Our furnace guy checked our 8-year-old detector. Still green, basically useless. We replaced it and now see a real number. hoping that means our kids are safe.
Does Your Home Silently Expose Your Family to CO Risk?
Take this 60-second assessment:
Do you have an attached garage?
+
Every time you start your car, CO can seep through shared walls—even when the garage door is open.
Is your home older than 15 years?
+
Furnace heat exchangers develop cracks over time. Small cracks leak CO for months before causing complete failure.
Do you use natural gas, propane, or oil heat?
+
Any fuel-burning system produces CO. One blocked vent, one malfunction, one crack—and it's in your air.
Do you have a fireplace or wood stove?
+
Creosote buildup, blocked chimneys, and downdrafts push CO back into your home instead of up and out.
If you answered yes to even ONE of these, you have confirmed exposure pathways.
If you answered yes to TWO or more, you're living in the chronic exposure zone.
57% of CO Poisoning Victims Had "Working" Detectors That Never Went Off.
Traditional CO detectors only alarm at near-fatal levels (70-150 PPM). By the time they sound, you've been breathing poison for hours.
That why 50,000+ Americans are hospitalized for CO poisoning every single year...
Despite 90% of homes having detectors
SafeGuard alerts you at 30+ PPM—giving you hours to evacuate before anyone gets sick. It monitors temperature and humidity fluctuations to catch furnace problems before CO even starts building up.

I'm an HVAC technician with 35 years in the industry. After one bad call, I tested my neighbors' detectors with my professional meter out of 6 houses, 5 had detectors that were either dead or wouldn't alarm until lethal levels. I told them all to get SafeGuard because it alarms early at safe levels, shows real PPM readings, and monitors the same metrics I check on service calls.

We installed SafeGuard near our furnace and at 2 AM it started beeping 45 PPM. Fire department found a cracked heat exchanger. Our old detector? Still silent. The firefighter said if we'd waited for that one to go off, we might not have woken up.

I travel for work almost every week, and hotels don't always have CO detectors. This is the first thing I plug in when I check in. Gives me peace of mind knowing I can actually see what's in the air.

Questions? We’ve Got You Covered
Will this go off constantly and become annoying?
+
No. SafeGuard™ is designed to distinguish between brief, harmless CO fluctuations (like momentary stove use) and sustained CO buildup. You’ll only receive alerts when levels reach a threshold that requires attention — not during normal everyday activity.
Where should I place it?
+
For best protection, place one unit within 10–15 feet of bedrooms, one near your main living area or furnace, and one on each level of your home. If you have an attached garage or fireplace, placing a unit nearby is recommended. The plug-in design allows you to reposition it easily.
Why is this more expensive than basic detectors?
+
Many basic detectors only sound alarms at higher CO concentrations and do not display real-time readings. SafeGuard™ provides continuous monitoring with a digital PPM display and early alert threshold at 30+ PPM, along with a longer sensor lifespan and built-in sensor replacement reminder.
It’s not just an alarm — it’s a monitoring device.
What is your return policy?
+
We offer a 30-day return policy. If you're not satisfied with your purchase, you can return it within 30 days for a full refund or exchange.
Does it work during power outages?
+
Yes. SafeGuard™ includes built-in battery backup that automatically activates during power loss, so monitoring continues uninterrupted.
Can I use it while traveling?
+
Yes. SafeGuard™ is compact and lightweight, making it suitable for hotels, rental properties, RVs, and other temporary stays. Simply plug it into any standard outlet.
How do I install it?
+
Installation takes seconds. Just plug it into a standard wall outlet. No tools, wiring, or professional installation required.
How loud is the alarm?
+
The alarm is rated at 85 dB, loud enough to alert occupants during sleep or from another room.
Is the sensor accurate and dependable?
+
SafeGuard™ uses an electrochemical CO sensor — the same sensing technology widely used in professional safety equipment — for stable and reliable detection over time.
