Got Air Safe because Contractor used cheapest detectors that wouldn't have caught it until levels were dangerous. New doesn't mean protected.

Is the sensor accurate and dependable?

Yes, Air Safe 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

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.

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.

  • Susan T., Colorado

    We installed AirSafe 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.

  • James Mitchell, HVAC Technician, Illinois

    I'm an HVAC technician with 12 years in the industry. After one bad call, I tested my neighbors' detectors with my professional $400 CO tester. Out of 6 houses, FIVE had detectors that were either dead or wouldn't alarm until you were already dying. I urged each one of them to use the detector I use, which is AirSafe It alarms early when you can still get out safely, shows real CO readings, and monitors the same metrics I check on service calls. I highly recommend this one, even over the “advanced” 200$ ones

  • Jessica L., California

    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.
