iSpring RCC7AK-UV 7-Stage Alkaline & UV Under Sink Reverse Osmosis System

The iSpring RCC7AK-UV is a 7-stage under-sink reverse osmosis system built for people who want the complete package — the deep contaminant removal of RO, the better taste of remineralized water, and the added protection of UV sterilization, all in one NSF-certified system that installs under a standard kitchen sink.

NSF/ANSI 58 certified — the entire system.
This is a real distinction. The complete RCC7AK-UV system is certified to NSF/ANSI 58, not just an individual filter or material — a standard many competitors meet only at the component level. It's independently verified to reduce Asbestos (>99.7%), Barium (98.4%), Cadmium (98.8%), Chromium (99.2%), Copper (97.8%), Fluoride (97.4%), Lead (98.9%), Selenium (99.0%), and TDS (97.9%), and to cut up to 99% of over 1,000 contaminants including PFAS, chlorine, and arsenic. When the whole system carries the certification, the performance is proven, not promised.

Seven stages, each earning its place.
The foundation is the proven RCC7 reverse osmosis design — sediment pre-filtration followed by dual carbon stages (GAC and CTO, which together protect against chemicals better than carbon block alone), then the 75 GPD RO membrane that removes contaminants down to 0.0001 micron. From there, two stages set this system apart: an alkaline remineralization stage that restores healthy minerals and natural pH balance for a cleaner, more natural taste than standard 5-stage RO, and an 11-watt UV stage for a final layer of protection.

At 75 GPD (gallons per day), it comfortably handles the drinking water needs of a large family, and the included pressurized storage tank means treated water is always ready on demand.

The UV stage is what makes it well-water capable.
This is the feature that matters most for anyone off municipal water. The 11-watt UV lamp makes the RCC7AK-UV suitable for well water and other unreliable sources like lakes and streams, where microbial contamination is a genuine concern. A smart flow-sensor switch turns the UV unit on and off automatically with water flow — saving power and extending the life of the lamp. For rural properties, wells, and preparedness setups, that UV stage is the difference between "filtered" and "protected."

Built to install yourself and maintain for years.
The RCC7AK-UV is designed for DIY installation — push-to-connect fittings, color-coded tubing, and step-by-step video guides make it manageable for most homeowners, and everything needed for installation is included, along with a lead-free brushed-nickel faucet. The reinforced clear first-stage housing lets you visually inspect your sediment filter and see when it's time for a change before a problem starts. A fully mechanical Leak Stop valve automatically shuts off the water supply if it detects a leak — no batteries, no electronics. Standard-sized replacement filters keep long-term costs low.

Where the RCC7AK-UV fits in your water plan.
At Cana Provisions, clean water isn't just a field problem — it starts at home, and for anyone on a well or preparing for uncertain conditions, it's a serious one. The RCC7AK-UV is a complete home solution — RO, minerals, and UV in one permanently installed system. Our portable filtration, purification, and treatment gear handles you when you're away from it. Squared away at home. Field-ready when you leave. That's the whole picture.
