Triple Defense: SimPure DB20P-3KDF 3 Stage Whole House KDF Water Filtration System
1. The first stage is a PP sediment water filter. This water filter is specially designed to remove up to 99%+ of sediment, dust, sand, large particles, silt, dirt, and rust that can clog the filters that follow.
2. The second stage is a KDF (Kinetic Degradation Fluxion) filter, known for its powerful adsorption capacity. It helps effectively reduce heavy metals such as lead, arsenic, manganese, and iron, while also minimizing chlorine and controlling scale. The KDF 55 media helps inhibit bacterial and algae growth within the system, keeping the filtration environment clean and extending the life of downstream filters.
3. The third stage is a CTO (chlorine, taste, and odor) carbon block filter that effectively reduces up to 99% of chlorine, pesticides, herbicides, industrial chemicals, and unpleasant tastes or odors. It helps deliver cleaner, better-tasting water that’s safe and enjoyable for the whole family.
