The iSpring RO500AK-BN is a tankless reverse osmosis system that filters up to 500 gallons a day and adds alkaline minerals back into your water.

• Three-stage filtration: A sediment and carbon block filter, an RO membrane, and a carbon alkaline filter remove up to 99% of over 1,000 contaminants, including lead, chlorine, fluoride, and arsenic.
• Low water waste: Its 2:1 pure-to-drain ratio sends up to 400% less water down the drain than a standard RO system, which saves water and money.
• No tank needed: The tankless design frees up under-sink space and delivers a fast flow of up to 0.4 gallons per minute, filling an 8-ounce cup in about 10 seconds.
• Alkaline remineralization: The carbon alkaline filter raises pH above 8 and adds minerals back in, so the water tastes better instead of flat.

NSF/ANSI 58 certified and backed by a 1-year warranty, the RO500AK-BN delivers clean water without the bulk of a tank.
