Spot Ventilation Solutions

Spot ventilation refers to localized exhaust fans, commonly used in kitchens and bathrooms.

Kitchen Ventilation

Install a quality range hood vented to the outside with the recommended CFM (cubic feet per minute) air flow for your stove. Make sure to choose a range hood that’s both efficient and quiet, such as the 52000 series from Broan, which has a 370 CFM centrifugal blower and multispeed control. Run the fan whenever you cook to remove cooking fumes, smoke, carcinogens, grease and moisture.

You may be thinking, “But my microwave already has a fan. Why do I need a vent hood?” While over-the-range microwaves are convenient, they don’t extend far enough over the stove for proper venting, and they often aren’t vented to the outside.

Bathroom Ventilation

The bathroom is the biggest source of moisture in the home. The best line of defense against moisture in the bathroom is a quality vent fan, such as the Ultra Green bath fan from Broan. Install one in each bathroom; and use them during and for 15-20 minutes after bathing to remove excess moisture that can cause mold and mildew.

And, like range hoods in the kitchen, it’s important that the bathroom vent exhausts all the way to the outside. If the vent stops in the attic, all that moisture and humidity is trapped in the attic, creating a breeding ground for mold and mildew. Watch How to Properly Vent a Bathroom Exhaust Fan in an Attic for details.
