How Do You Buy Carbon Monoxide Detectors?
Called “the silent killer,” odorless, tasteless carbon monoxide (CO) gas results from faulty combustion in a furnace, fireplace or gas range, or a car (in an garage). A CO detector is your only means of protection. Step 1 Shop for a CO detector. There are only three types; they’re all affordable ($30 to $50) and easy to install: Step 2 A biometric CO detector has a gel cell of synthetic hemoglobin that absorbs CO. The combination battery and sensor module must be replaced every two to three years, but the detector should last about 10 years. After an alarm, the sensor should clear itself within 2 to 48 hours when left in fresh air. If it is not cleared, it will sound again when put back in the detector. Sensors that don’t clear must be replaced. Step 3 A semiconductor detector is a plug-in device with an electronic sensor, and lasts from 5 to 10 years. Step 4 An electrochemical detector responds differently to different levels of CO exposure. Its self-powered battery doesn’t need to be
