Cartridge filters are installed where water free of suspended substances such as sand, limestone scales and iron oxide is required. Once detached from the pipes, these substances damage or obstruct taps, shower heads and wall boilers. The ½’‘ JOLLY filter, with a compact and attractive design and a practical team attachment, can be equipped with CL2 washable cartridges to be discarded in CCA2 wire-wrapped polypropylene, CC2 carbon and CX2 stainless steel.
