USTM BL 5" Active Carbon 4301973 is a 5-inch replaceable water filter cartridge made of a bonded activated carbon block. It is intended for use in household inline housings and other filter systems compatible with 5" cartridges, providing reduced chlorine, improved taste and odor, and lower levels of some heavy metals. The cartridge features a low dust profile compared with granular activated carbon cartridges and fits standard 5" x 2.5" housings. Service life is up to 8,000 litres or 6 months under typical conditions, with a maximum flow rate of 8 l/min.

Advantages

The bonded activated carbon block construction offers consistent adsorption performance, low particle release and compatibility with standard 5" filter housings. Effectively reduces free chlorine, organic contaminants and contributes to improved water colour, taste and smell. The cartridge is suitable for use in inline systems and as a replacement element in other compatible household filters.
