Does Your Home Have Hidden CO Risk?

Answer these questions:

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're at risk. If you answered yes to TWO or more, you're in the danger zone.

57% of CO Poisoning Victims Had "Working" Detectors That Never Went Off. Don't Let This Be Your Family.

Traditional CO detectors are designed to only alarm at near-fatal levels (70-150 PPM). By the time they sound, you've already been breathing poison for hours.

Even worse? Most detectors expire after 5-7 years but keep showing a green light. So if your house is older than 7 years you probably have zero protection right now.

This is why 50,000 Americans are hospitalized for CO poisoning every year... despite 90% of homes having detectors.

Lunqia TrueDetect was designed to solve this exact problem. Instead of waiting until CO reaches dangerous levels, it alerts you at 30+ PPM - giving you hours to evacuate before anyone gets sick. It also monitors temperature and humidity fluctuations (the same metrics HVAC professionals use) 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 $400 CO tester. Out of 6 houses, FIVE had detectors that were either dead or wouldn't alarm until you were already dying. I urged each one of them to use the detector I use, which is Lunqia's TrueDetect. It alarms early when you can still get out safely, shows real CO readings, and monitors the same metrics I check on service calls. I highly recommend this one, even over the “advanced” 200$ one

We installed Lunqia's TrueDetect near our furnace. 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, we might not have woken up. Since then I've become that person who won't shut up about CO detectors. My neighbors get annoyed when I bring it up. I don't care. I just can't wrap my head around risking your family's life over a few bucks.

Our CO detector was installed in 2011. Fourteen years with a green light, and I never questioned it. We had three kids sleeping under that useless piece of plastic every night. I'll drop $80 on takeout without thinking twice, but I was gambling with my kids' lives to save a hundred bucks. I was stupid. If you haven't replaced yours in the last 5-7 years, do it.

Frequently Asked Questions

Is this going to go off constantly and drive me crazy?

No. Lunqia TrueDetect uses intelligent algorithms to tell the difference between harmless CO spikes (like briefly running your gas stove) and dangerous CO buildup (like a cracked furnace leaking gas for hours). You'll only get alerts for actual threats, not normal everyday activity.

Where exactly should I put it?

Put one within 15 feet of bedrooms (CO poisoning happens most at night while you're sleeping), one near your furnace or main living area, and one on each floor of your home. If you have a fireplace or attached garage, place one nearby. The portable design means you can move it anywhere easily.

Why is this more expensive than the $30 detector at Home Depot?

That $30 detector only alarms at 70-150 PPM—when you're already poisoned and potentially unconscious. It also expires after 5-7 years without telling you, so you have no idea if it's even working. TrueDetect alerts at 30+ PPM (giving you hours to escape instead of minutes), lasts 10 years, shows real-time readings, and actually tells you when it's time to replace it. The question isn't "why spend $60?"—it's "why risk your family's life to save $30?"

Does it work during power outages?

Yes. Lunqia TrueDetect has built-in battery backup that automatically kicks in when the power goes out—which is exactly when furnaces and heating systems are most likely to malfunction and leak CO. Your protection never stops.

Can I take this when I travel?

Absolutely. Lunqia TrueDetect weighs just 8 ounces, fits in any carry-on bag, and works in any standard outlet. This is perfect for hotels (which often have expired or no detectors), Airbnbs (where the owner installed the cheapest detector possible), and RVs (where propane appliances produce CO in tight spaces). Your protection goes wherever you go.

How hard is it to install?

It takes 3 seconds. Just plug it into any standard outlet. No electrician, no drilling, no tools, no wiring. That's it.

How loud is the alarm? Will it wake you?

The alarm is rated at 85 dB, which is as loud as a blender or city traffic. It's designed to be heard even through deep sleep so you can act immediately.

Is the sensor accurate and dependable?

Yes, Lunqia TrueDetect uses a professional-grade electrochemical sensor, the same technology trusted by safety professionals. It's far more reliable than low-cost semiconductor sensors found in cheaper models
