These fans are designed to improve air circulation and remove excess moisture, odors, and pollutants from your living space. Here are a few reasons why I believe they are necessary:

A 4 in line exhaust fan helps to remove these pollutants by constantly circulating fresh air into the room and expelling stale air outside.

2. Eliminates Excess Moisture

Excess moisture in the air can lead to mold growth, which not only damages your walls and ceilings but also poses serious health risks.
