Replacement Filter Cartridge Pack Set for Standard Reverse Osmosis RO Systems

The iSpring F3 premium quality 10" x 2.5" replacement pre-filter set is designed to extend the lifespan of your reverse osmosis membrane by utilizing the most innovative filtering technology. This pre-filter set consists of three stages, each with a specific function to ensure your water is clean, safe, and good-tasting.

The first stage of the pre-filter set is a high-quality multi-layer sediment filter that helps to reduce clogs and minimize pressure loss. This filter effectively traps larger particles and sediments, preparing the water for the subsequent stages.

In the second stage, the GAC (Granular Activated Carbon) loose carbon filter traps any remaining sediments in the water filtration process, ensuring that the third stage CTO (Chlorine, Taste, and Odor) filter does not become clogged easily. The GAC filter is made from high-quality coconut shell carbon and features 1.5 mm tiny pore carbon particles, providing maximum filtration efficiency and filter life.

The third stage of the pre-filter set is the CTO carbon block filter, which is made from bonded powered activated carbon filter media wrapped in a polyolefin pre-filter with a polyethylene outer netting. This filter effectively removes chlorine chemicals, as well as any lingering tastes and odors, ensuring that the water you drink is clean, safe, and good-tasting.

The iSpring F3 pre-filter set is designed to be a replacement cartridge pack for most standard RO (Reverse Osmosis) filtration systems. The pack includes three pieces of 10" x 2.5" replacement water filters: one sediment filter, one granular activated carbon filter, and one carbon block filter. This replacement pack does not include the RO membrane itself.

For those who may have trouble installing the filters, the manufacturer provides a user manual for guidance. Alternatively, users can contact the company directly for assistance.

By using the iSpring F3 premium quality pre-filter set, you can experience clean, safe, and good-tasting water every time you turn on the faucet. The innovative filtering technology and high-quality components ensure that your reverse osmosis system continues to function at its best, providing you with the peace of mind that comes with knowing your water is purified to the highest standards.
