2020’s Best Smoke Detectors and Alarms For Home Protection
The best smoke detectors and alarms
Best smoke alarms for every home
Best smart smoke detector and CO alarm: Nest Protect
- Mobile alerts & alarm control
- Seamless connection with other Nest products
- Split-spectrum sensor to detect multiple kinds of fires
- Motion sensor lighting
- Voice alarms that tell you where danger is located
Our favorite smart smoke detector is the Nest Protect because it integrates with other Nest devices, gives you mobile access, and includes carbon monoxide monitoring.
If you don’t have the budget for a monitored home security system, a smart smoke alarm is the next best thing. You’ll still get notifications on your mobile device if you aren’t home to hear the alarm go off, which means you can call for help and make sure someone gets to your house as quickly as possible.
Best dual-sensor smoke alarm: First Alert SA3210 Dual Sensor Smoke and Fire Alarm
- Dual sensors for multiple types of fires
- 10-year sealed battery
- Easy installation
- 10-year limited warranty
Not all fires are the same—some start slow and produce lots of dangerous smoke, while others get hot very fast and spread quickly without creating as much smoke as you may expect. This First Alert smoke alarm has a dual-sensor design so it will quickly detect both slow-burning fires and fast-moving fires. And with a battery that lasts for 10 years, you won’t have to worry about whether or not the batteries will run out every few months.
- Integration with other security system equipment
- Professional monitoring
- Mobile notifications
Many security companies offer smoke detectors, but Vivint is our top pick because the alarm connects with other home automation and security devices that come in handy whether you’re going about your normal day or dealing with a real crisis.
When your smoke detector is part of your monitored security system, you never have to worry about missing an alarm. If your smoke detector goes off while you’re hiking in the mountains without cell service or while you’re in the middle of a crucial presentation to project stakeholders, your security provider will still be there to send for help in an emergency—even if you didn’t see a notification on your phone.
Best budget-friendly smoke alarm: Kidde Battery Operated Smoke Alarm P9050
- Easy installation
- Affordable price
- Photoelectric sensor
- 10-year limited warranty
When price is an issue, we recommend the Kidde P9050 smoke alarm. Kidde has a strong reputation and offers reliable detectors you can count on to protect your home. Plus, since this one is so affordable, you’ll be able to get as many as you need to protect your entire home.
Most homes need multiple smoke alarms—not just one. And because buying four or five smoke detectors can add up, sometimes price becomes the deciding factor. If your budget is too tight for one of the smoke alarms listed above, that’s okay. After all, a basic smoke detector is dramatically better than no smoke detector at all.
What you need to know about smoke alarms
Should I get a hard-wired smoke detector or a battery-powered smoke detector?
In most cases we recommend choosing a wired smoke detector or a smoke detector with an extra-long battery life. Hard-wired smoke detectors are more reliable since you don’t have to worry about batteries dying. Plus, most wired smoke alarms have battery backups, so they’ll still work during a power outage.
However, battery-powered smoke detectors are much easier to install, so be honest with yourself—if easier installation is the difference between whether or not the smoke detectors will actually get placed in your home, battery-powered smoke detectors will work just fine.
Where should I put smoke detectors?
At bare minimum, you need at least one smoke detector and carbon monoxide alarm on every level of your home—basement, main living area, attic, etc.
Ideally however, you should place a smoke detector in every bedroom and in hallways outside sleeping areas.
Place smoke detectors about 10 feet away from appliances like ovens, clothes dryers, and dishwashers to reduce false alarms.
How often do I need to check the batteries?
Does it matter which type of sensor my smoke detector has?
There are two common types of sensors in smoke detectors: photoelectric sensors and ionization sensors.
Photoelectric sensors are best for detecting smoldering fires that produce lots of smoke.
Ionization sensors are best for detecting faster fires with lots of flames and less smoke.
Most smoke alarms use photoelectric sensors because they’re best for alerting you to dangerous levels of smoke, even if there isn’t a large fire.
