"Next time you sear tuna or burn popcorn, you’ll be glad you have a Nest Protect smart smoke detector in your kitchen. The Nest Protect won the best overall category in our 2019 roundup of the best smart smoke and carbon monoxide detectors. If there is enough smoke to trigger the emergency alarm, you can quickly silence it from your smartphone via the Nest app—no chair climbing or towel waving required. Instead of a single alarm tone, the Nest Protect speaks in a clear voice to alert you about smoke, fire, or an abundance of carbon monoxide in an area of your home. Keep in mind that the National Fire Protection Association recommends placing your smoke alarm at least 10 feet from your oven, stove, or other cooking appliance to avoid any false alarms.
