iSpring F9K 1-Year RO Replacement Filter Set: Overview

The iSpring F9K is a 1-year replacement filter set for 6-stage reverse osmosis systems. It packs 9 individually wrapped cartridges in the standard 10″ x 2.5″ size.

• A full year in one box: You get 2 sediment filters, 2 granular activated carbon filters, 2 carbon block filters, 2 alkaline filters, and 1 post-carbon filter. So you can change filters on schedule without reordering. Please note the pack does not include an RO membrane.
• Effective contaminant removal: Each filter is designed to target specific contaminants. Working together, they provide clean, safe drinking water for your household. 
• Comprehensive Pre-Filtration: Sediment, granular activated carbon, and carbon block filters help capture larger particles, remove unpleasant tastes and odors, and reduce chlorine, VOCs, and other contaminants that could damage the RO membrane. 
• Minerals added back: The alkaline filter adds beneficial minerals such as calcium and magnesium back into the filtered water. As a result, it helps balance the pH of filtered water and improve its taste. 
• Cleaner taste: The post-carbon filter removes leftover odor and taste, so coffee, tea, and ice taste fresher.
• Faster swaps: The updated alkaline and post-carbon filters feature secure push-fit connections for quick filter cartridge replacement. 

If your 6-stage system needs fresh filters, the iSpring F9K covers a full year of changes in one order.
