The PRISM Max grade carbon block is specifically formulated for effective chloramine control and the only cartridge to offer this feature within the range. Having been manufactured within a five-stage process, this exceptional catalytic activated carbon cartridge offers up to 10 times the capacity of the Plus grade. Essential for use in public water supplies where chloramine has been added as the disinfecting agent of choice, the Max grade carbon block will typically be found within applications including aquatics and renal dialysis. Rated at one micron, pre-filtration from the PRISM spun range, such as the Plus grade DSPP at five micron, is recommended to maximise service life and prevent premature blocking.
