10 Best Carbon Monoxide Meters 2025 in the United States

The X-Sense Smoke and Carbon Monoxide Detector Combo offers reliable dual protection by detecting both smoke and carbon monoxide, making it a practical choice for home safety. It features wireless interconnection, so when one alarm goes off, all linked alarms sound together, which is great for alerting everyone in larger homes. The device includes an easy-to-read LCD display that helps users monitor status and alerts clearly. Powered by a sealed 10-year lithium battery, it provides long-lasting, maintenance-free operation, so you don’t need to worry about frequent battery changes.

Made from heat-resistant and corrosion-resistant materials, it’s designed to be durable and dependable. The sensor type is photoelectric, which is effective for smoke detection. Although it's not Wi-Fi-enabled, the RF wireless interconnection still covers up to 24 devices, which is enough for comprehensive home coverage. At about 5.7 inches and weighing nearly 5 pounds for the six-pack, it’s relatively easy to install and move if needed.

This detector is a solid option for homeowners seeking a combination alarm with long battery life and multi-device connectivity, while those wanting smart home integration might look elsewhere.

The X-Sense Smart Smoke Detector Carbon Monoxide Detector Combo is a solid choice for anyone wanting reliable home safety with smart features. It combines photoelectric smoke sensing and electrochemical CO sensing, which helps provide accurate and quick warnings of smoke or carbon monoxide. The alarm is audible and designed to alert you promptly, while the device also sends real-time notifications to your phone via the X-Sense Home Security app, so you can monitor your home even when you’re away.

Response time is impressive, especially if you opt for the Protect+ subscription that offers professional monitoring and emergency dispatch within seconds. Battery life is excellent thanks to replaceable lithium metal batteries, which should last for years, making maintenance straightforward and cost-effective. The device is portable and easy to install since it’s battery-powered and doesn’t rely on hardwiring. However, it only works with 2.4 GHz Wi-Fi and cannot connect to a central hub, meaning each unit operates independently without communicating with others.

This product is well-suited for users who want a smart, dependable, and easy-to-manage detector with app alerts and sharing features, but it might be less ideal if you want devices that work together or support 5 GHz Wi-Fi.
