ERV ventilation systems, or Energy Recovery Ventilation systems, are suitable for installation 

in areas with high humidity or poor air quality. Here are some suitable locations in Idaho for 

ERV ventilation systems:

- **Areas with High Humidity**: Some areas in northern Idaho near the mountains have 

relatively high humidity levels, such as Nordman, where the average humidity reaches 95% 

in January and 54% in August, with high humidity levels for most of the year. Additionally, 

northern areas like Sandpoint also experience high humidity and rainfall during winter. 

Installing ERV ventilation systems in these areas can effectively control indoor humidity 

and prevent mold growth.

- **Areas with Poor Air Quality**: Some areas in Idaho suffer from poor air quality due to 

factors such as wildfire smoke. For example, cities near wilderness areas, such as Boise 

and Idaho Falls, are easily affected by smoke during wildfire season. ERV ventilation systems 

can improve indoor air quality by providing ventilation without introducing excessive 

pollutants.
