Almost every home has a carbon monoxide detector.
But very few people monitor something that can reveal poor air quality long before it becomes a health problem:
🫁 CO₂ levels.
According to indoor air quality expert J.W. Biava, measuring CO₂ is one of the easiest ways to understand if your home has enough ventilation.
Why?
Because high CO₂ levels usually mean stale indoor air that isn’t being refreshed with fresh air.
In fact, indoor air experts often say:
“Dilution is the solution to pollution.”
In other words, the more fresh air entering your home, the lower the concentration of indoor pollutants.
In this clip from The Smartest Doctor in the Room, J.W. explains how he monitors CO₂ in his own home and how ventilation systems can dramatically improve indoor air quality.
If you're concerned about what you’re breathing inside your home, testing is the best place to start.
The Immunolytics Mold Check-Up Kit makes it easy to begin testing your home for mold and understanding your indoor air quality.
Your health starts where you live.
