Carbon monoxide is the #1 cause of accidental poisoning deaths in America.

Every year, over 400 Americans die from CO poisoning most of them while sleeping. The tragedy? Almost every victim had a "working" detector on their wall. Green light glowing. Silent.

CO comes from furnaces, water heaters, garages, stoves. You can't smell it. You can't see it.

You just don't wake up.

Every Breath Counts.Cheap detectors wait. Haven doesn't.

Introducing: The Haven CO & Gas Detector

Haven is a professional-grade detector specifically designed to show you real-time CO, natural gas, and propane 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 Haven 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. Haven does

Designed By Firefighters. Built To Save Lives.

Haven was developed with first responders who saw the same tragedy repeat itself — families with "working" detectors who never got the warning they deserved.

✓ UL 2034 Certified — Strictest CO detector standards in North America
✓ Professional-Grade Sensors — Same technology used by fire departments

✓ ETL Listed — Independently tested for safety and accuracy

Haven isn't just another detector. It's the detector firefighters wish every home had.
Like having a fire station in your hallway — watching the air so you don't have to.

What Makes Haven So Different

  • "Right Now, While You Read This"

    Right now, a family is breathing poison. Detector glowing green. Kids asleep. No idea.

    Some will wake up with headaches. Some won't wake up at all.

    This isn't a someday problem. It's a tonight problem.

    Do you know your detector works or are you just hoping?


    Hope isn't protection. Haven is.

    "I built Haven after my daughter's close call. No family should trust a green light that lies." — James Chen, Founder

I Bought 5 — One for Each Family Member

After losing my home to a fire years ago, I don't take safety lightly. When I heard about Haven's 4-in-1 detector, I knew I had to get one for everyone in my family. The peace of mind knowing they're protected from smoke, carbon monoxide, natural gas, and propane is priceless. Setup was incredibly easy, and the app notifications give me real-time updates. This is the kind of product that saves lives.

Best Investment for Home Safety

As a mother of three, safety is my top priority. The Haven detector has given me incredible peace of mind. Last week, it detected a small gas leak that our old detector completely missed. The instant alert on my phone allowed me to act immediately. I can't imagine going back to traditional detectors. This is truly a life-saving device.

Finally, a Detector That Actually Works

I've tried multiple detectors over the years, and most of them were either too sensitive or not sensitive enough. Haven strikes the perfect balance. The 4-in-1 protection means I don't need multiple devices cluttering my ceiling. The smart features are intuitive, and I love being able to check the status from anywhere. Highly recommend to anyone serious about home safety.

Questions from Homeowners

How is Haven different from my current detector?

Most detectors only show a green light — which stays on even when the sensor is dead. They don't alarm until 70 PPM, which is AFTER 1-4 hours of exposure. Haven shows you real-time levels from 0 PPM on a digital display. You see the truth, not a light that lies.

Will it false alarm when I cook?

No. Haven uses professional-grade electrochemical sensors — the same type used in industrial settings. They detect real threats, not toast or shower steam.

Does Haven detect propane and natural gas, or just carbon monoxide?

Haven is a 4-in-1 detector. It monitors carbon monoxide, natural gas, AND propane, plus temperature and humidity. This is a critical distinction. Most cheap detectors from the hardware store only detect CO. If your stove leaks natural gas, your furnace has a propane leak, or your water heater line is compromised, those detectors stay completely silent. Haven catches all three gas threats in real-time, with PPM readings on the display starting at 0. One unit. Complete protection. No gaps.

Where should I install Haven? Does height or outlet position matter?

Haven plugs into any standard wall outlet, no ladder, no tools, no electrician. 30 seconds and you're protected. For placement, focus on two priorities: near gas appliances (furnaces, stoves, water heaters) and in hallways outside bedrooms where your family sleeps. Haven's sensors are calibrated to detect all three regardless of outlet height. Most families start with one near the furnace/water heater, one in the kitchen near the stove, and one in the hallway outside bedrooms. The 3-Pack covers most homes completely.

Is it hard to install?

No. Plug it into any eye-level outlet. That's it. Takes 30 seconds. No ladder, no tools, no electrician.

How many do I need?

One per floor + near bedrooms + near gas appliances (furnace, water heater, garage). Most homes need 3. Apartments typically need 2.

Can I use it if I live alone?

Yes! Haven is perfect for people who live alone. It watches 24/7 and will alert you to danger even while you're sleeping. Many of our customers are seniors who live independently and wanted peace of mind.

What if it doesn't work for me?

You're covered by our 100-Day "Sleep in Peace" Guarantee. If you're not satisfied for any reason, we'll refund every penny. No questions. Plus, the Lifetime Guarantee means we replace it free if anything ever goes wrong.

My detector is hardwired. Isn't that better?

Hardwired means it runs on electricity — but the SENSOR inside still expires after 5-7 years. The green light stays on even when the sensor is dead. Haven plugs in and shows you a real number, so you always know it's working.

How fast will I receive it?

Ships from US warehouse. 3-5 business days typically.

What if it doesn't work?

90 days. Full refund. Keep everything. Zero risk.
