“I’d been anxious about home safety since my son was born. I started researching CO detectors and kept seeing that standard ones don’t show actual readings. When I found Haven I decided to try it. The first night, I could actually see the 0 on the screen, real confirmation, not just a light. I check it every day now. It genuinely gave me a peace of mind I didn’t have before.” — Sarah M., Texas

Most Families Don’t Know What’s Actually In Their Air.
According to the CDC, carbon monoxide is the leading cause of accidental poisoning deaths in the U.S., with more than 400 deaths and 100,000 emergency room visits annually.
What surprises most families: the majority of these incidents happen during sleep — often in homes where a detector was installed and showing a green light.CO is invisible and odorless. It comes from furnaces, water heaters, garages, and stoves. Standard detectors don’t show you levels, they only alarm once a threshold is crossed.
Haven shows you what’s in the air in real time.
Real-Time Awareness. Standard detectors wait for a threshold. Haven monitors from the start.

“Haven Showed 47 PPM. My Old Detector Showed Nothing.”
"We had a 'working' detector for 6 years. Green light. Beeped when I tested it. Then I got Haven 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 trash. Haven probably saved my son's life."

“Grandmas House is Safe Again!”
"When my daughter drops the grandbabies off for the weekend, I can honestly say to myself, 'They are completely safe here.' I am the matriarch — it's my job to provide a safe haven. Haven gave me back that peace of mind. Grandma's house is officially the safest place on earth again."

"I Sent One to My Parents"
"I bought one for our house and sent two to my parents. Mom 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."

"I Bought 5 — One for Each Family Member"
"I kept one 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, Haven will be there."

"My Husband Doesn't Argue About Safety Anymore"
"My husband said our old detectors were ‘fine.’ Then I showed him the research on standard alarm thresholds, and how long exposure can occur before an alarm triggers. We ordered Haven that night. He doesn’t question it anymore."

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

Questions from Homeowners
How is Haven different from my current detector?
Most detectors only show a green light, which can remain lit even as the sensor ages past its reliable lifespan. They don’t alarm until 70 PPM, which is after potential lower-level exposure has already accumulated. Haven shows real-time levels from 0 PPM on a digital display, an actual number, not a status indicator.
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 4-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 4. 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.
