3/2023 – These (photo below) detectors do not work and are unsafe. Detectors involved in the CPSC alert are of sold by CUZMAK and GLBSUNION and are made in China. If you have them, you’re being told to stop using them and dispose of the alarms immediately and install new, working ones. Always best to purchase any carbon monoxide detector locally, at Home Depot, Loews or similar retailer.
More information here on the recall.
These poorly made devices are made of white plastic, with approximate dimensions of 4 x 1.5 x 4 inches, and features a digital display. They are advertised to detect dangerous levels of carbon monoxide and alert with a flashing red LED and a loud alarm pattern. They do not work as advertised. These are sold on Amazon.
We have seen this type of CO detector in some homes in Southern California. If you think you may have one, check the photo below to be sure.
Here also is our best to worst carbon monoxide list. We have been calling out this detector for years as un-safe. This detector is one of the worst around.
Carbon monoxide sensitivity tests performed on the GLBSUNION and CUZMAK detectors by CPSC found here that they failed to alert when exposed to pre-determined concentrations of carbon monoxide (400 ppm), in violation of UL 2034, a voluntary safety standard.
Call us if you have any questions about these types of poorly made CO detectors at 310-800-4418.
