FAQs
Will this fit my system?
Yes, if you have a GreenMachine PT‑4GR/PT‑4G (4‑Stage, 50 GPD). For PT‑5GR (5‑Stage), order FK‑101G instead.
Do I need to change the RO membrane now?
Not every year. Replace the Revtex 50 GPD (MAD‑4230) when TDS reduction drops or about every 2 years on average.
What’s special about GreenBlock?
Vertex notes the GreenMachine line uses NSF/WQA‑certified GreenBlock carbon made from eco‑friendly coconut‑shell media.
