Polypropylene(PP) & Carbon(CF) Filter are both pre-stage filter prior to the use of RO filter. PP filter is an excellent polymer at removing large particles or sediments from public water infrastructure such as Dirt, Rust, Sand, etc. Many of the US states still uses lead🪨 service pipes which threatens community health. After PP filtering, CF filter contains activated carbon that absorbs chemicals such as Chlorine (cl), and Volatile Industrial Compounds🧪.

In Summary:

• PP deletes Dirt, Rust, Sand
• CF absorbs Chlorine
