The only cartridge in the range to target lead reduction. The CFB-PB10 reduces lead to World Health Organisation levels of 10ppb whilst providing all the other features of the Fibredyne range. The initial pressure drop is higher than other cartridges in the range so five micron pre-filtration is recommended. The CFB-PB10 is typically found in applications where there is lead piping in soft water areas or from borehole feeds.
