Consumer Reports Issues Caution Regarding Possible Risks in ‘Amazon’s Choice’ Carbon Monoxide Detector

As per Consumer Reports, Amazon has been made aware of the findings. The retailer “has taken down” the detector model “as it [examines] the safety concerns at hand,” and has also pulled similar items that Consumer Reports noted were comparable or identical to the defective Hembisen detector, including models from KH Alert, Koaabit, Yojock, and Vilfet. There are still questions regarding the retail giant’s method of confirming the safety and security of its diverse products, especially safety items. Regrettably, the report reflects wider patterns related to large online retailers and third-party platforms.

A defective detector presents lethal risks

Consumer Reports noted four hospitalizations associated with failures from the carbon monoxide detector in the U.S. government Safer Products database, which monitors unsafe consumer goods. The events, which took place in February and March 2026, resulted from the detector’s inability to inform users about critically dangerous CO levels. In one instance reported, two teenagers received treatment for carbon monoxide poisoning after “the device failed to emit any alarm or indicate any elevated readings even as CO levels reached perilously high amounts.”

The report underscores numerous customer reviews on the website detailing similar malfunctions, including one where a gas company staff member informed a customer about several false alarms attributed to Hembisen. Some individuals reported headaches, fatigue, dizziness, and other symptoms potentially linked to CO exposure. At the time of Consumer Reports’ investigation, the detector was highly favored, with sales exceeding 4,000 units the prior month.
