NSF/ANSI 58 listed for TDS reduction: The iSpring RO500AK-BN is listed by NSF International to NSF/ANSI 58 for TDS (total dissolved solids) reduction. That listing covers TDS reduction only.* The contaminants or other substances removed or reduced by this water treatment device are not necessarily in your water.
Next-generation RO technology for faster, cleaner water: Building on the trusted RCC7 series legacy, the RO500AK-BN is iSpring’s tankless RO system. With a fast flow rate of up to 0.4 gallons per minute, it fills cups, pitchers, and cooking pots quickly — making it ideal for families, offices, coffee shops, restaurants, and more.
Superb three-stage filtration: The system's first stage combines a 2-in-1 Sediment and Carbon Block filter, followed by an advanced RO Membrane in the second stage. Certified to NSF/ANSI 58 for TDS reduction. The third stage uses a Carbon Alkaline Filter made with coconut shell activated carbon and minerals to polish the water, balance pH, and restore essential minerals for enhanced taste.
Economical and eco-friendly with a 2:1 pure-to-waste ratio: The RO500AK-BN's automatic membrane flush mode rinses the RO membrane for 20 seconds after 24 hours of non-use to extend its lifespan. The sleek, tankless design also frees up valuable under-sink storage space while adding a clean, modern look to your kitchen.
500 GPD output for high-demand households and businesses: Producing 500 gallons of filtered water per day, this system fills an 8 oz cup in just 10 seconds. Whether for a large family or a commercial setting, the RO500AK-BN delivers fast, stable water flow along with a detailed instruction manual for straightforward installation and maintenance.
Hassle-free installation and maintenance: The feed water adapter fits both ½" and ⅜" pipes, and the reinforced integrated water route design is designed for DIY installation. Filter replacements take only seconds and require no water supply shut-off. Covered by our 30-day return policy. Backed by iSpring's manufacturer warranty.
