Best Smoke Detector

Smoke detectors are an essential part of any household and frequently mandated by law to be included in rental properties. Although many people associate smoke alarms with cheap units that go off way too often (especially if things go awry in the kitchen) modern alarms are generally sophisticated enough to tell when there's a real threat, reducing the amount of nuisance alarms.

Alarms can vary quite widely in their performance and price, with higher-priced models often including detection for both smoke and carbon monoxide, as well as the ability to network alarms together for a more comprehensive household alarm system. These best smoke detectors incorporate both audio and visual alarms, as well as the ability to detect smoldering fires, full flames, and carbon monoxide. They are also easy to install and test, while including a mute button to quickly handle any false alarms. Not all of our picks detect multiple types of threats due but all offer the reliable ability to detect a fire threat.

    Why it's best:

    The Kidde KN-COSM-BA is an excellent all-around smoke detector, with the ability to detect both fires and carbon monoxide. This battery-operated alarm is quick and easy to install, and includes a test/reset button to ensure that the unit is working properly. A hush feature is also included to quiet any false alarms.

    The KN-COSM-BA is a talking alarm, which means that it will verbally identify the type of hazard detected. This allows for a quicker appropriate reaction to the type of threat present. A low battery and end-of-life feature causes this smoke detector to "chirp" when the battery is low or the alarm has reached the end of its seven-year life span, allowing you to always be sure that the detector is functioning properly.

    First Alert SA320CN Double Sensor Battery-Powered Smoke and Fire Alarm

    Most experts recommend having alarms that use both ionization and photoelectric sensors, to detect both smoldering and flaming fires as soon as possible. While most people are forced to purchase separate units for this, the First Alert SA320CN combines the two into a single smoke detector, making this a highly recommended choice. Read Full Review

      Why it's best:

      The First Alert SA320CN is one of the relatively few smoke detectors to offer dual dire detection. This smoke detector uses both ionization and photoelectric smoke sensors because while most detectors use only ionization sensors, photoelectric sensors are better able to detect smoldering fires before they erupt into large flames. Many professionals recommend that every home have either both types of detectors or an all-in-one unit such as this for utmost safety.

      The SA320CN utilizes cutting edge technology to better distinguish real threats from false alarms, although a mute button allows for quick silencing of nuisance alarms. This battery-powered smoke detector does not offer carbon monoxide detection, but its dual sensor technology makes its slightly higher price tag well worth the investment.

        The First Alert SC9120B can be networked with other smoke detectors to create a household fire and carbon monoxide safety network. This ability to connect the detector with other devices allows for added peace of mind, since when one alarm goes off, it will signal to others elsewhere in the house to go off as well. The SC9120B uses both visual and audible warnings with separate indicators for smoke or carbon monoxide, while being programmed to ensure that nuisance alarms are few and far between. A silence/test button is also included.

        Although the SC9120B is a wired device, it comes with a battery backup to ensure functionality even during a power outage. Although this smoke detector is pricier than most, its networking ability and smoke and carbon monoxide detection capabilities are worth the investment.
