What happens after I plug it in?
What happens after I plug it in?
Plug into any outlet. Within 60 seconds, Cremores starts monitoring. No app, no Wi-Fi, no batteries needed. CO spreads evenly through air, so placement height doesn't matter — any room, any outlet.
How many units does my home need?
How many units does my home need?
Most homes need 3–4 units. One near bedrooms, one in the kitchen, one near your furnace or water heater, and one per additional floor. Cover where you sleep, cook, and run gas appliances.
How is this different from a standard detector?
How is this different from a standard detector?
Standard detectors show a green light. Cremores shows real numbers.
Standard detectors alarm at 70 PPM. Cremores alarms before 30 PPM.
Standard detectors only see carbon monoxide. Cremores sees carbon monoxide, natural gas, and propane.
Standard detectors use cheap grade 1 sensors. Cremores uses grade 3 sensors — faster, more accurate, longer lasting.
Standard detectors make you guess. Cremores lets you know.
How do I read the numbers on screen?
How do I read the numbers on screen?
- PPM — The amount of carbon monoxide in your air. Zero means clean air. The higher the number, the more CO is present. Cremores alarms before 30 PPM.
- GAS LEL — The percentage of natural gas or propane in your air. Zero means no leak. Any number above zero means gas is leaking somewhere. Act immediately.
- Humidity — The moisture level in your home. Shown as a percentage. Normal is between 30–50%. Helps you keep your air comfortable and healthy.
All three. One screen. Real numbers. No guessing.

Your Current Detector May Not Be Enough
Most households rely on a device that only confirms it's powered — not that the air is safe. Cremores shows you exactly what's in your air, in real time.
Don't Trust Silence
A green light doesn't mean clean air. CO builds quietly — and by the time most detectors react, the risk is already real.
DEATHS ANNUALLY
From accidental CO exposure at home
EMERGENCY VISITS
Caused by CO poisoning each year
Cremores Helps Stop The Danger
Cremores doesn't wait until it's dangerous to warn you. It alarms early — giving your family time to act before a late alarm becomes the first sign of trouble.
What CO does to your body — Before you even know it's there
Carbon monoxide is invisible and odorless. Symptoms start well before most detectors make a sound.
Cremores displays live PPM so you can see CO levels rising — not wait for a threshold alarm that may already be too late.
Most detectors only catch carbon monoxide. Cremores also detects natural gas and propane — three risks, one device.
Cremores alerts from 30 PPM. That gap between 30 and 70 PPM is the window that keeps your family safe.
Helps Protect Your Family Earlier
Standard detectors stay silent until 70 PPM. Cremores warns you at 30 PPM — giving your family time to act before symptoms start.

"Earlier visibility and broader detection make Cremores a fundamentally more reliable safety tool." — Firefighter & HVAC Professional
Designed By People Who've Seen What Happens When Detectors Fail
Cremores was built with first responders who watched the same pattern repeat — families with "working" detectors who never got the warning they deserved.
✓ UL 2034 Certified — strictest CO detector standards in North America.
✓ Professional-grade sensors — the same technology used in the field.
✓ ETL Listed — independently tested for safety and accuracy.

Trusted by 10,000+ Households
"Got 4 for myself, then 4 more for my daughter. Those old green-light detectors are gone for good. My grandkids deserve real protection — not a blinking light."
"I respond to CO calls for a living. I've walked into homes where the detector light was still green while families were at risk. Cremores is the only one I trust at home."
"We live in our RV 100+ nights a year. Switched to Cremores and now I actually know what we're breathing. In a small space, real numbers matter more than a green light ever could."
YOU GOT QUESTIONS
We Got Answers
Does it detect gas and propane, or just CO?
Does it detect gas and propane, or just CO?
All three — one device. Cremores simultaneously monitors carbon monoxide, natural gas, and propane. Most standard detectors only catch CO, leaving natural gas and propane leaks completely invisible. With Cremores, all three threats are covered on a single screen.
How many do I need?
How many do I need?
For full home coverage, 3–4 units is ideal. Place one near bedrooms where your family sleeps, one in the kitchen near the stove, one near your furnace or water heater, and one on each additional floor. CO and gas risks don't stay in one room — your protection shouldn't either.
Does placement height matter?
Does placement height matter?
For carbon monoxide, height doesn't matter — CO mixes evenly with air, so any outlet at any height works. For natural gas and propane detection, placing the unit higher is better since these gases tend to rise and accumulate near the ceiling before spreading. When in doubt, a mid-to-high outlet gives you the best coverage for all three.
How long does the sensor last?
How long does the sensor last?
Cremores is built for long-term use and comes backed by a 3-year warranty. CO sensors typically have an active lifespan of 5–7 years — far longer than most people keep their old green-light detectors. When it's time to replace, the unit will let you know.
How do I know it's working?
How do I know it's working?
The live display shows real readings at all times — CO in PPM, gas percentage, humidity, and temperature. If numbers are showing on screen, it's actively monitoring your air. You don't need to guess, press a test button, or wait for a beep. You can see it working every single day.
Is setup complicated?
Is setup complicated?
Not at all. No Wi-Fi. No app to download. No account to create. No batteries to install. No ladder required. Simply plug Cremores into any standard wall outlet and within 60 seconds it begins monitoring your air. That's the entire setup — and it stays running as long as it's plugged in.
