Winter Air Quality in Minnesota: Why It Gets Worse and How to Fix It

Sealing up tight for winter might keep the cold out — but it also traps stale air inside. That’s why indoor air quality (IAQ) can plummet during Minnesota winters.

Common winter IAQ issues:

• Dry air that irritates skin and sinuses
• Trapped allergens, dust, and pet dander
• Reduced oxygen exchange from lack of ventilation

Solutions:

• Install a whole-home humidifier
• Upgrade to HEPA or MERV-13 filters
• Consider an HRV/ERV for fresh air circulation

Cleaner air = a healthier winter.
