About This

- 5 MICRON CARBON BLOCK FILTRATION – Designed to reduce chlorine taste and odor while capturing fine sediment, rust particles, dirt, and silt rated at 5 microns, supporting enhanced particulate control and consistent household water flow in treated municipal systems.
- CARBON BLOCK MEDIA DESIGN – Dense carbon block construction combines mechanical sediment filtration with adsorption technology, helping reduce chlorine while providing finer particulate reduction compared to higher micron carbon cartridges.
- IDEAL WHOLE HOUSE TREATMENT STAGE – Commonly installed at the main water entry point or as a dedicated carbon stage to help protect plumbing, fixtures, appliances, and downstream filtration equipment from chlorine exposure and fine sediment buildup.
- SERVICE LIFE VARIES BY WATER CONDITIONS – Replacement frequency depends on chlorine levels, sediment load, water quality, and household usage. Monitoring changes in taste, odor, pressure, or flow helps determine when cartridge replacement is needed to maintain system performance.
