"At 2 AM, TrueDetect alarmed at 45 PPM. Fire department found a cracked heat exchanger. Our old detector was still silent. The firefighter said if we'd waited for that one, we might not have woken up."

Is your home producing CO right now?

🚗 Attached garage?

Every time you start your car, CO seeps through the shared wall into your home. Even with the door open.

🏚️ Home older than 15 years?

Heat exchangers crack over time. They can leak CO for months before anyone notices.

🔥 Gas, propane, or oil heat?

Any fuel-burning system produces CO. One blocked vent, one small crack – it's already in your air.

🪵 Fireplace or wood stove?

Blocked chimneys push CO back into your home instead of up and out.

The Silent Gap Where Your Family Is Harmed

Most US homeowners aren't warned about their late alarming detectors.

 

It's not their fault. It's what the standard designed.

 

If your current CO detector shows UL 2034 written on the back…

 

It means your detector is built to stay silent until 70 PPM.

 

And stores like Walmart, Target, Home Depot?...

 

They're all required to meet this standard.

Here's what 70 PPM does to your family…

At 30 to 50 PPM, children and pregnant women are already experiencing symptoms.

 

Headaches. Fatigue. Nausea.

 

Things that get dismissed as a cold, a bad night's sleep, a stressful week.

 

At 70 PPM, the level your detector is finally allowed to make a sound… the damage has already been building for hours.

 

This single problem is responsible for over 100,000 ER visits each year.

Frequently Asked Questions

Have questions? We’re here to help

Why does TrueDetect cost more?

$20-$30 detectors at Walmart, Target and Home Depot use a cheap semiconductor sensor that's built to alarm at 70 PPM. TrueDetect uses a professional-grade electrochemical sensor - the same technology HVAC technicians carry in equipment costing $400+. It alarms at 30 PPM, has a real-time display, lasts 10 years, alerts you the moment it needs replacing. At just $69.95 - you're paying $7 a year for a decade of safety.

What if my current one works fine?

When did you last check the expiration date? Most detectors expire after 5-7 years but keep displaying a misleading green light. Even if it works, it won't sound until CO hits 70 PPM – hours after your family already has symptoms. So it's not broken, but it's guaranteed to alert when it's already too late.

Will I need more than one?

One covers a single floor. But CO builds throughout the house. One near your furnace doesn't protect the bedroom where your kids sleep. One on the ground floor can't alert you upstairs. Cover each floor. Cover the attached garage if you have one.

Where do I put it?

Start within 15 feet of bedrooms – where CO poisoning happens most, while you're sleeping. One near your furnace or main living area. One on each floor. Near the fireplace or attached garage if you have either.

Will it go off every time I cook?

No. TrueDetect knows the difference between a brief CO spike from your gas stove and dangerous buildup from a cracked furnace leaking for hours. You get alerted to real threats.

How long does it last?

10 years. With daily self-diagnostics that tell you when it's time to replace it. Your current detector has an expiration date too. It just doesn't tell you when it's passed.
