Smoke detectors are protected your life

Smoke alarms are among the most important security devices for your home. You never know when you'll need them, but when you do, they will literally save your life.

According to the National Fire Protection Association, the winter months are when homes are at higher risk of fire-involved accidents, driven by an influx of candles, holiday decorations and your furnace running nonstop.

The larger your home, the more fire alarms you will likely need, and the NFPA recommends that you install one on every floor, in each sleeping area, at the top of each stairway and stairway-adjacent ceiling if you're in a basement. After putting six smoke detectors to the test, we found the top three that we'd recommend if you're shopping for a new unit, or if you want to replace your old one.
