Smoke alarms save lives. Protect what matters most with the top fire and smoke alarms on the market. It’s easy to take smoke alarms for granted, but they can save your life—and your home. Below, you’ll find the best smoke detectors on the market, plus other fire safety information that can keep your family protected.
While Google’sNest Protect is pricey, it does it all. It detects smoke particles, carbon monoxide, and heat. It’s also not hard-wired, making it easier to install. Like other members of the Nest family, the Nest Protect is Wi-Fi connected and sends alerts to your phone when it detects a problem. And instead of sounding an annoying alarm, it uses a clear human voice to alert you of danger.
On top of that, its self-monitoring system performs 400 safety checks per day to ensure it’s in tip-top shape.
First Alert Onelink is a smart alarm that detects both smoke and carbon monoxide. At first, adding features like Alexa and Apple HomeKit compatibility may seem silly, but they’re quite useful. Smoke detectors connected to your smart home hub are able to alert your phone, so you know when there’s an emergency even when you aren’t home.
To top it off the First Alert Onelink also has a ten-year battery life expectancy.
This First Alert smoke alarm uses a dual sensor to detect multiple kinds of fires and decrease false alarms. It’s also hardwired with a battery backup, so you don’t have to worry about power failure.
Say goodbye to shrieking beeps while you’re cooking or after a hot shower. The First Alert BRK 3120B comes with a photoelectric sensor that’s sensitive enough to tell the difference between everyday activities and real threats like a smoldering fire.
Although this smoke detector has two smoke sensors, it doesn’t come with carbon monoxide detection.
This is the second Kidde smoke alarm to make our list, and it’s the most affordable. The Firex is easy to install and can be interconnected with other alarms to create a full-house smoke detection system.
Changing batteries has never been easier. It’s simple to keep this smoke detector ready for action with the slide-load battery door on the front.
The Firex has only an ionization sensor. While this provides early detection for fire particles, which is useful in a flaming blaze, it doesn’t provide accurate detection for smoldering fires.

What to Consider when Buying a Smoke Detector
Fires happen every day. In 2016, a house fire was reported every ninety seconds.1 If you have smoke detectors in your home, you’ll have a better chance of getting everyone out safely. While any smoke detector is better than none, there are a few things to look for when buying a new smoke alarm.
The best smoke alarms can detect smoke particles, flames, and carbon monoxide. A multifunctional alarm can save you battery life or energy from your house for hard-wired smoke detectors.
While classic ionization and photoelectric smoke detectors are helpful, smart smoke detectors are the cutting edge in fire safety. They communicate through apps and deliver alerts to your phone or other mobile device if an alarm sounds. Smart alarms can talk to each other too, so you’ll know exactly where the fire is when an alarm is triggered. The only downside is that smart devices are more expensive.
If your home’s power goes out, you still need to know if there’s a fire or smoke emergency. Hard-wired smoke detectors need to have a backup battery or some other backup power source to keep them running. And battery powered smoke detectors should have a test button or chirp when the battery starts to drain.
Types of Smoke Detectors
Smoke alarms typically have three types of sensors: ionization, photoelectric, and dual. Here are the main differences between the three.
A type of smoke alarm sensor that uses light to detect smoke. When smoke particles are suspended in the air (as with a smoldering fire) the particles scatter the beam of light in the sensory chamber, which sets off the alarm.
This type of smoke alarm sensor uses radiation and an ionization chamber to detect smoke. The ionizing radiation helps detect small amounts of smoke in the air, as with a flaming fire. When smoke enters the sensor chamber, the current of the ionizing radiation is disrupted, which triggers the alarm.
Dual sensors include both photoelectric and ionization sensors. These are considered the safest smoke and fire detection devices. Because they detect both flaming fires and smaller, smoldering fires, it’s unlikely that any fire-related danger will get past these double-duty sensors.
Tips for Smoke Detector Use
Smoke alarms can save a life, but they have to beproperly installed and maintained. Don’t risk your family’s safety—use these tips to keep your smoke detectors in tip-top shape.
Between 2009 and 2013, dead batteries caused 31% of smoke alarm failures in home fires where a battery-powered smoke alarm was present.2
Nest reports that nine out of ten people don’t check batteries. This is dangerous! A smoke detector won’t do you any good if it isn’t working, so make sure to check your batteries every month and use the “test“ button intermittently to ensure proper function.
Arm Every Level
The National Fire Protection Association (NFPA) recommends putting a smoke detector on every level of your home: in every bedroom, outside every sleeping area, and in your basement. On floors without bedrooms, install alarms in the living area or near stairways.
If you have a large home, consider adding even more to cover the whole footprint.
Smoke rises. It’s important to put your smoke detectors within a foot of your ceilings and ten feet from cooking areas.
For vaulted ceilings, avoid putting smoke detectors in the “pitch” of the roofline. Instead, mount fire alarms three feet below the ceiling so they can accurately read smoke.
Never Run Out of Batteries
Set up recurring delivery for smoke alarm batteries on Amazon. That way, you’ll always be ready to replace a dead battery in your smoke alarm. Time the delivery schedule to match regular smoke alarm maintenance so you’ll never overlook changing out old batteries.
Keep It Clean
Dirt and debris interfere with the sensors on your smoke alarm. Dusty buildup can lead to false alarms or delayed detection during an emergency. Whether you have a photoelectric alarm or an ionization detector, regular cleaning will keep your smoke alarm in working order.
Keep smoke alarms away from windows, doors, and air ducts. Drafts can disrupt the operation of smoke detectors and increase the occurrence of nuisance alarms.
The United States Consumer Product Safety Commission found that interconnected smoke alarms do a better job of detecting fires and alerting all occupants to danger.3 When it comes to safety, taking the extra step to install and connect hardwired smoke detectors is definitely worth it.
To determine the best smoke alarms of 2018, we scoured industry research and evaluated product features, performance, and specs. We consulted the National Fire Protection Association and US Consumer Product Safety Commission for guidance, and pored over expert ratings and real customer reviews. Our top five smoke alarms were selected from twelve different devices that were compared for reliability, effectiveness, price, and customer satisfaction.
