Owned by Google, Nest has one of the best smoke detectors on the market. This smoke alarm also alerts you to carbon monoxide in the home, and even tests itself so you don’t have to remember.
A voice alert will give you a heads up before the alarm goes off, and it can tell the difference between steam from cooking and smoke from a fire. It can also connect to other Nest equipment, making this a useful addition to your smart home ecosystem.

Shopping for a smoke detector: Here’s what to know
Finding the best smoke detector for your home depends on your preferences and security needs. Here are a list of features to look for in a smoke detector:
- Sensor types: There are smoke detectors with photoelectric sensors, ionization sensors, and smoke alarms that come with both types of sensors in one product. Photoelectric sensors are better at detecting fast moving fires with plenty of flames. Ionization sensors are better at alerting you to smaller fires with more smoke. While both are great, fire safety experts recommend finding an alarm with both sensors for optimal safety.
- Battery powered or hardwired: Battery powered smoke alarms are easy to install, and provide power even through power outages. But you’ll have to change them out. Hardwired smoke detectors don’t require a battery to be changed, but can also lose functionality if the power goes out. Experts recommend finding a hardwired model with a battery backup to have all your bases covered.
- Dual functionality: While a simple smoke detector may be all you’re looking for, it’s more affordable than ever to find one with a carbon monoxide detector included in the smoke detector. It makes it more convenient because you’re only switching out one battery, and gives you more bang for your buck.
No matter the smoke detector you choose to best suit your home, it’s important to have a working model on every floor, including outside bedrooms and hallways. If it’s battery powered, change out the batteries regularly and make sure to test it as well. This is one simple home security option that can literally save your life.
