NSF/ANSI 58 Certified – Complete System Certification: The iSpring RO500AK-BN is NSF/ANSI 58 certified for TDS reduction (scan QR code for the official NSF report). Its 0.0001 micron RO membrane removes up to 99% of contaminants including lead, PFAS, TDS, chromium, radium, fluoride, arsenic, chlorine, and more. Complete system certification ensures the entire RO unit—not just individual components—has been independently tested for performance and safety
Up to 0.4 GPM Real Flow (Fills 8 oz Cup in ~10 Seconds), 2:1 Low Drain Ratio, Auto Flush & Filter Reminder: iSpring RO500AK-BN reverse osmosis system provides up to 0.4 GPM (500 GPD)—fast enough for drinking, cooking, and filling pitchers. The 2:1 pure-to-waste ratio saves up to 400% water compared to traditional RO. Auto-flush after 24 hours of non-use protects the membrane. Front panel lights + buzzer alert you exactly when to change filters—no guessing
Alkaline Remineralization, Better Taste : iSpring RO500AK-BN features an alkaline remineralization filter that adds beneficial minerals back into RO filtered water and helps support a more balanced pH level. Compared to standard RO water, this alkaline filter is also designed to enhance the taste of the water, providing you with drinking water that is fresher, smoother, and more palatable

The quick-connect design supports 1/2” and 3/8” connections for fast DIY installation. Please note: This tankless RO system requires access to electricity
