Gianmarco Chumbe
Experts recommend the First Alert CO400 as a budget-friendly carbon monoxide detector that runs on batteries and has a test/silence button. It does not have a digital display or smart features, but it was the fastest at detecting CO at both concentration levels, taking about 11 minutes to detect CO at 250 ppm and 7 minutes to detect CO at 400 ppm.
