Designed to be compact, the NU Aqua 600GPD Tankless Reverse Osmosis Systems features four stages of premium water filtration while being 25% smaller than traditional style water filtration systems. Let’s face it, most water filters take up a lot of space under your sink and the ones that don’t are not effective. Which is why we designed this system to keep the same filtration standards high and the system size small. 1. The PP/CB Filter lasts around 6 months and offers you two stages of filtration that removes suspended particles like sediment and rust, as wells as chlorine, volatile organic polluants (VOC's), taste and odor. 2. The Granular Activated Carbon (GAC) filter lasts around 12 months and helps absorb organic chemicals, odors, and improves taste. 3. The 600GPD RO membrane lasts around 36 months and helps get rid of heavy metals like copper, chromium, lead, fluoride, nitrate, and salts. What makes the NU Aqua 600GPD Tankless system different?
