The Brio 3-stage water filter replacement is compatible with Brio under-sink filtration models ROSL500 and ROSL500WHT. This 3-stage filter uses composite technology to integrate both polypropylene sediment and carbon fiber layers that together wrap around a central carbon block core. The result is a meticulous filtration process that reduces chlorine taste and odor, as well as other contaminants, ensuring drinking water is safe, clear, and great-tasting. And not only does it deliver a robust 2.5 liters per minute of refreshing hydration, but its easy twist-and-lock design lets you change filters in less than 10 seconds. You can count on the Brio multi-stage filter to provide reassuring filtration for 6 to 12 months.
