GAC cartridge is our most popular cartridge, the flow of water from bottom

contact time allowing for maximum adsorption and treatment. Using a clean,
acid washed bituminous carbon with a large
mesh size. This granular range is primarily a chlorine, taste and odour
reduction cartridge with the advantage of a course
20 micron pre and post filter to retain carbon fines that is not
susceptible to blockage if high particulate is present.
