Does Your Home Have Hidden CO Risk? (Most USA Homes Do)

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.

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 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.

Dewlora 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.

Stories That Started A Movement

⭐⭐⭐⭐⭐ 4.8/5 (6,349 Reviews)

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 $400 CO tester. Out of 6 houses, FIVE had detectors that were either dead or wouldn't alarm until you were already dying. I urged each one of them to use the detector I use, which is Dewlora. It alarms early when you can still get out safely, shows real CO readings, and monitors the same metrics I check on service calls. I highly recommend this one, even over the “advanced” 200$ ones

Susan T., Colorado

We installed Dewlora 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.

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.

Professional-Grade Protection Without The Professional Price

Dewlora 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. The result? A detector that alerts you at 30+ PPM (hours before traditional detectors).

✓ Medical-grade electrochemical sensor – Detects CO as low as 30+ PPM

✓ Triple environmental monitoring – CO, temperature, and humidity

✓ Industrial 5-year lifespan – With daily self-diagnostics

✓ Real-time digital display – Know exactly what you're breathing

✓ Travel-ready – Compact, portable, TSA-approved

Have True Peace Of Mind This Winter

The majority of CO poisoning happens between December and February:
Furnaces running continuously 24/7
Windows sealed shut
Fireplaces and space heaters in constant use
Snow blocking exhaust vents
Cold causing appliance failures
This winter, your detector needs to work 100% of the time.

100% Money Back Guarantee

Traditional CO detectors don't come with guarantees because they expire after a few years and manufacturers know it.

We're so confident in it that we'll refund your money anytime during those 3 years if you're not satisfied. Dewlora 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.

Frequently Asked Questions

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

No. Dewlora 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. Dewlora 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 this detector work for propane?

Yes, our detector does detect propane! However, if propane detection is your main concern, you MUST plug it into a low outlet close to the ground. Propane is heavier than air and sinks, unlike CO which spread evenly throughout your home, so height won't matter for that.

How long does shipping take?

Orders typically take 1 to 2 business days to process. Once shipped, delivery takes around 4 to 8 days depending on your location. You'll receive a tracking number via email as soon as your order is on its way.

Does it matter how high I install the detector?

For carbon monoxide, it won’t matter how high you install it because CO mixes evenly with the air. However, if you’re using it to detect natural gas only (which does not have the same danger of killing you in your sleep like CO, but is mainly a fire/explosion hazard), try to install it as high as possible.

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, Dewlora 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

As a home inspector I get into a lot of homes that do not have a carbon monoxide detectors and the ones that do have no idea how old they are or if they are working. I’m very proud to be partnering with Dewlora 4 in co detectors. Not only are they a great detector they also let the homeowner know it’s time to replace. Safety is my business and I’m proud to offer this to my customers

Like them alot ... i have them in the basement and next to the furnace.

Great product. Display is fantastic

Nice quality and easy to use. Feel safer with CO and gas detectors

I’m really impressed with this 4-in-1 gas and carbon monoxide detector. It’s easy to use—just plug it in—and the digital display is bright and simple to read. I like that it shows temperature and humidity as well, which is a nice extra feature. The alerts are loud enough to hear from another room, and the device feels reliable overall. If you want a detector that gives you quick, clear information and added peace of mind, this one is a great choice
