This graph tells the whole story.
After installing an ERV, indoor CO₂ levels dropped sharply — a clear, measurable sign of increased ventilation and proper air exchange.
What that means in real terms:
• Stale, high-CO₂ air is being exhausted
• Fresh, filtered outdoor air is continuously supplied
• The home is breathing the way it should
Why lower CO₂ matters:
• Better oxygen availability and mental clarity
• Reduced fatigue and headaches
• Improved sleep quality
• Healthier indoor air overall
An ERV doesn’t heat or cool your home — it corrects the ventilation deficiency most homes have.
If your home feels stuffy or you notice afternoon fatigue indoors, CO₂ buildup is often the silent culprit.
Healthy homes start with measurable air quality.
