iSpring F7-GAC RO Replacement Filter Cartridge Pack + iSpring FA15 Alkaline Filter Cartridge

The iSpring F7-GAC 1-year filter pack comes with a total of 7 replacement filters, allowing for scheduled filter changes over the course of a year. This pack includes:

2x 5 Micron 10" Sediment Filters (1st Stage, #FP15) to remove dirt, rust, sand, and other particles, which should be replaced approximately every 6 months.

2x 5 Micron 10" Granular Activated Carbon (GAC) Filters (2nd Stage, #FG15) to absorb chlorine, halide, organic contaminants, odors, and other impurities that contribute to bad tastes and odors, which should also be replaced approximately every 6 months.

2x 5 Micron 10" CTO Carbon Block Filters (3rd Stage, #FC15) to further remove any remaining chlorine, tastes, and odors, and should be replaced approximately every 6 months.

1x Post Carbon Inline Filter (5th Stage, #FT15) to polish the water from the tank before it is delivered to the faucet, which should be replaced approximately every 12 months.

It's important to note that the 1-year filter supply does not include an RO membrane, as the membrane typically only needs to be changed every 2-3 years. If you require a filter pack that includes the membrane, consider the 2-year F15-75 or 3-year F22-75 supply pack.

This filter pack is designed to fit the iSpring RCC7, RCC7P, and most other RO systems that use standard sized filter housings, including Flowmatic, PuROLine, Crystal Quest, and Apec.

Additionally, the iSpring FA15 Alkaline Water Filter Cartridge can be used with this RO system. This inline cartridge with mineral balls and calcite media improves the pH value of the RO water, which can be slightly acidic after the reverse osmosis process. It also adds back healthy minerals such as ionized calcium, magnesium, sodium, and potassium, which were removed during the water purification process. The alkaline filter can increase the pH value of the RO water by 0.5 to 1.2, helping to minimize fluctuations in your body's pH. The restored minerals from the alkaline filter will slightly increase the TDS (Total Dissolved Solids) value, typically between 10-20 ppm.

The iSpring FA15 Alkaline Filter has a service life of 6 months or 1,500 gallons, whichever comes first. It is designed to be compatible with most water filtration systems, including RO systems from various brands.
