37,000 Families Upgraded Their CO Protection This Year — Here's Why Yours Might Need It Too

By Jessica M.

Last Updated Dec 3.2025

Summary: Most people assume they're protected from carbon monoxide — but the detector on your wall may be giving you a false sense of security. Whether you have one or not, there's a reason 37,000 families upgraded their CO protection this year. Discover the seven things about your home's safety that might surprise you.

1. Your Detector Might Not React Until It's Already Too Late

Most CO detectors sold at hardware stores are built to the UL 2034 standard — which means they're legally allowed to stay silent until carbon monoxide levels hit 70 parts per million. At that level, you're not being warned before danger. You're already in it.

 

SignalSafe shows you real-time CO levels on its display — so you can see exactly what's in your air at 25ppm, nearly 3x before a standard detector would ever react.

2. Your Smoke Detector Can't See Carbon Monoxide 

This is one of the most dangerous assumptions in home safety. Smoke detectors detect smoke — not carbon monoxide. They are two completely different gases requiring two completely different sensors.

 

Yet millions of families sleep at night thinking their smoke detector has them covered for both. If you don't have a dedicated CO detector in your home, you have zero visibility into one of the leading causes of accidental poisoning deaths in the US.

3.Your Detector Has an Expiration Date — And It Probably Already Passed

Most people don't know that CO sensors naturally degrade over time. After 5–7 years, the electrochemical sensor inside your detector quietly stops working — no alert, no warning, no indication anything is wrong. It just sits on your wall looking like it's doing its job while doing nothing at all.

 

The average American hasn't thought about their CO detector since they installed it. If you can't remember when you got yours, there's a real chance it's already expired.

 

SignalSafe plugs directly into any outlet and displays your current CO levels in real time — so you always know your protection is active, accurate, and working right now.

4. Low-Level CO Exposure Has No Alarm — But It's Still Damaging Your Health

Most people think of carbon monoxide as an all-or-nothing threat — either the alarm goes off or you're fine. But that's not how CO works. Prolonged exposure to low levels can cause chronic headaches, fatigue, and dizziness that most people chalk up to stress or poor sleep. Many never connect the dots.

 

Standard detectors only alarm at dangerous levels. Anything below that threshold goes completely undetected — for days, weeks, or even months at a time.

 

SignalSafe's real-time display shows you exactly what's in your air at all times — so you can spot low-level exposure before it becomes a long-term problem.

5. Away From Home Doesn't Mean Away From Danger

When you leave your home, your CO protection stays behind. Hotels, Airbnbs, and vacation rentals are not required to have CO detectors in every room — and many don't have them at all. You have no way of knowing what's in the air of a room you've never been in, with appliances you've never used, in a building whose maintenance history you know nothing about.

 

CO poisoning in rental properties happens every year — to families on vacation, on work trips, and weekend getaways who thought they were safe because they were only staying a few nights.

SignalSafe is small enough to pack in your bag and plugs into any standard outlet — so your protection travels with you wherever you go.

6. Your Home Is Full of CO Sources — And Most People Can't Name One

Carbon monoxide isn't some rare industrial hazard. It's produced by almost every fuel-burning appliance in your home — your furnace, your water heater, your gas stove, your fireplace, and your attached garage. Any one of them can develop a leak, a blockage, or a malfunction that starts quietly filling your home with CO.

 

Most homeowners couldn't name a single source without thinking hard about it. And that's exactly the problem. You can't protect yourself from something you don't know is there.

 

SignalSafe gives you a live reading of your home's CO levels at all times — so no matter which appliance is the source, you'll see it the moment it starts.

7. Why 37,000 Families Upgraded Their CO Protection This Year

After learning what standard detectors can and can't do, the decision becomes pretty simple. 37,000 families this year decided that a device that only reacts when danger is already critical — or worse, no device at all — wasn't good enough for the people they care about most.

 

SignalSafe was built for exactly that moment. A real-time display that shows you live CO levels in your home, displays at 25ppm before symptoms begin, and travels with you beyond your front door. No expiration surprises. No false sense of security. Just clear, visible protection you can see working every single day.

 

If any of the last seven points made you think twice about your home's protection — that's exactly why we built this.
