When it comes to the water we use and consume in our homes or in our small businesses, prioritizing clean, mineral-rich water is a must. Our RO500AK-BN is our next-generation reverse osmosis filtration system that raises the bar for water purification and provides the perfect blend of innovation, efficiency, and eco-friendliness to meet your water needs while removing up to 99% of over 1,000 water impurities including PFAS, lead (up to 98% removal), chlorine, fluoride, arsenic, asbestos, calcium, sodium, and more.

This three-stage system ensures you get the best of both worlds: purity and great taste. It’s equally perfect for those who are health-conscious as well as those who are eco-conscious, offering a filtration system that provides clean, mineralized water while reducing water waste.
Features that Make a Difference
There are many RO systems on the market, but three key features set our RO500AK-BN apart: its production capacity, exceptional pure water-to-wastewater ratio, and remineralization stage.

- Balanced pH and Remineralization
Unlike many other reverse osmosis systems that strip minerals from your water, our RO500AK-BN employs a third-stage carbon alkaline filter that restores essential minerals like calcium and magnesium, providing you with healthier, tastier water. - High Capacity
This filtration system is engineered to provide up to 500 gallons of purified water per day with a fast flow rate of nearly half a gallon per minute, making it perfect for daily use by families and small offices. Whether you’re drinking, cooking, or preparing beverages, this system ensures you have a steady supply of clean water. - Water-Saving Design
This system has an industry-leading 2:1 pure-to-drain ratio, which reduces water waste by up to 400% when compared to traditional RO systems, making it an eco-friendly choice. The efficient design not only saves you money on your water bill but also helps conserve water without compromising on performance, making it perfect for those who want to reduce their environmental footprint.
