iSpring RCC7 / RCC7P filter FAQ
What filters does the iSpring RCC7 use?
Five stages: a 5 micron sediment filter (iSpring FP15), a GAC carbon filter (FG15), a 5 micron CTO carbon block (FC15), a 75 GPD membrane (MC7) and an inline post-carbon filter with ¼" quick-connects (FT15). Stages 1 to 3 are standard 10" × 2.5" cartridges.
Do the RCC7 and RCC7P take the same filters?
Yes. iSpring sells one replacement pack for both the RCC7 and RCC7P. The RCC7P adds a booster pump, but the filters and membrane are the same size.
How often should I change the RCC7 filters?
Change the sediment, GAC and carbon block filters every 6 to 12 months and the inline post-filter about once a year. The membrane usually lasts 2 to 3 years. Change sooner if flow drops or taste changes.
Will these filters fit other iSpring 5-stage systems?
Most iSpring under-sink RO systems use the same standard 10" × 2.5" housings and 1812 membrane. iSpring lists the FT15 post-filter for the RCC1UP, RCB4T, RCS5T, RCB3P and RCC7. Not sure? Call (714) 541-6600.
