## Description

This under-sink reverse osmosis system brings alkaline remineralization and a stylish black faucet to a home kitchen, offering bottled-quality water while restoring natural pH and adding essential minerals for better taste. It is a six-stage unit that combines thorough contaminant reduction with a modern appearance, suitable for daily drinking and cooking use.

## Key Points

The system reduces up to 99% of over 1,000 contaminants according to the manufacturer, including lead, fluoride, chlorine, PFAS, and asbestos, while the remineralization stage returns healthy minerals and raises pH for a cleaner flavor. The included sleek black RO faucet adds a contemporary touch to the sink area and matches modern kitchen finishes. Installation is designed to be DIY-friendly with quick-fitting connectors and a clear manual, and the first-stage transparent housing makes routine visual checks straightforward.

## Technical Specifications

- Name: **iSpring RCC7AK-BLK**
- Stages: - 6-stage reverse osmosis filtration
- Membrane pore size: - 0.0001 microns (RO membrane)
- Certifications: - NSF/ANSI 58 certified for system performance
- Contaminant reduction examples: - Lead 98.9% according to the manufacturer, fluoride 97.4% according to the manufacturer, TDS reduction 97.9% according to the manufacturer

## Benefits

The extra alkaline stage is intended to improve water taste by reintroducing minerals and balancing pH, which many users notice compared to standard five-stage RO units. Low-maintenance elements include three pre-filters that protect the membrane and a fine GAC filter that polishes water before remineralization. The transparent sediment housing helps catch early signs of clogging without removing the whole assembly, saving time during simple checks.

## Usage Recommendations

Measure available under-sink space before installation to ensure a comfortable fit, especially if plumbing or storage is tight. Replace pre-filters, RO membrane, and post-filters according to the manufacturer’s schedule to maintain performance, and consider periodic testing of output water if you need to verify specific contaminant levels. Note that while the system removes a wide range of impurities, according to the manufacturer some reduction rates vary by contaminant and source water quality.
