iSpring F9K NSF Certified 1-Year Replacement Pack

Designed for six-stage reverse osmosis systems, the F9K replacement pack makes annual maintenance straightforward. The nine filters are individually wrapped, helping you keep track of parts and ensuring you have fresh replacements ready for a full year of filtration.

What’s included

Individually wrapped filtration components support storage and handling between replacements, so you can swap with confidence when the time comes.

Fit and compatibility

The cartridge set is sized for standard housings that use 10 inch by 2.5 inch cartridges. A push-fit quick connection is designed to speed up changes, reducing downtime for everyday use in busy homes.

Alkaline remineralization

The two alkaline filters reintroduce minerals such as calcium, magnesium, and potassium, contributing to a balanced taste profile and a smoother feel on the tongue. The remineralization step complements RO filtration without claiming health outcomes.

Everyday benefits you might notice

• Clearer taste in water, tea, and coffee with consistent pour quality
• Better tasting ice and more enjoyable beverages for the family
• More predictable maintenance planning across the year
• Foods and sauces experience a fuller flavor when using filtered water

This pack does not include an RO membrane. The updated alkaline mineral filters and post-carbon filters use a secure push-fit connection for faster swaps. For assistance, consult the user manual or contact support if you run into fit or install questions.
