I plugged it in to prove she was overreacting. It read 35 PPM. The old detector was still green. Still silent. — David K., Ohio

Americans die from accidental CO every year. Don't become another headline.

ER visits every year tied to accidental carbon monoxide.

No warning
You can't smell it. You can't see it. A green light will not wake you.
Carbon monoxide is the #1 cause of accidental poisoning deaths in the U.S.
Every year, hundreds of American families die from CO poisoning, most of them in heating season. The tragedy almost every time: a working detector on the wall. Green light glowing. Silent. CO comes from furnaces, stoves, dryers, water heaters. You can't smell it. You can't see it.
You just don't wake up.
Every Breath Counts. Cheap detectors wait. HomeHalo doesn't.

I Saw 35 PPM. My Old Detector? Silent.
We had a standard detector for 6 years. Green light. Then I plugged in HomeHalo. 35 PPM in the hallway. The old one was still green. Still silent.

We had a cheap detector in the hallway for years. Green light. Never made a sound. We plugged HomeHalo in on a Saturday and it read 28 PPM next to the furnace. The old one was still green. I don’t guess anymore — I look at the number.

I am not handy. I was sure this would mean a ladder and an electrician. It was a US plug and about 30 seconds. Kitchen outlet, screen showed 000, done. Best money I’ve spent on this house.

I don’t care about gadgets. I care that my daughter is in the next room with the door shut. Cheap alarms wait until 50 PPM. HomeHalo shows me the air while she’s asleep. If that number ever moves, I will know before she feels it.

Frequently Asked Questions
For optimal performance, plug your HomeHalo into a standard wall outlet in a central location of your home. Avoid placing it near windows or doors where airflow might affect its sensors.
No! HomeHalo is completely plug-and-play. Simply plug it into any standard outlet and it's ready to use. No installation, wiring, or electrician needed.
Unlike traditional ceiling smoke detectors that only detect smoke, HomeHalo provides comprehensive protection by monitoring multiple hazards including smoke, carbon monoxide, and air quality in real-time with smart alerts sent directly to your phone.
We recommend one HomeHalo unit per floor for optimal coverage. For a typical 3-bedroom home, 2-3 units should provide complete protection depending on your home's layout.
HomeHalo features a built-in backup battery that keeps it running for up to 24 hours during power outages, ensuring continuous protection when you need it most.
