5 Best Smoke Detectors for Home Use in 2021

A smoke detector is an essential safety device in your home. Not only do they alert you to a fire, but if one does occur, they can give you precious time to evacuate before the flames take over and potentially cause serious injury or even death. That’s why it’s important to make sure that your home has at least one working smoke detector installed on every level of the building—including outside and inside any attached garage or porch.

Factors to Consider Before Purchasing Smoke Detectors for Home

The type of detector

Ionization detectors are best for fast flaming fires, while photoelectric detectors are better at detecting smoldering slow burning fires. Every year there are many fires in homes where no alarms were sounded because there was no working smoke alarm present. The best type of detectors for home use are ionization-type units because they detect fast flaming fires better than photoelectric-type alarms which detect slow smoldering fires.

Long term battery solution

Hardwired or plug in with backup batteries instead of disposable ones. Batteries need to be replaced every five years for long-term battery solutions and four to six months for standard disposable ones

Location and age

Where the units will be installed should play a factor into what kind you buy as well as how old they are. Units over about ten years of age have limited ability to detect certain types of smoke particles that newer models can pick up on better.

Ceiling height

If your home has very high ceilings or lots of windows consider buying dual sensor alarms which come standard with both ionization sensors and photoelectric sensors*
