Never thought about CO until a friend had a scare. Plugged this in, saw the zero on the screen and felt better instantly. It just sits there and does its job.

Carbon Monoxide Is the
#1 Cause of
Accidental Poisoning Deaths in America.
Every Year, 400+ Americans Go To Sleep And Never Wake Up
Don't Let Your Family Become A Statistic
Most families assume they're protected.
They're not.
CO has no smell. No color. No taste. It silently fills your home while you sleep. Your furnace kicks on in the middle of the night. A small leak. Nothing dramatic. No explosion. No fire. Just gas, slowly building in the air your family is breathing.
But you're asleep. You feel nothing. By morning, your family doesn't wake up.
100,000+
ER visits/year due to CO exposure
400+
Accidental Deaths per year due to CO exposure
84%
of fatal CO incidents occur from September to April.
No Warning
Many detectors can stay silent during long exposure to low or mid-level carbon monoxide, even though those levels can still cause serious health problems or death.

Every Second Counts: Protect Your Family
From Deadly Gas Leaks and Fires
Real-Time Monitoring for Carbon Monoxide, Propane, Natural Gas, and Smoke.
Real-Time Readings, 24/7
Do you know what quality of air your family is breathing right now? Most detectors stay silent until CO hits 70 Parts Per Million (PPM). By then you've been breathing it for hours.
The CarbonOne Safe monitors from 0 PPM and shows you live CO and gas levels every second of every day. Not a green light. Not a guess. A real number, in real time, so you always know your family is safe.
"I look at that screen every morning before I make coffee.
Seeing '0' every day has completely changed how I feel in my own home."— Michelle R., Ohio
4 in 1 Protection
Most detectors only watch for one danger. CarbonOne Safe gives your home 4-in-1 protection by monitoring carbon monoxide, natural gas, propane, and smoke from fire in one device. With clear real-time readings and instant alerts, you can spot danger early and act fast.
“I bought CarbonOne Safe for CO protection, but it ended up alerting us to a kitchen fire. A pan started smoking while we were in the other room, and the alarm went off before we noticed. We got there fast and stopped it before it got serious.”
— Chris K., Minnesota
Instant Alert
When danger hits, seconds matter. The CarbonOne Safe sounds an immediate alarm alerting your family that CO, gas or smoke has been detected, cutting through sleep and noise No confusion. Just fast, clear action when it counts most.
"My daughter is 7. She heard the alarm during our test and knew exactly what to do. That alone was worth every penny."
— David T., Georgia
5 Second Setup
No ladder. No tools. No electrician. Plug the CarbonOne Safe devices into any standard outlet and your family is fully protected.
"I'm 71 years old and set it up myself. Didn't need to call my son for help for once. That felt pretty good."— Barbara K., Florida
Battery Backup Protection
Power outages don't pause gas leaks or fires. The CarbonOne Safe keeps monitoring your home even when the lights go out, because the moments you're most vulnerable are exactly when you need it most.
"We lost power during a storm last winter. First thing my husband said was 'at least the CarbonOne Safe is still running.' That's when I knew we made the right call." — Sandra M., Michigan
Always On, Always Working
Most detectors fail silently. The green light stays on long after the sensor dies and you'd never know. The CarbonOne Safe continuously runs self-checks so you never have to wonder if it's working. It always is.
"I thought we were safe because our detector never went off, but an annual HVAC inspection found a dangerous leak our 'working' alarm completely missed. Now I realize I had no idea if it even worked. Never making that mistake again."— James L., Texas

Plugged it in and it was up and running. Love that you can actually see the numbers on the screen. Our old one just had a green light. Highly recommend.

Doesn’t just cover CO but gas as well which most cheap ones don't. Screen is clear, setup took no time. Great price considering everything it covers. Would buy again.

I'm not tech savvy at all and had zero issues setting this up. Just plugged it in. Screen came on. Done. My daughter kept telling me to get one and I’m glad she did.

Was looking for something simple that just works. This is it. Screen shows you the levels, alarm goes off if something is wrong. No complaints. Fast shipping too.

She's older and lives alone. Wanted something easy for her to use. She had it set up herself in under a minute. Simple and gives us both peace of mind.

Spent way too long relying on an old detector with a green light. This actually shows you what's in the air. Should have switched sooner. Already ordered another one for upstairs.

Got this after a neighbor mentioned their old detector had failed without them knowing. Setup took less than a minute. Covers CO and gas which I didn't realize most detectors don't. Really glad I got it.

Frequently Asked
Questions
It detects carbon monoxide, natural gas, and propane. Most cheap detectors only cover CO. This one covers all three.
Plug it into any standard wall outlet. That's it. No tools, no ladder, no electrician. Takes 5 seconds.
It shows you the live CO level in your home at all times. Zero means your air is clean. The higher the number the more CO is present. If levels get dangerous the alarm goes off automatically.
Most standard detectors just show a green light and don't alarm until CO hits 70 PPM. By then you've already been breathing it for hours. The CarbonOne Safe shows you real numbers starting at 0 PPM so you see danger rising before it becomes an emergency.
The built-in battery backup keeps it running even when the power goes out.
It runs automatic self-checks continuously. You don't have to do anything. If something is wrong it will tell you.
The CarbonOne Safe is rated for 5 years. Most cheap detectors burn out in 2 to 3 years while the green light keeps glowing like nothing is wrong.
Near gas appliances like your furnace, water heater or stove, and in the hallway outside bedrooms. Most homes are fully covered with 2 to 4 units.
One per floor is a good starting point. Add one near any gas appliance and one outside each sleeping area for full coverage. Most families need 2 to 4.
