Noise can stem from worn-out bearings, loose parts, or poor installation. Tighten screws, clean debris, or replace the fan motor. For quieter operation, choose a fan with a sone rating below 1.5.

Ducted: Vents moist air outside (more effective).

Ductless: Uses filters to recirculate air (less efficient, best for small spaces).

It removes excess moisture, prevents mold/mildew growth, eliminates odors, and improves air quality.
