The Best Smoke Alarms: Reviews & Comparisons of Top Rated Smoke Alarms

by Caitlin McCormack | Last Updated Feb. 12th, 2016

Given that every 85 seconds a home fire in starts somewhere in America, it makes sense to have a working smoke alarm installed in your home. It can help cut your risk of dying in a home fire by more than 50%. Even still, nearly 5 million households in America say they do not have a smoke detector in their home.

By simply installing a working smoke detector in your home, you and your family can be alerted to dangerous levels of heat and/or smoke in the event of a fire and escape to safety before something tragic happens. It’s recommended to have one alarm on each level of your home, and directly outside or in any bedrooms.

In fact, depending on where in America you live, it’s likely by law that you need to have a working smoke detector installed in your home and depending on your state, even the type of alarm might be specified. Increasingly, more and more states are making hardwired units mandatory, and with available battery backup, you can rest assured you’re always protected. Don’t forget to test monthly and if necessary, replace your batteries with each time change.
