iSpring 9-Piece Polypropylene and Granular Activated Carbon Water Filter Replacement for Under-Sink

The F9K 1-year filter pack comes with a total of 9 replacement filters, allowing for scheduled filter changes over the course of a year. Included in the pack are:

2x 5 Micron 10" Sediment Filters (1st Stage, #FP15): Removing dirt, rust, sand, and other particles, to be replaced approximately every 6 months. 2x 5 Micron 10" Granular Activated Carbon (GAC) Filters (2nd Stage, #FG15): Absorbing chlorine, halide, organic contaminants, odors, and other impurities that contribute to bad tastes and odors, to be replaced approximately every 6 months. 2x 5 Micron 10" CTO Carbon Block Filters (3rd Stage, #FC15): Further removing any remaining chlorine, tastes, and odors, to be replaced approximately every 6 months. 1x Post Carbon Inline Filter (5th Stage, #FT15): Polishing the water from the tank before it is delivered to the faucet, to be replaced approximately every 12 months. 2x Alkaline pH Remineralization Filters (6th Stage, #FA15): Adding 0.5 - 0.8 pH back to the water, as well as healthy minerals such as ionized calcium, magnesium, sodium, and potassium which were removed during the RO process, to be replaced approximately every 6 months.

The 1-year filter supply does not come with an RO membrane, as the membrane only needs to be changed every 2-3 years. For a filter pack that includes the membrane, the 2-year F19K75 or 3-year F28K75 supply pack can be considered.

This filter pack is compatible with the iSpring RCC7AK, RCC7P-AK, and most other RO systems that use standard sized filter housings, including Flowmatic, PuROLine, Crystal Quest, and Apec.

The included components provide clean and safe water, filtering out contaminants for crystal clear ice, fresher tea and coffee, better tasting foods, and healthier water for baby formula. The Alkaline Mineral Filter restores healthy minerals like calcium, magnesium, and potassium to balance pH levels and provide alkaline water.

The filters are easy to install, with updated quick connect fittings for faster replacement and easier installation. They are also made from durable polypropylene and contain granular activated carbon and carbon block filters for effective contaminant removal.
