Basements require adequate air circulation to help prevent conditions that are conducive to mold growth. Here are some ideas to help improve the air in your basement:
Install an air exchanger, or HRV (heat recovery ventilator) system
Install a stand-alone ventilation unit, such as the EZ Breathe system
Run the fan on your current forced-air furnace system year-round
Create passive ventilation by opening the windows along with oscillating fans running in the basement area
Keep the basement free of clutter, unnecessary retentive materials, and ensure large items such as sofas or cabinets are at least 4-6” away from any exterior wall
