If you are in the market for some new CO detectors, you might want to do a little research on the best brands. According to Consumer Reports there are some detectors that you need to pass on by and they found 3 that failed to work properly. These detectors were purchased from online retailers.
The three that failed are:
NetBoat WB_H3110061 LCD Portable Security Gas CO Carbon Poisoning Monitor (Amazon)
Foho YJ-806 LCD Portable Carbon Monoxide Poisoning Monitor Alarm (Amazon)
GoChange 882 LCD Portable Carbon Monoxide Poisoning Monitor Alarm (eBay)
Consumer Reports conducted tests for sensitivity at different concentrations of carbon monoxide. GoChange and Netboat failed to sound when exposed to carbon monoxide at a concentration of 100 parts per million. They should sound alarm 40 to 165 minutes at that level of carbon monoxide. At higher levels, the GoChang failed to sound. The Netboat did sound alarm but at 30 seconds and not the normal time frame of 4 to 15 minutes .The third one tested FoHo sounded to quickly to low levels of carbon monoxide, and sounded 1 1/2 minutes at higher concentrations.
If you have purchased one of these CO Detectors from eBay, they do have a money back guarantee. If you purchased one of these from Amazon, they will work with consumers who may have purchased these alarms under the terms of its return policy.
Consumer Reports has rated these three products as Don’t Buy, Safety Risk.
Amazon and eBay have both been contacted concerning these finding and they have responded to the finding by removing all these products on their website. However, there can be other sites that still sell these items. Look for the the UL certification on CO detectors, to make certain that they have passed UL’s carbon monoxide alarm standard.
