Low-level carbon monoxide affects millions of Americans every year. Especially in cold months, when windows stay shut and you're breathing the same trapped air.

Take this 2-minute quiz to find out if low-level CO could be behind your symptoms.

70 PPM

9 PPM

Symptoms can start at

Takes 2 minutes · No sign-up required

Question 1 of 7

Which of these do you have in your home?

Select all that apply

Gas stove

Gas water heater

Furnace or gas heating system

Gas dryer

Attached garage

None of the above

Question 2 of 7

On average, how old are those appliances?

Less than 3 years

3–5 years

5–10 years

10–15 years

15+ years

Question 3 of 7

How would you describe your home's ventilation for most of the year?

Windows are closed 16+ hours a day (sealed for AC in summer, heat in winter)

Windows are open most of the day (16+ hours a day)

Question 4 of 7

Where did your CO detectors come from?

Home Depot / Lowe's / Walmart or similar store

Came with the house, or my landlord installed it

I purchased a professional-grade low-level CO detector

I don't have CO detectors

CO detectors sold in stores are designed to prevent death, not chronic health issues.

Every standard detector — including models with LCD screens — is built to a minimum code that requires detection only above 70 PPM. It won't show any number below it.

Persistent health symptoms start at levels as low as 9 PPM.

One more thing: Standard CO detectors expire after 5 years. If yours is older, the sensor is dead — even if it shows a green light (which only indicates battery life).

Question 5 of 7

Which of the following symptoms do you experience?

Brain fog or unexplained fatigue

Frequent headaches or migraines

Sleep problems — trouble falling or staying asleep

Dizziness or lightheadedness

Ringing in the ears

Heart palpitations

Anxiety, low mood, or irritability

Question 6 of 7

How old are you?

Under 25

25–34

35–44

45–54

55–64

65+

The older you are, the faster carbon monoxide affects you.

Children, for example, don't show symptoms until years later. Their bodies are in peak mode. And because CO just accelerates the decline of your body, they only see the results years later. That's why older people see the symptoms very fast.

Question 7 of 7

What has your doctor told you about these symptoms?

Attributed it to age or stress

Said everything looks normal and wasn't sure

Gave me a diagnosis, but the treatment hasn't helped

I haven't brought it up with a doctor
