Can Carbon Filters – Can-Lite Range Released after years of testing and research, the Can-Lite has been developed with ease of installation, durability and effectiveness in mind. The Can-Lite is manufactured using a similar process to the Can-Original Filters but instead using a highly perforated, light aluminum casing and a special grade of virgin CKV-4 carbon. This allows the filters to be lighter and handle larger air flow rates without any odor breakthrough. Features: Light weight Can handle relatively high (fan) flow rates Flanges are pre-fitted to the filter Packaged in their own individual carton Pre-filter included
