Common Questions

About Indoor Air Quality

Why is indoor air quality worse in Maine homes?

Maine homes are built tight to keep heat in during winter. That same tight envelope traps dust, pet dander, cooking fumes, and moisture inside. Without proper ventilation and filtration, indoor air can be 2-5 times more polluted than outdoor air.

What is an HRV and do I need one?

A Heat Recovery Ventilator (HRV) brings fresh outdoor air into your home while recovering heat from the stale air being exhausted. In tightly sealed Maine homes, an HRV dramatically improves air quality without wasting energy. We recommend them for most homes in Maine.
