Failing to use an extractor fan can result in increased humidity levels, the growth of mold, and the lingering scent of yesterday's dinner. Neglecting this appliance may also lead to costly repairs or replacements due to gradual wear and tear. Understanding the importance of regular use and maintenance can save homeowners from unnecessary headaches and expenses.
