Unauthorized Charcoal: GE fridges won't dispense ice or water unless your filter authenticates as an official ($55!) component

No it doesn’t. I’ve looked at the knock offs, but have yet to find one with the same NSF 53 rating that I felt comfortable about. Right now the MFW filters are $33 on Amazon (non rfid). But 6 months certainly isn’t 300 gallons of water for our house. I’d say 300 gallons would get us +9 months easily.
