$50 AirSafy Gift Card

My daughter had headaches every morning for 5 months. Doctors said allergies.First night with AirSafy: 38 PPM in her bedroom.Our Kidde on the ceiling? Green light, completely silent. Cracked furnace flue. She was being poisoned and our "working" detector never said a word.
-
Replaced a 9-year-old First Alert still showing a green light. Sensor was definitely dead — no way to know. This one shows actual numbers on screen, zero guessing. Display is crisp, alarm is loud. Temp reads about 3°F high but honestly I didn't buy it to check the weather.

Brought it to a cabin rental. First night it caught a propane leak from the wall heater —our two girls were sleeping in the next room. Small enough for a carry-on. We don't travel anywhere without it now.

Does Your Home Have Hidden CO Risk?
(Most American Homes Do)
Use the flexible grid system to create any layout. Each block can be placed in any of the columns.
Do you have an attached garage? Every time you start your car, CO seeps 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, your family is in the danger zone right now.
68% 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 detector sensors expire after 5–7 years but keep showing a green light. So if your detector is older than 7 years, you probably have zero protection right now. Just a plastic box with a light that lies.
This is why 50,000 Americans are hospitalized for CO poisoning every year — despite 90% of homes having detectors.
AirSafy was engineered 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 natural gas and propane leaks, temperature, and humidity fluctuations — the same metrics HVAC professionals use to catch furnace problems before CO even starts building up.
Customer Reviews

James Mitchell, HVAC Technician
"I'm an HVAC tech 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 to use AirSafy. It alarms early, 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."

"We installed AirSafy near our furnace. At 2 AM it started beeping at 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."

Jessica L.
"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."
Professional-Grade Protection Without the Professional Price
AirSafy uses the same electrochemical sensor technology trusted by HVAC professionals and emergency responders — the kind that costs $200+ in commercial-grade detectors. But we made it accessible for every family.
100% Money-Back Guarantee
The "Sleep Safe" 3-Year Promise
Traditional CO detectors don't come with real guarantees because the manufacturers know the sensors expire — and they're counting on you not noticing.
We're so confident in AirSafy that we'll refund your money anytime during the first 3 years if you're not satisfied. AirSafy will last much more than that — up to 6 years. Test it. Trust it. If you don't feel safer, we'll refund every penny. No questions. No hassle.
Frequently Asked Questions
Is this going to go off constantly and drive me crazy?
Is this going to go off constantly and drive me crazy?
No. AirSafy uses professional-grade electrochemical sensors — the same type used in industrial settings. They detect real chemical threats, not toast or shower steam. You'll only hear it when it matters.
Where exactly should I put it?
Where exactly should I put it?
Plug it into any standard wall outlet. Focus on two priorities: near gas appliances (furnace, stove, water heater) and in hallways outside bedrooms. The 3-Pack covers most homes completely.
Why is this more expensive than the $30 detector at Home Depot?
Why is this more expensive than the $30 detector at Home Depot?
Because the $30 detector uses a basic sensor that stays silent at the exact CO levels that cause chronic headaches, brain fog, and fatigue. It's legally allowed to ignore up to 70 PPM for four hours. AirSafy uses the same medical-grade electrochemical sensor found in $400 industrial meters — it shows you every PPM in real time. You're not comparing the same product. You're comparing a nightlight to a diagnostic tool.
Does this detector work for propane?
Does this detector work for propane?
Yes. AirSafy detects propane, natural gas (methane), AND carbon monoxide with separate dedicated sensors. Most store-bought detectors only detect CO. If your stove leaks propane or your furnace line is compromised, those detectors stay completely silent. AirSafy catches all three.
Does it matter how high I install the detector?
Does it matter how high I install the detector?
AirSafy's sensors are calibrated to detect all three gas threats regardless of outlet height. CO mixes evenly with air, so any outlet position works. No ladder needed.
How loud is the alarm? Will it wake you?
How loud is the alarm? Will it wake you?
85+ decibels — louder than a smoke alarm. It comes with 3 adjustable volume levels plus a night mode that dims the display for bedrooms. When danger hits, it WILL wake you up.
Is the sensor accurate and dependable?
Is the sensor accurate and dependable?
AirSafy uses an imported electrochemical sensor with <5 second response time, 0–1000 PPM range, and ±3°F temperature accuracy. These are the same specs used in commercial HVAC diagnostics. The LCD display gives you constant proof the sensor is alive — no more trusting a dead green light.
