The Problem No One Talks About
Your CO Detector Was Never Truly Designed To Save You
Here's what the research says, and why it matters for you and your family:
Children absorb CO 3x faster
Children's bodies are smaller and breathe faster. A child absorbs up to 3x more than an adult in the same room. At a CO concentration where an adult gets a slight headache, children can already lose consciousness. But the CO alarm threshold was designed for the average adult. Not a child. Health safety reports show that young children have the highest rate of carbon monoxide poisoning fatality. Most are found in their bed, while their detector hasn't gone off.
Health & Safety Research Data; Journal of Pediatric Emergency Care
4 Hours at 30 PPM Is More Dangerous Than 1 Hour at 70 PPM
A standard CO detector set to the minimum 70 PPM threshold can sit at 69 PPM for days and never make a sound. So your family can be breathing CO at levels which can kill within a few hours, without ever knowing. In fact, just 4 hours at 30 PPM is more dangerous than one hour at 70 PPM. Which means the current 70 PPM legal minimum is completely inadequate.
Global Carbon Monoxide Poisoning Data; Journal of Pediatric Emergency Care
Safety Standards set decades ago
The 70 PPM standard wasn't written by doctors or public health officials. It was written in response to atmospheric temperature inversions that happened in major metropolitan areas, causing a wave of nuisance alarms. Emergency crews and gas companies were overwhelmed. So standard-setters raised the alarm threshold to stop the phone from ringing. And detector manufacturers exploited it and lobbied to not update that standard; it hasn't been updated since.
Safety Standards Petition & Regulatory Data
Over 100,000 CO Poisonings Yearly
Over 100,000 people are poisoned by CO every year globally. Most of them had a detector. A peer-reviewed study tested 30 of the most common detectors in households and found a high overall failure rate, including models that failed unsafe meaning they never alarmed at all, not even at 70 PPM. Because in this industry, there is no meaningful enforcement, no post-sale testing, and no accountability. So some manufactures don't even build to the minimum standard and still get away with it.
Peer-Reviewed Study: Residential CO Detector Failure Rates; Global CO Poisoning Surveillance Data
85% of CO poisoning victims had no issues in their appliances beforehand.
Most people assume CO poisoning requires an obviously broken or old appliance. It doesn't.
New, well-maintained appliances can develop hairline cracks that even inspections can't check. And appliances can develop faults the day after an inspection.
CO leaks are unexpected. A furnace can run perfectly for 6 years and suddenly develop a crack overnight. A flue can shift in a cold snap. A burner can come out of a service slightly out of tune and nobody notices.
The families who end up in emergency rooms weren't negligent. They had a yearly inspection, they bought reliable appliances. They did everything right.
They just didn't have a detector that could tell them what was happening before it was too late.
Victims and associations have been fighting to change the law for years.
Doctors, lawyers, health safety organizations, and survivor associations have all formally demanded that safety authorities update the CO alarm standard. The standard still hasn't moved.
NCOAA & Earthjustice — Petition to the CPSC
December 2024The National Carbon Monoxide Awareness Association, represented by Earthjustice, formally petitioned safety regulators to lower alarm thresholds and mandate accurate digital displays.
Filed December 17, 2024. Still Pending.CPSC — UL 2034 Standards Technical Panel Meeting Log
January 13, 2025An official meeting log from safety regulators discussing proposed changes to UL 2034 - including lowering display thresholds below 30 PPM. The meeting confirms that regulators are actively aware the current standard is inadequate, and that industry resistance remains the primary obstacle to change.
What Happens To Your Body At Every CO Level Below 70 PPM
Based on peer-reviewed exposure data from global health and safety research organizations.
0-15 PPM
CO starts getting into your blood, displacing oxygen. You feel slightly foggy and tired. Nothing big.
16-29 PPM
Headaches. Fatigue. Strong brain fog. You think you're getting sick. Your children already are and they want to go to bed.
30-50 PPM
Confusion. Nausea. Slowed reactions. Your body knows something is wrong but your brain can no longer process what. Young children and the elderly often lose consciousness in this range.
51-69 PPM
You feel severely drunk. Disoriented. You can barely keep your eyes open. Most people at this point cannot think clearly enough or move well enough to evacuate. And their kids are already unconscious, but they can barely get out themselves, let alone get their kids out. That's what happens to most adults, especially those with lower body weight.
70 PPM
Your standard detector alarms.
If you have TrueDetect, you'll see CO building on the screen and get notifications to your phone at just 1-29 PPM - days before it becomes dangerous. And at 30 PPM, your alarm will go off. Hours before the real symptoms. Before the confusion. Before the exhaustion. Before your kids lose consciousness. While you can still get everyone out.
The First CO Detector Built to Save You. Not Just to Meet the Minimum.
Alarms at 30 PPM, Not 70
Every standard detector is legally built to stay silent until CO reaches 70 PPM. TrueDetect alarms at 30 - where real damage begins. That's hours before danger. Hours your family is still clear-headed enough to get out.
Live Display Starting at 1 PPM
Standard detectors show nothing. Even the ones with a display can't read levels below 30 PPM. TrueDetect shows exact CO levels from 1 PPM, so you can see a slow buildup weeks before it becomes an emergency, when it just makes you feel off.
Alerts Every Phone in Your Home
The moment low levels of CO start climbing, TrueDetect sends your phone a notification - telling you what the CO level means and what to do. And in an emergency, at 30 PPM, it triggers an emergency alarm on every phone in the house. Even on silent/sleep mode.
10-Year Life.
Standard detectors quietly expire after 5 years. Which is why 30% of households unknowingly own detectors that already expired. TrueDetect lasts 10 years, and sends you a notification once it expires. So you're never unknowingly unprotected.

Got CO Poisoned Because My Detector Failed. Never Again.
Was CO poisoned two years ago. I was lucky that my wife got back home and found me. My detector certainly didn't beep. Bought TrueDetect the same week. This is the only one that can give me peace of mind after what happened. And I thought to write this review now, because I hate to think that some people will wait until it happens. Don't be that person. Especially if you have kids, don't rely on luck. Get your home protected.
★★★★★
After what happened to my friend's daughter, this was non-negotiable
My friend lost her 7 year old to CO poisoning last year. She told me to get this one as she did. I did. Honestly I sleep better now. The app is a nice bonus too. Really impressive device. Highly recommend.
★★★★★
Bought It For My Parents
My dad's 74 and my mom has heart issues so I wasn't taking any chances. The app is the best part for me — I get the alerts on my phone too so I can keep an eye on their house without calling them every day. Worth every penny for the peace of mind alone.
★★★★★
Saved my life!
This thing literally saved my life. I had a headache and my son felt sick for an hour and then TrueDetect alarmed. We quickly exited the home. My old detector? It was still on the wall but never made a damn sound. If I didn't have this, we would've gone to sleep and that would've been it. Be smart and get your home protected as well.
★★★★★
I experienced what 70 PPM is like, so this detector was a godsend
I survived CO poisoning in 2019. Spent 3 days in the hospital and had neurological symptoms for months after. The difference between 30 PPM and 70 PPM is not a small thing. I experienced it. I literally tell everyone I know to get this detector. Until the safety standards update, this is the only one you can trust.
★★★★★
The only one I recommend as an HVAC
I recommend this at almost every house I service. That's the only one that I can actually say gives you 100% safety. Nothing beats it. Some people push back on the price, but it lasts twice as long as a $40 detector... so it's actually not more expensive.
★★★★★
The Phone Notification Saved My Life Days Before.
I just had a slight headache one afternoon. Then my phone sent a notification saying CO levels in my house were at 13 PPM and marked it unhealthy. Called an HVAC tech the same day. He found a leak and told me it could have slowly poisoned me for weeks before it ever became acute. I didn't even know that was possible. Having that live PPM readout on my phone caught a problem before anyone got hurt.
OUR MISSION
Spreading awareness, one event at a time.
We don't spread this message alone. Changing how people think about CO safety requires doctors, first responders, and safety leaders who share the cause. That's why we show up at safety conferences, community events, and industry summits. Meeting the people who can help us get real protection into every home.
