Waterdrop Whole House Filter CTO Carbon & Grooved PP Cartridge 10x4.5 in — Reduces Chlorine, Taste & Odor | 5 Micron

Overview

Transform the water you use every day with the Waterdrop Whole House Filter. Designed for 10" x 4.5" systems, this cartridge pair leverages a CTO carbon filter together with a grooved polypropylene (PP) pre-filter to deliver cleaner water across your home. It’s built for straightforward replacement and broad compatibility, so you can upgrade without major plumbing changes.

How the filtration works

• CTO carbon and grooved PP work in tandem to target dirt, silt, rust, and other large particles, while dramatically reducing chlorine and the associated taste and odor.
• The grooved PP filter offers a larger filtration area, supporting stronger performance and longer life for steady, everyday filtration.
• The system is built to operate at the 5 micron level, helping to capture finer impurities as water travels through your home.

Performance and lifespan

• With up to 50,000 gallons of filtration capacity, expect a typical replacement schedule of 3–6 months for the PP filter and up to 6 months for the CTO carbon filter, depending on usage and water quality.
• The grooved PP filter features a 2.2× larger filtration area for enhanced performance over time.
• By reducing sediments and impurities, the filter can help minimize buildup in water heaters, washing machines, and dishwashers.
