Extractor fans are devices designed to remove stale air, moisture, and odors from indoor spaces. They are commonly installed in areas like kitchens and bathrooms, where humidity levels can rise quickly. By drawing out the air, these fans help maintain a healthier environment and prevent issues like mold growth. These fans work by creating a negative pressure that pulls air through vents or ducts. They come in various sizes and styles, including wall-mounted and ceiling-mounted options. Regular maintenance, such as cleaning the fan blades, ensures optimal performance and longevity of the extractor fan.
