Tired of slow reverse osmosis systems, wasted under-sink space, or concerns about what’s really in your drinking water? The iSpring RO500AK-BN Tankless Reverse Osmosis Filtration System delivers advanced under sink reverse osmosis filtration with ultra-fast water flow, powerful contaminant reduction, and alkaline remineralization in one sleek, space-saving design.
NSF 58 Certified for TDS reduction, the RO500AK-BN is engineered to provide trusted whole-system filtration performance for cleaner, safer, better-tasting water at home, in offices, coffee stations, and high-demand kitchens.
Its advanced multi-stage reverse osmosis filtration system helps reduce up to 99% of over 1,000 contaminants, including lead, chlorine, fluoride, arsenic, asbestos, sodium, calcium, and other unwanted impurities that can affect water quality, taste, and safety. The built-in alkaline remineralization stage helps restore beneficial minerals and balance pH levels for cleaner, crisper, more refreshing water.
Designed for modern households, this 500 GPD tankless reverse osmosis system delivers purified water at up to 0.4 gallons per minute, filling glasses, reusable bottles, pitchers, and cooking pots significantly faster than traditional RO systems.
Its efficient 2:1 pure-to-drain ratio helps reduce wastewater compared to conventional reverse osmosis systems, while the sleek tankless under-sink design frees up valuable cabinet space and reduces clutter. An intelligent automatic membrane self-cleaning system helps extend filter life and maintain long-term filtration performance with minimal maintenance.
Installation and upkeep are designed to be simple with a leak-resistant integrated water route system and quick-change filter design that allows tool-free filter replacement in seconds.
