Placing solid air fresheners in the car can be hazardous, so it is best to avoid doing so. The ingredients of popular air fresheners on the market mostly consist of ether, aromatic fragrances, and other components. When these ingredients are released into the air, they decompose and deteriorate, becoming pollutants themselves. Composition of Solid Air Fresheners: Solid air fresheners are composed of ethanol, fragrances, deionized water, and other ingredients. They mask unpleasant odors by emitting fragrances, thereby reducing discomfort caused by bad smells. Shape of Solid Air Fresheners: Solid air fresheners are water-based gel substances with no fixed shape, requiring container packaging. The direction of fragrance emission is limited, and the scent is often too faint. Additionally, this gel does not fully evaporate, leaving residues behind, and the packaging becomes waste that pollutes the environment.

Placing solid air fresheners in the car is not very safe in high-temperature environments. As someone who frequently drives long distances, my car parked outdoors in summer can reach temperatures of 60-70°C, causing the plastic shell of solid air fresheners to deform and melt, releasing chemicals like benzene or formaldehyde. Prolonged inhalation can lead to headaches and nausea. Even worse, melted residue can seep into dashboard crevices, making cleanup difficult and potentially causing internal corrosion. It's advisable to avoid hanging them in direct sunlight—placing them in the glove compartment or ventilated trunk space is better. When purchasing, opt for eco-friendly brands with low-volatility ingredients, ideally using them in winter and removing them in summer. Regularly air out the car by opening windows for a few hours before getting in.

As someone with respiratory sensitivities, I believe solid air fresheners in cars should be used with caution. The slowly released chemicals can easily accumulate in enclosed spaces, potentially triggering allergies or asthma, especially when the scent becomes stronger in hot weather, causing discomfort. I once coughed for several days after using a cheap product. Check the ingredients to avoid alcohol or volatile organic compounds (VOCs), and opt for natural fragrances for greater safety. When using, don't place it too close to seats; secure it on the outer side of air vents and keep it away from children or pets. Replace it regularly to prevent deterioration, and if the smell becomes abnormal, stop using it and switch to natural alternatives like activated charcoal bags.

Based on my years of car usage experience, solid air fresheners can be used but require proper methods. Avoid placing them near heat sources like air vents or above the engine, as high temperatures can cause melting and flammability. Choose reliable brands, place them in cool areas, and check labels. Personally, I use bamboo charcoal bags or baking soda with vanilla as safer and more affordable alternatives. Since car interiors are small spaces with high chemical concentration, remember to open windows for ventilation periodically. In summer, park in shaded areas to avoid direct sunlight exposure, while winter poses fewer issues.
