We keep one in our RV year-round. It's small, accurate, and loud enough to wake us even when the heater is running.

Why AirShield Smart Portable CO Guard Stands Out
AirShield combines pro-grade electrochemical sensing, dual gas detection, loud 85 dB alarm, and portable travel design. Others use weaker sensors or lack battery backup, leaving gaps in safety and peace of mind.
