Buying Guide

Power type and backup

Choose battery-powered units or plug-in detectors with battery backup to ensure continuous operation during outages and when outlets are limited in apartments

Sensor technology

Prefer electrochemical sensors for reliable CO detection over time; check manufacturer specs for sensor type and expected service life

Digital display and readout

A clear LED or digital display shows CO concentration, which helps you assess risk quickly compared with models that only sound an alarm

Coverage and pack size

Use multi-packs or place detectors in key areas—near sleeping rooms and common areas—so the number of units matches apartment layout and occupancy

Installation and portability

Select plug-in options for easy mounting where outlets are available, or compact battery-only units when drilling is restricted by lease rules
