Safety isn't something you trust. It's something you see.
Steadfast Haven · The detector firefighters install in their own homes
Haven is for
Parents
Who need to see proof their family is protected — not a green light that might mean nothing.
Homeowners with gas furnaces
Furnaces, water heaters, gas stoves — anything that burns gas can produce CO. Haven watches all of them. Especially through Canada's 6-8 month heating season.
Families done with hope
You've read about what cheap detectors miss. You're here because you want real numbers, not reassurance.

Take your time. Haven will be here when you're ready. But so will the green light.
"I had a 'working' detector for 6 years. Green light. Beeped when I tested it. Haven showed 28 PPM in my son's bedroom. The old detector? Still glowing green. Still silent. Four children in this house."
— Robby M., father of four, Ontario

Haven in your home
Kitchen
Hallway
Near furnace
Living room
Tomorrow morning, you'll walk past the hallway on your way to the kitchen.
You'll glance at the screen. Zero.
You won't stop. You won't think about it. You'll just start your day — knowing that every breath your family takes is clean.
Day one, you'll check it constantly. By the end of the week, it's just part of the hallway. By the end of the month, you won't remember life before it.
That's the difference between hoping you're safe and knowing you are.

You know what that green light means now. Tonight, your family sleeps under your roof. Tomorrow morning, you either see a green light — or a number.
Setup takes 30 seconds
Plug in. See your number. Know.
1
Plug into any outlet
No tools. No electrician. No wiring. Plug it in and it's on. One near the furnace, one per floor, one in the kitchen.
2
See your number instantly
The display lights up with real-time CO and gas readings. You'll see your first number the moment it powers on. Zero means zero.
3
Know your air is safe
If CO reaches 10 PPM — five times earlier than standard detectors — Haven alarms. Loud enough to wake the house. Early enough to act.

Canadian families now see their number every morning
Standard detectors meeting CSA minimum standards stay silent below 70 PPM and can take up to four hours to alarm. Haven shows real-time readings from 0 and alarms at 10 PPM — before symptoms start. The ones at Canadian Tire, Home Depot, and Walmart are all built to this minimum standard.
Plug it into any wall outlet. 30 seconds. No tools, no electrician, no wiring. Standard Canadian 120V plug. You'll see your first reading the moment it turns on.
Haven uses a professional-grade electrochemical sensor — the same type used in fire department equipment. It detects carbon monoxide specifically, not smoke or cooking fumes. Thousands of Canadian families use Haven near gas stoves with zero false alarms.
One per floor plus one near the furnace and any gas appliances. For most Canadian homes, that's 4. A 4-pack covers the whole house.
Orders are processed within 1–2 business days. Free tracked shipping, typically 5–8 business days. You'll receive a tracking number by email as soon as your order ships.
If you don't feel safer the moment you see those numbers, send it back. Any time. Full refund. No questions. Lifetime guarantee.
Yes. Haven is CSA 6.19 Listed — meeting the strictest CO detector standards in Canada. It's independently tested for safety and accuracy. Same sensor technology used by Canadian fire departments.
