ISPRING 6-Month Replacement Filter Set for 6-Stage Reverse Osmosis Water Filtration Systems

The F4AK 6-month filter pack comes with a total of 4 replacement filters so the filters can be changed on schedule for 6 months. 1x 5 Micron 10 in. Sediment Filter (1st Stage, #FP15): Removes dirt, rust, sand, and other particles. Replace approximately every 6 months. 1x 5 Micron 10 in. Granular Activated Carbon (GAC) Filter (2nd Stage, #FG15): Absorbs chlorine, halide, organic contaminants, odors, and other impurities that contribute to bad tastes and odors. Replace approximately every 6 months. 1x 5 Micron 10 in. CTO Carbon Block Filter (3rd Stage, #FC15): Further removes any remaining chlorine, tastes, and odors. Replace approximately every 6 months. 1x Alkaline pH Remineralization Filter (6th Stage, #FA15): Adds 0.5 – 0.8 PH back to the water. Also adds back healthy minerals such as ionized calcium, magnesium, sodium, and potassium which were removed during the RO process. Replace approximately every 6 months. Note: The 6-month filter supply does not come with an RO membrane, as the membrane only needs to be changed every 2-3 years. To get a filter pack that includes the membrane, take a look at the 2-year F19K75 or 3-year F28K75 supply pack. This filter pack fits the ISPRING RCC7AK, RCC7P-AK, and most other RO systems that use standard sized filter housings including Flowmatic, PuROLine, Crystal Quest, and Apec.
