Does the DuroMax CO Alert models have CO shutoff?
Last reviewed July 2026.
A system is advertised; no named standard stands behind it. DuroMax advertises CO Alert shutdown on newer models; we could not locate a named standard citation (checked 2026-07-14). Same middle tier, same exit: publish the standard, move up.
The facts on file
| Verdict | Advertised, no standard — Shutoff advertised — no named standard located |

How to read this
Two ANSI standards govern generator CO safety, and they are not equal claims: UL 2201 is third-party certified with a public listing (and per CPSC's modeling, machines built to it would avert nearly 100% of generator CO deaths); ANSI/PGMA G300 conformance is stated by the manufacturer (~87% in the same modeling). An advertised shutoff with no named standard is better than nothing and checkable against nothing. See the two standards compared — and remember a shutoff is not permission.

Generator Score indexes CO-shutoff systems against the two ANSI standards and the public record (UL listings, manufacturer citations, CPSC data), with attribution — we test nothing and give no safety advice. No CO-shutoff system makes a generator safe to run indoors, in a garage, or near openings — CPSC's placement guidance (outdoors only, 20+ feet from the home, exhaust pointed away) is the operative document, and a shutoff is a backstop for mistakes, not permission to make them. If a maker publishes a standard citation or a listing appears, the page changes — the record wins.
