It takes 3-5 months to remove formaldehyde from a new car. Hazards of excessive formaldehyde: Excessive formaldehyde is a common environmental pollution issue in new cars. High concentrations of formaldehyde can cause dizziness and nausea. Formaldehyde is a toxic gas, and excessive inhalation can lead to formaldehyde poisoning, which has a significant impact on human health. Effective methods to remove formaldehyde: Bamboo charcoal bags: The bamboo charcoal in these bags has a porous structure with strong adsorption capabilities, effectively absorbing harmful gases such as formaldehyde, benzene, and sulfur dioxide inside the car while releasing natural minerals. Bamboo charcoal bags also have excellent moisture absorption properties, helping to dehumidify, deodorize, and prevent mold in the car. Car air purifiers: Car air purifiers can filter the air inside the vehicle, not only effectively removing formaldehyde but also significantly reducing PM2.5, TVOC, odors, bacteria, viruses, and other air pollutants, thereby creating a healthier in-car environment.

When I first bought my new car, the most annoying thing was that pungent smell. There's no fixed timeline for removing formaldehyde. Ventilation is key—I open the windows for at least half an hour every time I park. High temperatures and direct sunlight speed up the release, and in summer, you'll see improvement in just 3-5 days. But to truly reach safe levels, it usually takes 1-2 months for an average car. I recommend adding activated charcoal bags or photocatalytic sprays, which can shorten this to a few weeks. New cars have lots of plastic parts, and the initial release is high right after production—avoid putting kids in the car for the first few days. The exact duration depends on the car's materials and how diligent you are.

Don't rush to take your kids for a ride in a new car—I learned this the hard way. Removing formaldehyde can't be hurried; you need at least a few weeks of ventilation, and opening the sunroof on the highway is most effective when the wind is strong. Placing pothos or pineapple peels in the car can help, but the key factors are temperature and air circulation—it may take two to three months in winter. Families with kids should be extra cautious, as children are more sensitive to formaldehyde. Test the concentration first before taking action. I also use a car air purifier—it's slow but offers peace of mind, since health comes first.

The speed of formaldehyde removal depends on ventilation efficiency and personal methods. I open the windows and expose the car to sunlight for half an hour every time I refuel, as high temperatures accelerate the release, and the plastic smell of the new car gradually fades. Pure natural methods may take several weeks or even two months, especially in winter. Later, I added formaldehyde removal spray and activated carbon pads, which significantly improved the situation in three to four weeks. The main sources of formaldehyde in the car are seat adhesives and interior parts. Buying a car with low VOC certification can save trouble. Don’t overlook the air conditioning’s internal circulation, and regular cleaning of the filter is also important.
