FAQ

Q: Is the Murdock RWF3 (7012-318-000) a direct replacement for the older WF-3 filter?

A: Yes — the RWF3 (7012-318-000) is the official direct replacement for the existing WF-3 filter in compatible Murdock drinking fountains, water coolers, and bottle fillers. It uses the same quick-connect fittings with an auto shutoff valve for easy, tool-free swap-out.

Q: Is this filter discontinued, and should I consider an upgrade for PFAS/forever chemicals?

A: The RWF3 is listed as discontinued in Murdock's current resources (as of 2025 updates), though it's still available while stock lasts. It excels at lead, chlorine, and cyst reduction. For modern protection, upgrade to the newer Murdock WF3000 / RWF3000 series (2-stage, 3000-gallon PFAS reduction).
