"Our CO alarm went off at 2am and I had no idea what was happening. Got this one after and honestly it gives me so much peace of mind. Detects four things at once and just plugs right in."

Plug the detector into any standard 110V outlet. The built-in sensors immediately begin monitoring the air for carbon monoxide, natural gas, LPG, and smoke. When levels exceed safe thresholds, the alarm triggers instantly. No app required, no Wi-Fi needed, no setup beyond plugging it in.

1x 4-in-1 Plug-In Detector, 1x User Manual. That's it. Everything you need to start protecting your home today.

Q: What gases does this detector detect?
A: It detects carbon monoxide (CO), natural gas, LPG (propane/butane), and smoke. That's four threats covered by one device.

Q: Does it need batteries?
A: Nope. It plugs directly into a standard wall outlet. No batteries, no replacements, no dead detector surprises.

Q: How loud is the alarm?
A: Loud enough to wake you up. The alarm is designed to be heard from another room so you have time to react.

Q: Where should I place it?
A: Plug it in near your kitchen, garage, or any room with gas appliances. For CO, lower placement works best since CO is slightly heavier than air.
