The 2 Pack Wireless Electric Smoke and Co Alarm Detector from First Alert is one of the best detectors we tested, thanks to a combination of its advanced sensors, long battery life, and ease of use. The alarm's photoelectric smoke sensor is highly sensitive, and alerts immediately when smoke (and potentially carbon monoxide) is detected. The detector's CO sensor is also highly sensitive, and automatically tests itself every 2 minutes, so you'll always know if it's working properly. The alarm is also equipped with a test/silence button, and it also has a loud 85dB alarm, so it can be heard even outside. The alarm's battery lasts 10 years, which is much longer than most detectors, and it also has 3 levels of sensitivity, so it's suitable for any home. The alarm's LCD screen shows you how long the battery will last, and when it's time to be replaced. The alarm is also portable, so it can be taken outside, and it comes with a 2-year warranty.

Test-Hush Feature - silences the unit for approximately 8 minutes; tamper-resistant technology deters removal of the unit from the wall or ceiling
The Kidde Interconnected Combination Smoke & Carbon Monoxide Alarm is our first pick for budget-conscious consumers. This smoke detector has many of the same features as more expensive units, such as voice alerts, ionization technology, and a smoke alarm with 85dB sound. But its low price makes it an attractive option. The Interconnected Combination Smoke & Carbon Monoxide Alarm has 2 AA batteries, and its alarm volume is loud relative to its size. The detector's voice alarm is loud enough for an alert to be clearly heard in a sleeping baby's room. The Interconnected Combination Smoke & Carbon Monoxide Alarm also has a bright LED display, which makes it easy to identify which button to press when the detector is activated. This detector's primary flaw is its lack of a mute button, which can make it difficult to silence an alarm if an alert is heard during a sleep interruption. Battery life is also short, at only 6 months.

The SCO5CN is a combination smoke and carbon dioxide detector that does a decent job of detecting both. According to its manufacturer, it has a 95% detection rate, which is higher than average, but its rate of false alarms is average. Though its photoelectric sensor is sensitive, its sensitivity level is not adjustable, which means that it will trigger more frequently in rooms with thick draperies. Its lithium battery is good for up to 10 years, and First Alert offers 3-year warranties on all of its products. The alarm is low maintenance, and it's easy to install. And its 85-decibel siren is loud enough to wake you up if there's trouble. With its white finish, the SCO5CN blends in with most home decors. The SCO5CN is a good choice for a home with a variety of smoke, heat, and carbon monoxide risks.

The Kidde Nighthawk Carbon Monoxide Detector and Propane, Natural, & Explosive Gas Detector is a reasonably versatile detector. It's worth mentioning that this detector doesn't detect natural gas, so it's best used alongside a separate detector for natural gas. The detector also doesn't detect propane or natural gas, although it's fairly well-equipped for detecting carbon monoxide. The alarm is loud enough to wake you from a sound sleep, and the display is bright enough to see in low-light conditions. The detector also has three different mounting options, and it's powered by either AC or battery power. The AC-powered version has battery backup, although the battery backup feature seems to cause the detector to fail about once a month, so it's probably a good idea to keep the battery charged at all times. If you don't mind replacing batteries every month, or you don't mind taking risks, the Kidde Nighthawk Carbon Monoxide Detector and Propane, Natural, & Explosive Gas Detector is a reasonably versatile detector.
