CF group has added a new series of canister filters to their already dominant line of activated carbon filters. After years of research and field testing of the light-weight carbon filter, CF group will proudly place their trusted name in air filtration on this new series of filters. The Can-Lite 100 has been developed with ease of installation, durability and effectiveness in mind. The Can-Lite is manufactured the same way as the Original Can-Filters. These filters use 10% more virgin activated Australian RC light weight granular carbon. The bed depth is 2 in. Up to 2.5 years of life expectancy. All filters include a low resistance pre-filter. Each filter is shrink wrapped, boxed and labeled for ease of use.
