The Can-Lite™has been developed with ease of installation, durability and effectiveness in mind and is manufactured the same way as the Original Can-Filter® (proven packed bed design) in a dedicated carbon filter plant in North America. The difference is in the carbon; special low density carbon is used in the Can-Lite™. 100% Australian Granulated carbon, aluminum top and bottom, integrated flange and well-made protective packaging are features of the Can-Lite™filter.
