H2O’s ULTRA+3™ advanced purification technology uses a 4 phase filtration system (with sixteen stages) similar to the Reboot Super-Phase™ in our waterREBORN system. It includes the same Remove Phase™ that removes suspended solids and large organics, and the same Reset Phase™ that reduces aesthetic, THM, small organic, and agricultural pollutant contaminants. The ULTRA Phase™ utilizes a larger pore membrane, that reduces monocellular, unicellular, infective agents, and carcinogens similar to the Restart Phase™ – but to a lesser degree. It also incorporates the same Rescrub+Polish Phase™ that ensures peak levels of deliciousness.
