“I was scrolling at 2 AM while nursing when I saw a video about a family who lost their toddler to CO poisoning. I threw up from anxiety. The next day I found Wardly. The first night I installed it, I slept through until morning for the first time since my son was born. I look at that ‘0’ every single day and exhale. I finally feel like the mom I’m supposed to be.”

Don’t Become Another Headline.
Carbon monoxide is the #1 cause of accidental poisoning deaths in households.
Every year, over 29,000 families die around the world from CO poisoning
Most of them while sleeping. The tragedy? Almost every victim had a “working” detector on their wall. Green light glowing. Silent.
Every winter, it starts the same way:
- The furnace kicks on for the first cold night
- A space heater runs all night in the bedroom
- A generator runs during a winter power outage
Carbon monoxide fills the house. No smell. No color. And the ceiling alarm stays silent.
You just don’t wake up.

“I Saw 47 PPM. My Old Detector? Silent.”
“We had a ‘working’ detector for 6 years. Green light. Beeped when I tested it. Then I got Wardly just to double-check. First night: 47 PPM in my son’s bedroom. My old detector? Still glowing green. Still silent. I unplugged it and threw it in the bin. Wardly probably saved my son’s life.”

“Nan’s House Is Safe Again!”
“When my daughter drops the grandkids off for the weekend, I can honestly say to myself, ‘They are completely safe here.’ I’m the nan, it’s my job to keep this house safe. Wardly gave me back that peace of mind. Nan’s house is officially the safest place on earth again.”

“I Sent One to My Mum”
“I bought one for our house and posted two to my parents. Mum is 74 and lives alone. Her old detector was 12 years old - the sensor was dead but the green light was still on. Now I don’t lie awake at 2 AM wondering if she’s okay. Best decision I ever made.”

Introducing: The Wardly CO & Gas Detector
Wardly is a professional-grade detector specifically designed to show you real-time CO and natural gas levels starting at 0 PPM.
It’s an easy-to-use, accurate device that anyone can install in 30 seconds - no ladder, no tools, no electrician.
Keeping a Wardly in your home is one of the most important decisions you can make for yourself and your family.
Because the silent killer doesn’t give warnings. Wardly does.
Built Different
Built To Protect. Backed for Life.
Most detectors are made cheap with mass produced factory parts because they only have to meet the minimum standard: stay silent until 70 PPM. WARDLY is built with a lab-grade sensor and safety-tested components, because it’s watching over your family.
Lab-grade Sensor
Reads the air 24/7 and alarms at 10 PPM CO, down to the very first trace. Rated for 10 years of service.
Gas + CO In One Plug
Picks up natural gas and propane leaks as well as carbon monoxide, so one unit watches for both silent dangers.
Works Through Blackouts
A built-in rechargeable battery keeps it running 24/7 even when the power goes out, right when generators and space heaters come on and CO risk is highest.
Lifetime Warranty
Covered for as long as you own it, on top of a 90-day money-back trial. If it's not right, we make it right.

“I Bought 8 - One for Each Family Member”
“I kept three for myself and gave one to each of my adult children for their homes. I can’t think of a better gift to give my family - a gift that says ‘I love you and I want you safe’ without saying ‘I’m worried about you.’ I hope they never need it, but if they do, Wardly will be there.”

“My Husband Doesn’t Argue About Safety Anymore”
“My husband said our old detectors were ‘fine.’ Then I showed him that standard US detectors don’t have to alarm below 70 PPM. We ordered Wardly that night. He doesn’t argue about safety anymore.”

“One of the Most Important Things I Own”
“I’m going to be 80 years old and I’ve often thought, ‘what would I do if something happened because I live alone?’ Now I look at that little screen, see ‘0,’ and I know. I’m not alone. Wardly is watching.”

“I am 74 years old and I secured my entire home in under an hour without climbing a dangerous ladder. I just plugged it into the wall socket. I felt so capable and independent. I don’t have to ring my son to come check things for me - I have Wardly telling me I’m perfectly fine.”

“It Caught What Our $200 Nest Missed”
“We had a Nest Protect in every room. Top of the line, right? I bought Wardly just to compare. First week: Wardly showed 29 PPM. The Nest? Silent. Green light. We had a cracked flue on the boiler. Four kids in this house. I don’t even want to think about what could have happened.”

Secure CheckoutQuestions From Homeowners
How is Wardly different from my current detector?
A standard CO alarm shows a green light and stays silent until levels reach around 70 PPM, sometimes for hours. Wardly Detector™ shows you the actual CO level, live, from zero, so you see a problem building long before a standard alarm would make a sound. It also detects natural gas and propane leaks. Keep your existing alarm; Wardly adds the early warning it can't give you.
Will it false alarm when I cook?
Normal cooking won't set it off. It reads carbon monoxide and gas, not smoke or steam. Just keep it a few feet from the stove. Very strong fumes like paint, solvents or cleaning sprays can affect the sensor, so keep it away from those too.
Where should I install Wardly?
Use the manufacturer’s placement guidance for the exact model and any local requirements. Do not choose a location solely because a power outlet is available.
How do I know it's working?
You can see it working: the live number is on the screen every day. You can also run a self-test anytime by pressing the self-test button while it's plugged in. Or test it for real: hold an unlit lighter near the vent in high-sensitivity mode, and the screen turns red within seconds.
Where do I put it? What height?
Plug it into any standard outlet. Outlet height is fine, because CO mixes evenly with the air. Keep it a few feet away from the stove and fireplace, and out of bathrooms and direct sunlight. The screen flips 180°, so it reads right-side up in any outlet.
How many do I need?
One per floor, plus one in or right outside the bedrooms. For a typical two-story home with a basement, that's 4: one in the basement by the furnace and water heater, one on the main floor, and one outside the bedrooms, plus one near an attached garage or gas appliance. Every room with a furnace, water heater or gas stove is a CO source, so the more of them you cover, the earlier you'll know.
Can I use it in a rental or RV?
Yes. There’s nothing to install, so you can take it with you. Just unplug it, pack it, and plug it into any standard outlet when you arrive. That makes it perfect for rentals, hotels, cabins and RVs with shore power.
What if it doesn’t work for me?
Try it for 90 nights. If you're not happy for any reason, send it back for a full refund, and we'll cover return shipping. After that, it's covered by our lifetime warranty. Reach us anytime at hello@trustwardly.com.
My detector is hardwired. Isn’t that better?
Hardwired means it runs on mains electricity, but the sensor inside still expires after 5-7 years. The green light stays on even when the sensor is dead. Wardly plugs in and shows you a real number, so you always know it's working.
What happens if the power goes out?
It keeps running on its built-in rechargeable battery. That matters, because power outages are when people run generators and space heaters, and CO poisonings spike. It recharges automatically when the power comes back.
Why isn't it sold on Amazon?
We sell direct so every Wardly Detector™ ships from fresh stock, straight from us. No resellers, no aged inventory, no knockoffs. Wardly is the only authorized seller.
