The absolute best smoke detector overall depends on your home’s existing setup, but testing from expert outlets like The Spruce and SafeWise points to and as the top choices for reliability and safety. The best options are 2-in-1 units that handle both smoke and carbon monoxide (CO).[3]

🥇 Best for most homes: Kidde 20SD10-V
🥇 Best if you need smoke + carbon monoxide: Kidde 30CUA10
This is my preferred choice if you want one device covering both hazards. It's hardwired with a 10-year battery backup and can be interconnected with other alarms.
🏠 Best smart option: First Alert SC5
If you want phone notifications, Wi-Fi, voice/location alerts, and smoke + CO detection, this is the standout. It is also the current replacement path for the discontinued Google Nest Protect.
🔌 Best straightforward hardwired smoke alarm: Kidde 20SA10
Photoelectric sensing, hardwired power, sealed 10-year backup battery, and interconnection. It's a particularly good choice if your house already has wired alarms.
If you're replacing the alarms in a typical house, I'd prioritize photoelectric + 10-year sealed battery + interconnected alarms, and add CO detection where appropriate. Photoelectric alarms are generally preferable for reducing nuisance alarms from cooking/steam and for detecting smoldering fires.
If you tell me whether your current alarms are hardwired or battery-only, and whether you want CO detection/smartphone alerts, I can narrow it down to the exact model I'd buy for your house.
