Know What's In Your Air. Before It Becomes A Problem.

Haven detects CO and gas from the moment levels start rising — and shows you real numbers on a live display. So you can act early, not after the fact.

Displays CO levels from 30 PPM — while most standard detectors don't react until 70 PPM.

Real-Time PPM Display - Live CO readings on-screen, so you see changes as they happen, not just when an alarm fires.

Triple Gas Detection - Detects natural gas, propane, and LPG - the most common residential gas sources.

"Our old detector showed green for years. This one showed 38 ppm in our basement the first day."

How It Works

Setup takes seconds. Monitoring starts immediately.

1. Plug In

Plug Haven into any standard wall outlet. No wiring, no batteries, no tools required.

2. See Levels

The display immediately shows live CO levels in PPM, gas presence, temperature, and humidity — updated in real time.

3. Stay Informed

If levels rise toward alarm thresholds, Haven's 85 dB alarm activates, giving you time to act before it becomes an emergency.

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 30 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.

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 90-Day Money-Back Guarantee. If you're not satisfied for any reason, we'll replace it for free. No questions. Plus, the Lifetime Guarantee means we replace it free if anything ever goes wrong.
