Aico Ei208 review

Product alert

Don't Buy this carbon monoxide (CO) alarm – it failed to sound in one of our carbon monoxide detection tests

When we tested this alarm, we were concerned to see that after being exposed to a large amount of CO, all three samples failed to recover and continue to detect the gas.

The Aico Ei208 passed all of our other gas detection tests, but based on the failures we saw in our lab, we have to make the product a Don’t Buy. Aico told us that it's concerned by this and that it takes all matters of alarm quality and reliability very seriously. It went on to say that all of its alarms are independently tested, that it hasn't had a problem with this kind of alarm since launch in 2010 and that it is confident its alarms meet the carbon monoxide alarms standard.

Reviewed

The Aico Ei208 carbon monoxide alarm failed to sound in one of our carbon monoxide tests and that's why we've made it a Don't Buy. In one of our tests, we flooded three of the Aico alarms with a catastrophic level of carbon monoxide to which they responded correctly and sounded. But later, when we tested them with a lower, but still dangerous level of the gas, none of the three alarms sounded. Aico told us that it's concerned, that it takes all matters of alarm quality and reliability very seriously, that all of its alarms are independently tested, it hasn't had a problem with these alarms since they were launched in 2010 and that it is confident its alarms meet the carbon monoxide alarms standard.
