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 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.

I’m at the part where he explains the green light doesn’t mean the air is safe… I honestly had no idea. Checking every detector in my house tonight.

Jessica
This video made me realize I’ve been trusting one tiny green light way too much:(

Brian
As a former EMT, I can confirm CO calls are terrifying because people usually don’t know anything is wrong until symptoms are already serious! Be aware.

Amanda
The story about the family gave me chills... I always assumed “working detector” meant protected.

Nina
Been using Haven for a month now. Seeing the actual number on the screen is so much more reassuring than just hoping a detector will beep. I feel safe.

Lauren
The part about kids breathing it in while they sleep really got me. Ordered the 4-pack for upstairs, downstairs, kitchen, and furnace room.

Daniel
I had no idea regular detectors could wait hours before sounding. That should be written on the box in huge letters.

Megan
We had a small furnace issue last winter and the detector never made a sound. Watching this makes me wonder how close we actually were...
