Keeping your home mold and moisture-free starts with controlling moisture, and a correctly venting your bathroom fans is a key aspect of that control. Here’s how to ensure your bath fans work efficiently, keeping your air fresh and your surfaces dry:

Exterior Venting:

Always vent fans to the outside, not just into the attic or between walls. This directs moisture away from your home, protecting your structure and indoor air quality.

Use Hard Pipe:

Flexible ducts can sag and trap moisture. For maximum airflow, opt for hard piping. It's smoother inside, reducing airflow resistance.

Straight Runs:

The shortest distance between two points is a straight line, and it's true for venting too! Aim for as straight a run as possible to the exterior to minimize airflow restrictions.

Install Dampers:

A backdraft damper prevents outside air from entering when the fan isn't in use. It's a simple addition that enhances energy efficiency and comfort.

Test Airflow:

Use an exhaust fan flow meter to ensure your fan moves air effectively. Proper ventilation is key to removing moisture and odors efficiently. A tissue to the grill doesn't cut-it, you need to test!

Choose Low Sone Fans:

Noise matters! A low sone rating means a quieter fan, making your bathroom visits more pleasant without sacrificing ventilation.

Follow ASHRAE Standards:

Ensure installation and product selections meet ASHRAE standards for ventilation. These guidelines help optimize performance and energy efficiency.
