The Detector HVAC Professionals Recommend

The people who service furnaces for a living see CO leaks every week. They carry professional-grade meters. They know exactly what's in the air of the homes they walk through.

 

They don't use green-light detectors.

"I've been doing HVAC for 14 years. I've walked out of too many houses knowing the family had no idea what they'd been breathing. I have Murabelle in every room of my own home and I recommend it to every customer who'll listen. The number on that screen is the only CO reading I actually trust."

- Gary Hooper., Tennessee HVAC Tech

What Families Found When They Checked

"Our furnace had been leaking since October. Murabelle showed 22 PPM the first morning. Booked a gas company visit that afternoon. Our old detector never moved. My daughter had been complaining of headaches for weeks. Now I know why."

- Ryan S. 

Verified Buyer

"74 years old. Set it up myself in ten minutes without a ladder. My son kept offering to come over and do it for me. I beat him to it. Check the screen every morning. Says zero. That is all I need."

- James D. 

Verified Buyer

"My husband said our detectors were fine. I showed him that the test button only checks the speaker — not the sensor. We ordered the 4-pack that night. He set them all up himself."

- Reylo B. 

Verified Buyer

"Moved into a new house in January. Previous owners had left an old First Alert on the wall. Plugged in the Murabelle next to it on day one. By morning: Murabelle showing 18 PPM. First Alert green and silent. Called the gas company before breakfast."

Frequently Asked Questions

How is this different from the detector I already have?

Standard detectors have a green light that stays on even when CO is building in your home. They don't alarm until 70 PPM — and even then can take up to four hours. Murabelle shows you the exact PPM level on a screen at all times and alarms at 10 PPM. You see what's in your air before it becomes a crisis.

Will it false alarm when I cook?

No. Murabelle uses a professional-grade electrochemical sensor — the same type used by gas company technicians. It detects real CO and gas threats, not cooking fumes or steam.

What gases does it detect?

Murabelle is a 4-in-1 detector. It monitors carbon monoxide, natural gas, and also displays temperature and humidity. Most standard detectors only cover CO. If your stove, water heater, or propane appliance has a leak, a CO-only detector stays silent. Murabelle catches all three.

Where should I place it?

Plug it into an eye-level outlet near each gas appliance and in the hallway outside bedrooms. For most homes the 4-pack covers it: one near the furnace, one in the kitchen, one in the hallway outside bedrooms, one on each additional floor.

How hard is it to install?

Plug it into a standard wall outlet. That is it. 30 seconds. No ladder, no tools, no electrician.

What if my detector is hardwired?

Hardwired means it runs on electricity — but the sensor inside still degrades after 5 to 7 years. The green light stays on even when the sensor is no longer functional. Murabelle shows you a live number so you always know it is working.

How many do I need?

One per floor plus one near any gas appliance. Most homes need four. Apartments typically need two. The 4-pack is the most popular for a reason.

What does the guarantee cover?

Everything. If you are not completely satisfied within 90 days, we refund the full purchase price. No questions. The Lifetime Replacement Warranty covers any defect or malfunction beyond that — we replace it free, for life.
