Features & Details
The CP Workhorse Plus is a premium, high-capacity carbon block filter. Measuring 4.5" × 10", it is a standard "Big Blue" size cartridge built to fit most universal heavy-duty 10-inch whole-house water filtration systems.
This carbon block cartridge helps improve the taste, odour, and appearance of water by reducing chlorine and other chemicals.
Ideal for residential, cottage, light commercial, and pre-treatment applications, this filter is commonly used where a larger 4.5" diameter cartridge is required for better flow and longer filter life compared to standard slimline cartridges.
