Use this table to calculate the Cubic Feet per Minute (CFM) capacity needed for an exhaust fan in a specific room. A ventilation fan should meet at least the minimum standard CFM to provide proper exhaust. Before you install bathroom or kitchen exhaust fans, start here to determine what you need to proceed for proper ventilation.
Kitchen exhaust fans have to be sized properly for your kitchen. Overhead exhaust fans capture the smoke and grease mist that could coat your kitchen surfaces. Some of the cook exhaust fans come with built-in lights.
Does your garage heat up like an oven? Once the heat builds up in the objects in the garage, they can radiate heat for hours after the direct sun is gone. Insulation and ventilation fans will help reduce the temperature inside your hot garage.
Turbine vents can replace the hot air in your attic in minutes. Mother Nature blows across the fins in the roof turbine vents as they exhaust the heat build up.
Crawl spaces collect and condense water vapor. Crawl space ventilation is necessary to prevent mildew or rot. Vapor barriers may provide better protection than crawlspace vents.
Bathroom exhaust fans are vital components of your home's ventilation system. Bathroom fans not only exhaust offensive odors, they also pipe vast amounts of humid air to the exterior of your home. Bathroom vent fans come in all types and sizes, but I prefer the ones that have the fan motor located in the attic. These residential bathroom exhaust fans are the quietest ones I have ever used, and they are extremely powerful.

Exhaust moist, hot air from your attic. Turbine roof vents work with Mother Nature to pull this air outside...for free.
Venting your clothes dryer directly into the garage could be a building-code violation and a bad idea. Dryer vents exhaust a large amount of water vapor. Putting this condensation into your garage could create rust on unpainted surfaces, and worse, mold inside the walls and ceiling. Clothes-dryer venting should be to the outside.
Inlets for fresh air resupply the exhausted air in your home. Without this fresh air you have the potential for back draft of dangerous gases from your appliances.
