First night: 41 PPM. Old detector — green light, completely silent.
"I ordered it mostly to end an argument with my wife. Three days after installing it near the furnace, the display showed 41 PPM at 11 PM. Our previous detector had a green light and made no sound. Gas company was at our door by 7 AM. Cracked heat exchanger. We'd been breathing it for weeks."

Your Current Detector Only Has A Green Light. 

Don't Become Another Headline. 

1-

The green light on your detector confirms one thing: the unit has power.

It does not confirm what concentration of carbon monoxide is in your air right now. It does not verify that the sensor is still functional. It does not detect natural gas at all.

2-

And by design — by the legal standard every hardware store detector is built to — it will stay completely silent until CO reaches 70 parts per million. Below that threshold, it has no obligation to warn you about anything.

3-

The CDC documents headaches at 35 PPM. OSHA's workplace legal limit is 50 PPM. Your detector is certified to ignore both.

This is not a flaw. It is the standard.

4-

And it is connected to more than 400 American deaths every year — most during sleep, most in homes with detectors present and glowing green.

FAQs

My furnace was just serviced. Do I still need this?

Annual service reduces risk significantly — it doesn't eliminate it. Heat exchangers can develop fractures between service visits. Gas connections can shift with temperature changes. Flues can become partially blocked without triggering anything visible during inspection. Real-time monitoring covers what scheduled maintenance can't: what's happening tonight, between service calls.

I have small children. Does that change anything about how I should use this?

Children absorb carbon monoxide faster than adults due to their higher respiration rate relative to body weight. Symptoms — confusion, unusual lethargy, persistent headache — appear at lower concentrations and are harder to identify in children who can't articulate what they're feeling. For homes with children, early detection isn't just important. It's critical.

Will it alarm when I'm cooking?

ClearAir Guard's professional-grade sensor is calibrated to distinguish between normal cooking activity and genuine CO or gas accumulation. It is designed to alert you to actual danger — not to react to steam, humidity fluctuation, or the kind of minor air quality variation that causes false alarms in cheaper sensors.

How many units does my home actually need?

One per critical area is our recommendation: near your primary heat source, in the kitchen, in or immediately outside sleeping areas, and in any space where family spends significant time. The Complete Home 4-Pack covers the critical areas of most family homes. Larger or multi-story homes benefit from additional units — The Family Plan is designed for that.

What if it triggers when nothing is wrong?

If ClearAir Guard shows elevated readings, treat it as real until confirmed otherwise — evacuate the space and contact your gas provider. In our experience, real-time detection reveals genuine issues that standard detectors missed, rather than producing false alarms. The professional-grade sensor is calibrated specifically to minimize false positives from normal household activity.
