Buying Guide
Choosing a carbon monoxide alarm is a big step for home safety. Here’s a guide to help you pick the best one.

Look for alarms with advanced sensors. These are more accurate and react faster to dangerous levels. Some use electrochemical sensors for precise readings.
Alarm Sound:
Ensure the alarm is loud. A 85-decibel alarm is standard and can be heard from different rooms.
Display:
Some alarms have an LCD display. This shows real-time CO levels, giving you more information.
Backup Power:
For plug-in models, a battery backup is essential. This ensures your alarm works even if the power goes out.
Additional Features:
Consider alarms with test-reset buttons and low battery indicators. Some even detect other gases or monitor temperature and humidity.
Brand Reputation:
Choose trusted brands like Kidde or First Alert. They are known for reliable home safety products and often meet UL standards.

Check the warranty period and the alarm’s end-of-life signal. Most alarms need replacement after 5 to 10 years.
