Typically available for $25 or less, the CO400 was the least expensive CO detector we tested, and it was also the fastest at detecting carbon monoxide at both concentration levels. It doesn't come with a digital display or any smart features, but it makes up what it lacks in fancy looks with performance and affordability.
If all you need is a carbon monoxide alarm that can reliably watch your back without leaving a hole in your pocket, then the First Alert CO400 is perfect for the task.īasic features include a single test/silence button and a very loud alarm. Most common CO alarms are designed to go off after the CO levels in an area have been above a certain threshold for a while. Having immediate and accurate access to this information can help you take swift preventive action before the alarm has a chance to react. Having a real-time display of the CO concentration is incredibly useful. However, the discrepancy between the two readings remained below 7%. The CO reading on the detector went a little above what our control was showing. The real-time CO reading is pretty accurate, taking only two minutes and a half to catch up to the reading shown in our control device. In average, it took a little more than 12 minutes to detect the presence of CO at 250ppm and just over 8 minutes to detect CO at 400ppm. This unit ranked third in our quickness of response test. The unit can be hung in the wall with two screws and its cord extends at least 6 feet, giving you a little flexibility as far as where exactly you can install it in your home. Just pick any outlet that is not controlled by a switch or dimmer, and that is at least 5 feet away from any fuel-burning appliance. This is a plug-in model that is backed-up by two AA batteries (Energizer E91 only). Highlights include a digital display that shows real-time carbon monoxide concentration in ppm and battery level, a test/silence button for weekly testing and a peak CO level button to show the highest carbon monoxide concentration detected.
At an average retail price right around $35, the CO615 from First Alert is the perfect carbon monoxide alarm if you're looking for handy features and decent performance at an affordable price.
