Is it better to ventilate a new car during the day or at night?

Ventilating a new car can be done either during the day or at night, as long as it's done when the car is not in use. Duration of ventilation for new cars: As is widely known, the release period of formaldehyde in new homes is quite long, and the same applies to new cars. Formaldehyde is slowly released from the interior and is difficult to completely remove. Therefore, the more practical approach is to stabilize formaldehyde levels within a safe range. The release period of formaldehyde can last from 3 to 15 years. The peak release period is the first 3 months, after which the release volume enters a continuous, stable, and low-emission phase. Methods to remove formaldehyde: Activated carbon is a traditional physical adsorption material that has been highly praised for dealing with pollution inside and outside the car. It has a large surface area and strong adsorption capacity, but its adsorption ability is limited and does not include decomposition functions. It needs to be replaced regularly during use to avoid secondary pollution when saturated.
