Air fresheners introduce fragrance into the cabin either as droplets, which transition to vapour, or as the fragrant molecules evaporating from a source. The fragrance will then diffuse into the air and masks with other odours or introduce a specific refreshing odour. Air fresheners come in many different type, sizes and scents. Diffuser or scented oil wick air fresheners are well-suited for general air freshening but will be less effective in eliminating prolonged odours from the car seats or carpets. Scented gel style of air refresher will be a better option. With the wide range of designs available in the market, you can also make the selection based on aesthetics and appearance. You may opt for something to blend with the design of your dashboard or use as an additional decorations that hang from the rearview mirror
