WÜDR products
Reverse osmosis
Three drinking-water systems for the kitchen sink: the WÜDR Tankless RO 800 and 600 (tankless) and the Puronics Pur-Alkaline PC6-38-B (with storage tank).
Choosing the right one
Choose tankless for on-demand flow and a smaller footprint (both need an outlet), or the Pur-Alkaline for a tank system that needs no power. Compare Tankless RO 800 vs. 600 or tankless vs. tank RO, and read how RO works.
