iSpring F3-NC 6-Month Prefilter Replacement Supply Filter Cartridge Pack Set for US31-NC F3-NC

Features

• Individually wrapped 6-month high capacity prefilter replacement cartridge pack for US31-NC under sink water filtration system
• This under-sink water filter uses catalytic carbon for exceptional filtration. Unlike standard carbon filters that remove 40-50% of chloramine, the FC15-NC filter can eliminate up to 99.4%. This high efficiency is due to the catalytic carbon's stronger ability to break down chloramine into harmless substances and absorb residual byproducts, ensuring safe, clean water.
• 3 pieces of 10" x 2. 5" replacement water filters included: 1x sediment filters, 1x granular activated carbon filters, and 1x carbon block filters.
• Note: Please unwrap the cartridges before use. Unlike an RO membrane, this filter retains healthy minerals in your water and does not reduce Total Dissolved Solids (TDS). For TDS removal, consider our iSpring Reverse Osmosis (RO) systems.
