A Guide to Residential Ventilation Exhaust Fans

A Guide to Residential Ventilation Exhaust Fans

Exhaust fans are often overlooked within the ventilation system in homes and commercial buildings, despite their extreme importance. Without the proper ventilation implemented into the system, your home can become filled with harmful contaminants and pathogens that may cause disease.


Pollutants may include harmful gases, smoke from cigars or cigarettes, dander from pets, pesticides, asbestos, dust mites, or even paint fumes that enter the indoor air from daily activities performed in the home or office. These pollutants begin to add up, getting caked into the ventilation system and festering for long periods of time. Over time, these pollutants begin spreading throughout the entire vent system, causing illness and disease.

Recommended Sizing

The size of your ventilation exhaust fans totally depends upon the size of the building they are being installed in. To properly ventilate the area, you should measure the entire area’s dimensions, then calculate the air usage for every person in the room. This should offer a good basis to begin the fan installation. A professional technician can handle all of this, should the task seem daunting to a homeowner or business owner.

How Helpful Are Fans?

We spoke on the numerous pollutants and contaminants that can enter an air system above. Now, no one can actually see these contaminants because they are hidden away overhead or completely invisible. That does not mean they aren’t there, however.

Fans will effectively push these contaminants outdoors where they will dissipate instead of spreading through the enclosed space of your home. Without fans, the pollutants would begin festering and causing illness due to having nowhere to move.
