The smell in a new car comes from many sources, including formaldehyde. The odor in a new car mainly originates from car seat cushions, plastic products, roof felts, etc. The lower-end the car, the cheaper the materials used. The adhesives in these materials contain formaldehyde, benzene is used for coloring, and plastic decorations use agents containing formaldehyde and TVOC. Additional information: Methods to remove formaldehyde from a new car are as follows: 1. Open windows frequently and ventilate well: Formaldehyde is directly related to temperature; higher temperatures lead to higher concentrations, making ventilation crucial. When driving, keep the windows open as much as possible to ventilate the car. This is the most direct method to accelerate air circulation inside the car, helping to eliminate odors and formaldehyde. However, it takes a long time and may not be convenient in bad weather. 2. Bamboo charcoal bags: Bamboo charcoal in these bags has a porous structure with strong adsorption capabilities, effectively absorbing harmful gases like formaldehyde, benzene, and sulfur dioxide from the car while releasing natural minerals. Bamboo charcoal bags also have excellent moisture absorption, helping to dehumidify, deodorize, and prevent mold in the car. 3. Car air purifiers: Car air purifiers can filter the air inside the vehicle, effectively removing PM2.5, toxic and harmful gases, odors, bacteria, viruses, and other pollutants. However, windows need to be closed when using them. 4. Photocatalysts: Photocatalysts, like common air fresheners, are liquid-based and primarily composed of titanium dioxide. When exposed to ultraviolet light from sunlight or artificial lighting, they react to produce substances that can break down organic compounds and their nutrients. This process decomposes harmful substances like formaldehyde, benzene, and toluene into harmless water and carbon dioxide, thereby purifying the air. It effectively prevents mold, eliminates odors, and kills or inhibits bacteria.

When I bought my new car last year, I was also worried whether that smell was caused by formaldehyde. In fact, the new car smell is a mixture of various chemicals, including formaldehyde, benzene, and other volatile substances, which come from the seat leather, plastic panels, and adhesives. These substances are released intensely right after the car leaves the factory. It's not just the smell of formaldehyde alone, but rather a gas similar to new furniture. Short-term exposure might be fine, but I recommend keeping the windows open for ventilation when you first get the car, especially in summer when higher temperatures speed up the release. You can also place activated charcoal bags to absorb the odors or buy a car-specific air purifier. Usually, the smell fades significantly after a month or so of driving. If it persists, it's best to check if there are any defects in the car's interior materials. Remember, health comes first—especially when children or elderly are in the car, airing it out beforehand provides peace of mind.

As a parent who often drives to pick up my kids, I pay special attention to the new car smell. Formaldehyde is part of it, but not the only harmful substance. It mixes with other chemical volatiles from the interior, which may irritate the eyes or throat. Fortunately, this is a temporary phenomenon, as manufacturers have controlled safety standards during production. From personal experience, the smell is strongest in the first two weeks. Avoid running the AC in recirculation mode with windows closed all day, as this accumulates odors. When parked, leave the sunroof or side windows slightly open and use sunlight exposure to accelerate volatilization. You can also wipe interior surfaces with diluted white vinegar water—simple yet effective. Over time, the smell naturally fades, so don’t rush to mask the root issue with air fresheners. Ventilate the car for half an hour daily, and it should return to normal in about a month.

The new car smell is indeed mainly chemical volatiles, including formaldehyde components, originating from manufacturing processes such as adhesives and plastic parts. It's recommended to address it immediately after purchase: find an open area to ventilate with windows open for at least half an hour daily; spray disinfectant spray on the interior or place tea bags and orange peels as natural odor absorbers; avoid using air fresheners right away to prevent mixing odors which can be more pungent. Volatilization accelerates when temperatures rise, so prioritize using the air conditioning in external circulation mode with adjusted fan speed. Generally, the smell weakens after a few weeks of driving. If the odor persists, check if there are defects in new components like the dashboard or carpet.

From an automotive assembly perspective, the new car smell is caused by residual gases from materials like plastics and adhesives used in manufacturing, which contain formaldehyde but in relatively low proportions. Modern vehicles employ coatings and production techniques to minimize harmful substances during manufacturing, but newly purchased cars inevitably have odors in enclosed spaces. Consumers are advised not to panic prematurely—ventilation is key: open windows for ten minutes before driving in the morning and use bamboo charcoal bags to absorb excess gases. The smell naturally diminishes after a month and nearly disappears within six months. Parking outdoors in direct sunlight on sunny days is particularly effective, while avoiding enclosed garage storage. Regularly cleaning car carpets can also accelerate odor removal.

When I first got the car, the smell inside the cabin was really unpleasant. People often refer to it as the 'new car smell,' which mainly consists of formaldehyde compounds and other volatile organic compounds. From my personal experience: the smell was strongest in the first week. I rolled down the windows for ventilation for about an hour every day during my commute. On weekends, I parked under a tree and left all the doors and windows open to let the air circulate. I also placed pineapple peels or activated charcoal boxes under the seats to absorb the odor. Avoid using strong chemical deodorizers to prevent introducing new problems. After about three to four weeks, the smell noticeably faded, and it disappeared completely by the time the car's break-in period was over. Remember to use the air conditioner's external circulation mode frequently during the initial stage to prevent the smell from building up and affecting your driving mood.
