Frequently Asked Questions

Standard detectors stay silent below 50–70 PPM and can take up to 4 hours to alarm. Haven shows real-time readings from 0 and alarms at 10 PPM — before symptoms start. The detectors at Canadian Tire, Home Depot, Walmart, and most retail stores are all built to minimum safety standards, not to protect you early.

Plug it into any wall outlet. 30 seconds. No tools, no electrician, no wiring. 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 families use Haven near gas stoves with zero false alarms.

One per floor plus one near the furnace or boiler and any gas appliances. For most homes, that's 4. A 4-pack covers the whole house.

Yes. Haven has dual sensors — one for carbon monoxide and one for combustible gases including natural gas and propane. Standard detectors only detect CO.

Haven is EN 50291 certified (UK/EU) and CSA 6.19 Listed (Canada). It's independently tested for safety and accuracy, using the same professional-grade electrochemical sensor technology found in fire department equipment.

Especially if you live alone. CO poisoning symptoms mimic flu and exhaustion. Without someone else to notice, you might not realize what's happening until it's too late. Haven's alarm at 10 PPM gives you early warning when there's no one else to sound it.

Hardwired detectors use the same basic sensors as plug-in models — they just get power from your home's wiring instead of an outlet. The issue isn't how it's powered. It's what it detects and when it alarms. If your hardwired detector stays silent below 70 PPM with no digital display, it has the same blind spot as every other standard detector. Haven plugs into any outlet and gives you real-time numbers from 0 PPM.
