Description
The 6 Inch Carbon Block Cartridge is a compact 5.0-micron filter made of compressed activated carbon. Its short length suits small housings, countertop filters, under-counter units with limited space, and appliances such as coffee machines and fridges. The dense carbon block reduces chlorine, taste and odour, and is specified for PFAS (per- and polyfluoroalkyl substances) reduction.
About PFAS
PFAS are a group of persistent man-made chemicals found in some water supplies worldwide. Carbon block filters with the right specification can reduce certain PFAS compounds. Performance depends on the specific cartridge certification, flow rate and water conditions, so we provide the manufacturer’s data sheet with the 6 Inch Carbon Block Cartridge. For complete removal of a wide range of contaminants, reverse osmosis remains the most thorough option.
