20" Big Blue Carbon Block Filter - Last Stage of the whole house system

This is the final stage of both the 3 stage and the 4 stage whole house sysems.

It should be changed at least once a year.

If you start to smell chlorine in your water then you should change this filter and the GAC/KDF filter.

• Chemicals: Chlorine, chlorine byproducts (like THMs), and other disinfectants are removed to improve taste and odor.
• Organic compounds: It removes a wide range of volatile organic compounds (VOCs), pesticides, herbicides, and industrial solvents.
• Pharmaceuticals: Many modern filters are designed to reduce pharmaceuticals and other emerging contaminants from the water.
• Heavy metals: Some carbon block filters, especially those with additives like alumina, can remove heavy metals such as lead and copper.
• Taste and odor: The primary function is to remove unpleasant tastes and odors that may remain after other filtration stages.
• Sediment and turbidity: Carbon block filters are also effective at trapping sediment, dirt, rust particles, and fine particulate matter, depending on their micron rating
