Reverse osmosis works by pushing your water through a semi-permeable membrane under pressure. The membrane allows water molecules through while blocking dissolved solids, bacteria and other unwanted particles including microplastics and PFAS, so what comes out the other side is some of the purest drinking water available at home.
Unlike a standard carbon filter, which mainly improves taste and removes chlorine, RO filtration tackles a much wider range of contaminants. It’s the reason reverse osmosis is considered the gold standard for home drinking water filtration.
