Braukmann Triplex Water Filter FF60. Bought new and never ended up installing it. Still like new and in original packaging. The Resideo Braukmann FF60 is a rainwater filter designed to filter out dirt and sediment from rainwater before it is used for irrigation, flushing toilets, and other non-potable uses. It combines a filter of 100μm, a fine filter of 25 microns, and an active carbon filter to provide effective filtration. This filter is part of the Resideo Braukmann Triplex rainwater filter series, which is designed to provide reliable and efficient water filtration solutions.
