iSpring RCC7AK-UV 7-Stage Under-Sink RO with Alkaline Remineralization and UV — NSF Certified

Meet the iSpring RCC7AK-UV, a 7-stage under-sink reverse osmosis system designed to deliver purified drinking water with a balanced mineral note. Built around RO technology, this unit tackles a broad spectrum of contaminants while adding minerals for taste and pH balance. The system harmonizes filtration, remineralization, and UV disinfection in one compact package, making it a practical upgrade for households seeking consistently fresh-tasting water from their kitchen tap.

At its core is a 75 GPD RO membrane paired with a mineral AK stage that gently reintroduces essential minerals to create water with a natural balance. The 11W Philips UV lamp provides an extra layer of disinfection, activated only when water flows through the unit thanks to a smart flow sensor. This design helps conserve energy and extend lamp life, while delivering peace of mind for daily use.

What makes RCC7AK-UV stand out

• NSF/ANSI 58 certification covers the entire system, not just individual components, for robust performance.
• Extended filtration includes 7 stages: sediment, GAC, CTO, high-rejection RO membrane, inline carbon, alkaline remineralization, and UV.
• The mineral AK stage adds a balanced mineral blend, contributing to a smoother, more natural-tasting final water.
• A transparent first-stage housing allows quick visual checks without disassembly, helping you monitor filter status at a glance.
• Top-mounted faucet design and DIY-friendly installation keep setup simple, with compatibility across a wide pH and pressure range.
• UV filtration adds an extra layer of protection during daily use, with the lamp turning on only when water flows.
• Clear replacement filter schedules (6–12–24 month cycles) help simplify maintenance and planning for families.

In daily use

• Enjoy crisper, cleaner-tasting water from the dedicated kitchen faucet, suitable for drinking, cooking, and coffee.
• Natural mineral remineralization supports a balanced mouthfeel and avoids overly flat water sensation.
• UV filtration adds reassurance for households seeking an extra safeguard against microbes without extra steps.
• Minimal maintenance with accessible filter changes and a service team ready to help if needed.

Installation and notes

The RCC7AK-UV is designed for easy DIY installation and works with city or well water in a typical home setting. It does not include a booster pump, so if your water pressure dips below 45 PSI, consider the RCC1UP-AK model as an alternative. The system handles a broad water temperature and pressure range and can be integrated into most under-sink setups with standard fittings. A small note: water coming out of the UV stage may feel slightly warm for the first few seconds as water moves through the lamp housing.

With this configuration, you’ll benefit from a compact, durable filtration solution backed by iSpring’s support network and replacement filter options to keep your system performing at its best year after year.
