RCC7 is recommended. But for all-around high-performance water filtration, or where space is at a premium, the CU-A4 is the best, most economical and flexible choice for clean, fresh, great-tasting water instantly. NOTE: If you plan to use the CU-A4 as an inline filter (meaning using it without the included air-gap faucet), your incoming water pressure needs to be 40 PSI or below. If it is above that, a 40 PSI pressure regulator (APR40) should be installed on the input line to keep the pressure on the system at 40 PSI or below. Please contact us if you plan to “tee off” the pure water line and connect it to your fridge, as you would need a regular RO faucet along with a pressure regulator.
