Benefits: Better Fuel Efficiency: Uses less energy by cooling pre-chilled air. Cleaner Air: Blocks pollutants, allergens, and exhaust fumes. Quieter Ride: Reduces external noise for a more comfortable drive. When to Use It: Hot Weather: Cools the cabin faster. Polluted Areas: Keeps harmful fumes out. Odor Control: Prevents bad smells from entering. When to Avoid It: Cold Weather: Can cause foggy windows—fresh air helps clear them. Long Trips: Continuous use may increase carbon dioxide levels. Respiratory Concerns: Fresh air is better for passengers with allergies. Bottom Line: This small button improves comfort, efficiency, and air quality—perfect for extreme heat, pollution, or odors
