Best generator with a CO shutoff sensor

A CO shutoff sensor monitors carbon monoxide around the generator and stops the engine when it builds up to dangerous levels, which happens fast in or near enclosed spaces. Brands market it under different names. We kept every model whose manufacturer lists a CO shutoff.

How to choose

A backup, not a permission

The sensor does not make it safe to run a generator in a garage, a basement or near a window. Keep it 20 feet from the house with the exhaust pointed away, and put battery-operated CO alarms inside. Read our generator safety guide.

Mistakes to avoid

  • Placing the generator in an attached garage because it has a CO sensor.

Frequently asked questions

What does a CO shutoff sensor do on a generator?

It shuts the engine down when carbon monoxide around the generator reaches a dangerous level, for example if it is run in or too close to an enclosed space.

Do all new generators have CO sensors?

Not all, but most major brands now offer them on many models, in line with industry safety standards.

Do I still need CO alarms in the house?

Yes. Install battery or battery-backup CO alarms on every level and near bedrooms.
