How Long Does It Take for a New Car to Be Free of Formaldehyde?

[DeBethany]

Generally, it takes 1-3 months for a new car to remove formaldehyde, while some cars may require about a year for complete formaldehyde removal. The actual time depends on the quality of the car's materials. Methods to accelerate the removal of formaldehyde in the car: 1. Within the first 6 months after purchasing a new car, frequently expose the car to sunlight with the windows open for ventilation. This can speed up the release of formaldehyde, significantly reducing its concentration. 2. Place bamboo charcoal bags in the car. The bamboo fibers in these bags are porous and have strong adsorption capabilities, effectively absorbing harmful substances like formaldehyde, benzene, and sulfur dioxide while releasing natural minerals. Bamboo charcoal bags also have excellent moisture absorption properties, helping to dehumidify, deodorize, and prevent mold in the car. 3. Purchase and use a car air purifier. Car air purifiers can filter the air inside the vehicle, not only efficiently removing formaldehyde but also significantly eliminating PM2.5, TVOC, odors, bacteria, and viruses. 4. Visit a professional car detailing shop for photocatalytic formaldehyde removal. Photocatalytic formaldehyde removers are liquid-based, similar to regular air fresheners, with titanium dioxide as the main component. When exposed to natural or artificial ultraviolet light, they react to produce substances that can break down harmful organic compounds, converting carcinogens like formaldehyde, benzene, and xylene into non-toxic water and carbon dioxide. This effectively purifies the air, providing anti-mold, deodorizing, antibacterial, and antimicrobial benefits.
