Real-time PPM display. Alarms at 10 PPM — seven times earlier than the CSA 6.19 standard. The detector firefighters install in their own homes.
Professional-grade electrochemical sensor — the same type used in industrial CO monitors and by emergency services. Independently tested. Exceeds the CSA 6.19 European standard for residential CO detectors.
What you get:
Plug Haven into any standard Canadian outlet. The display lights up the moment it powers on. You'll see a real number — usually 0 PPM — instead of a green light that might mean nothing. If CO reaches 10 PPM, Haven alarms loud enough to wake the house. No tools. No electrician. No wiring. 30 seconds and you're protected.
Firefighters recommend one per floor, plus one near the furnace and one in the kitchen. Most Canadian homes need 4. Apartments typically need 2. Larger homes or families wanting parents' homes covered often choose 8.
Every Haven comes with our 90-day "Sleep In Peace" money-back guarantee — if you don't feel safer the moment you see those numbers, send it back for a full refund. Plus a lifetime warranty on the device. If anything ever goes wrong, we replace it free.

Verified Canadian families who replaced their silent detectors
I was up at 2 AM feeding the baby when I saw a video about a family who lost their toddler to CO poisoning. I felt physically sick. The next day I found Haven. 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.
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 put it in the bin. Haven probably saved my son's life.
I bought one for our house and sent two to my parents. Mom is 74 and lives on her own. 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.
My husband said our old detectors were 'fine.' Then I showed him that 40% of detectors fail to alarm at dangerous levels. We ordered Haven that night. He doesn't argue about safety anymore. The display is the proof.
I am 74 years old and I secured my entire home in under an hour. No ladder. No electrician. Just plugged them in. I felt so capable and independent. I don't have to ring my son to come check things for me — I have Haven telling me I'm perfectly fine.
We had a Nest Protect in every room. Top of the line. 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.
I install furnaces for a living. I see failures every week. Cracked heat exchangers. Blocked flues. Hardwired detectors that haven't worked for years. The green-light-only ones are the worst — homeowners think they're safe and they're not. Haven shows the actual number. It's the only detector in my own house.
Carbon monoxide is one of Canada's leading accidental poisoning death — approximately 50 Canadian families bury someone every year, and over 1,000 are rushed to ER. Most of them had a "working" detector on the wall. Green light glowing. Silent.
Haven shows real-time PPM levels on a digital display and alarms at 10 PPM — seven times earlier than the CSA 6.19 standard. You see the truth, not a light that lies.
Inside every Haven is the same type of professional-grade electrochemical sensor used in industrial CO monitors and by emergency services. It detects carbon monoxide, natural gas, and propane in real time — with PPM readings on the display starting at 0.
Independently tested. Exceeds the CSA 6.19 European standard. No false alarms from cooking, steam, or aerosols. 7+ year sensor lifespan with no batteries to replace.
CSA 6.19 was written in 1999 and hasn't been meaningfully updated in over 25 years. Cheap detectors built to its minimum can stay silent below 70 PPM and take up to 4 hours to alarm above it — by then, your family has already been breathing poison.
Haven exceeds the standard. Real-time display from 0 PPM. Alarm at 10 PPM. The detector firefighters wish every home had.
Try Steadfast Haven completely risk-free for 90 days. If you don't feel safer the moment you see those numbers, send it back. Full refund. No questions. Plus a lifetime warranty on the device — if anything ever goes wrong, we replace it free. The only risk left is the one in your hallway right now.

We believe in full transparency. Here are the answers to the questions families ask most before they switch.
Most detectors meet the CSA 6.19 minimum — they stay silent below 70 PPM and can take up to 4 hours to alarm above it. Haven shows real-time PPM readings from 0 upward, and alarms at 10 PPM — seven times earlier — before symptoms start. You see the actual number, not a green light that might mean nothing.
CSA 6.19 was written in 1999. Standards bodies move slowly. Manufacturers prefer cheap-to-build detectors that meet the minimum. Retailers want inventory they can sell at low margins. Nobody in the chain benefits from a stricter standard — so nobody pushes for one. That's why families have to take matters into their own hands.
No. Haven uses a professional-grade electrochemical sensor — the same type used in industrial CO monitors. It detects carbon monoxide and gas specifically, not toast, steam, aerosols, or cooking fumes. Thousands of Canadian families use Haven in kitchens with gas stoves and zero false alarms.
Haven is a 4-in-1 detector. It monitors carbon monoxide, natural gas, AND propane, plus temperature and humidity. Most cheap detectors from the high street only detect CO. If your stove leaks natural gas, your furnace has a fault, 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.
Haven plugs into any standard Canadian 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 threats regardless of socket height. Most families start with one near the furnace, one in the kitchen, and one in the hallway outside bedrooms. The 4-pack covers most homes completely.
One per floor + near bedrooms + near gas appliances (furnace, water heater, kitchen). Most homes need 4. Apartments typically need 2. Larger homes or families covering parents' homes often choose 8.
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. Haven plugs in and shows you a real number, so you always know it's actually working.
Yes. Haven is perfect for people who live on their own. It watches 24/7 and will alert you to danger even while you're sleeping. Many of our customers are older people who live independently and wanted peace of mind. The display lets you see at a glance that everything is fine — no second-guessing a green light.
Orders are dispatched within 1-2 business days from our Canadian warehouse. Canada Post tracked delivery to most Canadian addresses takes 3-7 business days.
You're covered by our 90-Day "Sleep In Peace" Guarantee. If you're not satisfied for any reason, we'll refund every penny. No questions. Plus the Lifetime Warranty means we replace it free if anything ever goes wrong. Zero risk.
