CTO Series Extruded Carbon Block Cartridge Filters


CTO Series Extruded Carbon Block Cartridge Filters are made of activated carbon block which is manufactured according to  strictly extruded & controlled engineering processes.Advanced techniques and FDA approved material of the high-quality activated carbon guarantee excellent durability, minimal pressure loss and high flow rate. Carbon block cartridges are highly effective in removing odour, bad taste, chlorine spores and microorganisms in water. Carbon block cartridge filters provide economical solution for a wide range of residential, commercial and industrial water filtration processing.
