About Us
About Us
For more than 25 years, we have helped homeowners and professionals choose the right carbon monoxide detector. Carbon monoxide is invisible and odorless, and the detector you choose decides how early you find out it’s present.
Why we focus on low-level detection
Most store-bought CO alarms are built to the UL 2034 standard, which doesn’t require them to sound until CO reaches 70 ppm. That’s fine for an emergency, but it can miss the lower, longer exposures that cause headaches, fatigue and nausea, especially for infants, older adults and anyone with heart or lung conditions. We specialize in detectors that show you what’s in the air much sooner, so you can act before it becomes a greater emergency.

- Home & office: Defender and CO Experts low-level monitors, plus UL 2034 listed alarms for code compliance
- RV, boat & travel: compact portable detectors that go wherever you go
