iSpring RO Replacement Filter Cartridge Pack + Greatwell RO Membrane

The iSpring F7-GAC 1-Year Replacement Supply Filter Cartridge Pack Set is designed for Standard 5-Stage Reverse Osmosis RO Systems. This pack includes a total of 7 replacement filters to ensure that the filters can be changed on schedule for a period of 1 year. The pack consists of 2x 5 Micron 10" Sediment Filters for the 1st Stage (FP15), 2x 5 Micron 10" Granular Activated Carbon (GAC) Filters for the 2nd Stage (FG15), 2x 5 Micron 10" CTO Carbon Block Filters for the 3rd Stage (FC15), and 1x Post Carbon Inline Filter for the 5th Stage (FT15).

The sediment filters remove dirt, rust, sand, and other particles, while the GAC filters absorb chlorine, halide, organic contaminants, odors, and other impurities that contribute to bad tastes and odors. The carbon block filters further remove any remaining chlorine, tastes, and odors, and the post carbon inline filter polishes the water before it is delivered to the faucet. It is recommended to replace the filters approximately every 6 months, except for the post carbon inline filter which should be replaced every 12 months.

Please note that the 1-year filter supply pack does not include an RO membrane, as the membrane only needs to be changed every 2-3 years. If you are looking for a filter pack that includes the RO membrane, you can consider the 2-year F15-75 or 3-year F22-75 supply pack. This filter pack is compatible with iSpring RCC7, RCC7P, and most other RO systems that use standard sized filter housings.

The iSpring Greatwell Reverse Osmosis Membrane is a high capacity 75 GPD membrane that fits standard under sink RO drinking water filtration systems. It is designed to remove up to 99% of over 1,000 contaminants, including lead, chlorine, fluoride, arsenic, asbestos, calcium, and sodium. The membrane has a capacity of 75 gallons per day at 50/60 psi and 77 degrees F, with feed water pressure ranging from 40 to 100 PSI and feed water temperature between 40 and 100 degrees F. The membrane has a length of 11.75" and an O.D. of 1.75", making it suitable for most standard under sink RO membrane housings. The updated FT15 post-carbon filters included in the pack feature a secure push-fit design for faster replacement.
