The dangerous low levels of carbon monoxide that standard detectors completely miss can be devastating to an already-fragile body. TrueDetect catches them from as low as 1 PPM — so if a leak ever starts, you're protected long before it could do harm.
365-Day 100% Money-Back Guarantee. If for any reason you're not satisfied, you'll get a full refund.
"Between the three of us, our house is full of people who can't afford a carbon monoxide leak. I have COPD. My husband had a stroke two years ago. And my mother, who lives with us, is in the early stages of dementia.
For years I figured the detector on our wall had us covered. Then I found out it only alarms once carbon monoxide reaches a level dangerous to healthy people — and for fragile bodies like ours, the harm starts long before it ever gets that high. The low levels that could hurt us most are the exact levels it's built to ignore.
I ordered 4 TrueDetects the same day and put them in every room that matters. Now if a leak ever does start, we'll know long before it could ever hurt any of us. That peace of mind is worth everything."
TrueDetect shows you the exact carbon monoxide level in your home at all times — on a bright digital display, updated every second, from 1 PPM.
So you're never left unprotected if a leak ever starts. You just look at the number — and you'll know the moment anything changes in your air, any time of day or night.
Most $25 detectors use cheap metal oxide sensors that degrade over time and can't reliably measure low CO levels at all.
TrueDetect uses hospital-grade electrochemical sensors — the exact technology used in emergency rooms, fire departments, and professional HVAC equipment. Accurate from 1 PPM.
If CO levels ever spike to a real emergency, TrueDetect alarms at 30 PPM — the same threshold used in hospitals and fire stations.
Not 70 PPM, when your judgment and mobility are already compromised. Paired with a loud 85dB audible alarm and a visual warning you can see from across the room.
For most people, a standard detector is "good enough" — because most people can survive a major leak long enough to get out. But if your body is already vulnerable, you don't have that margin.
The low levels a standard detector ignores are exactly the levels that can do you real harm. TrueDetect is built to catch them — so even the person who can least afford a leak is protected.
"In 30 years of emergency medicine, I've learned that carbon monoxide doesn't treat everyone equally. A leak that barely affects a healthy adult can be devastating to someone whose body is already vulnerable — and the standard detector on most people's walls won't make a sound until levels are high enough to threaten a healthy person.
In the hospital, we never take that risk with our most fragile patients. We use sensitive, low-level monitors that catch carbon monoxide long before it reaches that point. TrueDetect is the first detector I've seen built to that same standard for the home.
If you or someone in your home is vulnerable, and you have gas appliances — this is the detector to have on the wall."

Carbon monoxide doesn't build evenly. It concentrates near the source — your gas stove, your water heater, your furnace. And at night, it settles where your family spends the most time: the bedrooms.
Every gas appliance in your home is a potential source. To be fully protected if a leak ever starts, we recommend covering every one of them.
Your gas stove is the single most common source of low-level CO in the home. If a burner ever falls out of alignment or fails to burn cleanly, carbon monoxide can be released just a few feet from where your family eats — which is why it's one of the most important spots to keep protected.
Water heaters run quietly all day, every day. A hairline crack or a partially blocked vent can release CO without any visible sign — and because it runs constantly, year-round, a leak here is just as possible in summer as in winter.
You and your family spend 7–8 hours a night in your bedrooms. If a leak ever starts, this is where the longest exposure would happen — and for anyone vulnerable, it's where protection matters most.
Most families cover the kitchen, the utility area, the bedrooms, and any other rooms with gas appliances nearby. The more units you have, the fewer blind spots in your home — and the more you save per unit.
HVAC technicians, firefighters, and ER doctors — these are the people who see firsthand what carbon monoxide does to a vulnerable body. They know a leak can happen to anyone, in any season, without warning.
So they don't trust the $25 detector at Home Depot to protect the people they love.
They buy the one that catches CO at the low levels that actually matter — built with the same hospital-grade sensors they rely on at work. The one that warns them long before any standard detector ever would.
That's TrueDetect.
"My COPD is finally stable and I intend to keep it that way. When I found out a small leak could undo all of that — and that my old detector would never catch it — I bought three the same day. Now I know if anything ever changes in my air, I'll catch it instantly."
"After my father's stroke, his doctor said another health event could be catastrophic. I wasn't about to let a hidden carbon monoxide leak be the thing that caused it. I put TrueDetects all through his house. Now we both sleep better knowing he's protected."
"My husband has a heart condition, and I learned that carbon monoxide is especially dangerous for people like him — at levels a normal detector ignores completely. I found TrueDetect uses the same sensors hospitals use. We're covered in every room now. Worth every penny for the peace of mind."
"When my mother was diagnosed with early dementia, I read that carbon monoxide exposure can be especially harmful to a brain that's already struggling — at levels a regular detector would never pick up. I wasn't willing to take that risk with her. I put TrueDetects throughout her home. Now if a leak ever starts, we'll catch it immediately, long before it could ever set her back."
"With COPD, you don't get back what you lose. The thought that a tiny leak from an aging water heater could be the thing that puts me on oxygen for good was enough for me. I ordered four. Now my whole home is covered, and I finally feel like I'm one step ahead of this disease instead of waiting for it."
"My mom is 74 and lives alone, and older bodies are far more vulnerable to carbon monoxide than people realize. I didn't want to wait for something to go wrong. I put TrueDetect near her furnace and in her bedroom. Now I know the moment anything changes in her air. Buy this for your parents."
"Once I understood that a leak could happen in any season, from any gas appliance, and that our old detector would stay silent until it was an emergency — I wasn't taking chances. Kitchen, utility room, every bedroom. The more rooms covered, the fewer blind spots. Best money I've spent on our home."
"I feel okay today — but I have a condition that makes me vulnerable, and a leak doesn't announce itself. By the time you'd feel it, the damage is done. TrueDetect means I'll never be caught off guard. I check the number, I know we're safe, and I sleep easier for it."
Plug TrueDetect into any standard wall outlet in your home. No tools. No wiring. No installation. It starts monitoring your air the moment it's powered on.
Look at the display. You'll see the exact carbon monoxide level in that part of your home, updated every second. From that moment on, TrueDetect is watching your air around the clock — so if a leak ever starts, you'll see it immediately, long before it could ever become a danger.
If your reading is ever high, call an HVAC technician — they'll find the source and fix it. And from that day forward, you'll always know the air your family breathes is safe, with a warning that comes early enough to actually matter.
Plug TrueDetect in. Let it start watching your air around the clock.
If a leak ever starts, TrueDetect catches it from as low as 1 PPM — long before it could ever harm the most vulnerable person in your home.
That's protection a standard detector simply can't offer someone who can't afford a leak.
We're so confident in TrueDetect that we're giving you a full 365 days to try it. If for any reason you're not satisfied, contact us for a full refund. No questions asked.
