Hospital-grade carbon monoxide monitoring that shows you the actual PPM in every room of your home — in real time, from 1 PPM — so you always know what your family is breathing.
365-Day 100% Money-Back Guarantee. If for any reason you're not satisfied, you'll get a full refund.
"I'd been waking up with headaches for almost seven months. Doctor visits, bloodwork, a sleep study — every test came back normal. I was told it was probably stress.
The night I plugged TrueDetect in, I saw 17 PPM in my kitchen. 14 PPM in the hallway. I called an HVAC tech the next morning and it turned out our gas stove had a fault I'd never have spotted on my own.
Two days after he fixed it, my headaches were gone. I still can't believe I spent seven months looking for an answer that was in my air the whole time."
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 guessing about what's in your air. You just look at the number. 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.
Standard detectors quietly stop working after 5–7 years and never tell you. Most families have no idea the device on their wall has been dead for years.
TrueDetect lasts up to 10 years — and alerts you before it expires. So you always know it's actively protecting you.
"In 30 years of emergency medicine, I've seen too many families spend months — sometimes years — searching for answers to symptoms that were coming from the air in their own home. Their doctors couldn't find it. Their detectors couldn't see it.
TrueDetect is the first detector built to the standard I actually trust — the same sensor technology we use in the hospital. It shows you exactly what's in your air, in real time.
If you have gas appliances and you care about the health of the people living in your home — 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 actually know what's in your air, we recommend covering every one of them.
Your gas stove is the single most common source of low-level CO in the home. Every time you cook — breakfast, dinner, a late-night snack — CO is being released just a few feet from where your family eats.
Water heaters and furnaces run quietly all day, every day. A hairline crack or a partially blocked vent can release CO continuously without any visible sign. This is where families find the highest readings most often.
You and your family spend 7–8 hours a night in your bedrooms. If CO is building up anywhere in your home, this is where the longest exposure happens — and where it matters most to know.
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 what carbon monoxide actually does to families. They're the ones called when something goes wrong.
And they don't trust the $25 detector at Home Depot to protect the people they love.
They buy the one that shows the actual number. The one built with the same hospital-grade sensors they use on the job. The one that alerts them long before any standard detector ever would.
That's TrueDetect.
"Daily headaches for seven months. Doctor had no answer. Plugged TrueDetect in and saw 19 PPM in my kitchen. Water heater had a cracked vent. Fixed in a day. Haven't had a headache in six weeks."
"Both kids were struggling to focus at school for months. We'd tried everything. Put TrueDetect in their bedroom and it read 16 PPM every night. Gas furnace had a slow fault. A few days after we fixed it they were like different kids. I got my children back."
"Had this persistent cough for a year. Tried every medication. Saw a video about low-level CO and thought why not. Kitchen read 17 PPM. Gas stove had a blocked burner. Three days after the repair, the cough was gone. Still hard to believe."
"Every vacation I felt incredible. Thought it was just stress leaving my body. Came home and felt tired within a day. Plugged TrueDetect in — 18 PPM in my living room. Everything suddenly made sense."
"Plugged the first one into the kitchen — 14 PPM. Water heater — 9. Kids' room — 11. I ordered more that same night. My whole family had been living in this for months. Don't wait on this."
"Three ER trips last year for my daughter's asthma. No medication was working. I plugged TrueDetect in her bedroom and it read 15 PPM every single night. The venting on our water heater was off. Zero attacks since we fixed it."
"My mom is 74 and had been complaining about fatigue and dizziness for two years. Multiple doctors, no clear answer. I put TrueDetect in her house and it read 20 PPM near her old furnace. She feels like a different person now. Buy this for your parents."
"Had brain fog for so long I'd just accepted it as normal. Plugged TrueDetect in and saw 22 PPM in my living room. Called an HVAC tech, got the furnace fixed. I feel sharper than I have in years. This wasn't age. It was my air."
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. If it's low — you have real confirmation. If it's higher than expected — you finally have a clear explanation for the symptoms you've been dealing with.
If your reading is high, call an HVAC technician — they'll find the source and fix it. And from that day forward, you'll always know exactly what your family is breathing.
Plug TrueDetect in. See what's actually in your air.
If the number is high, you'll finally know what's been making everyone feel off. If it's low, you'll have real, measured confirmation that your home is safe.
Either way — you know. And that's the point.
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.

Every day you wait is another day of guessing — when you could be looking at the actual answer on a screen.
Because the detector on their wall was never designed to catch it early. Standard CO alarms are built to a legal minimum, not a safety maximum. They're calibrated to alarm at levels that are already dangerous, which means by the time yours goes off, the exposure has been happening for a while. That's not a flaw in your specific detector. That's how every standard detector on the market was designed to work.
TrueDetect was built around a different standard. One that doesn't wait for danger. One that catches it while you still have time to do something about it.
