Though RO water purifiers have become the preferred choice when it comes to removing harmful microbes from the water making it fit for drinking, the reverse osmosis process also removes minerals from the water, some of which are essential for good health. Unlike most RO water purifiers, Aquafresh Novo retains essential mineral nutrients while purifying water. The unit has a 10-stage purification system which includes filters, RO, UV, UF, and an anti scalant.
