1. The most common method of in addition to formaldehyde in the car is window ventilation, and this method has almost no cost. However, ventilation also has disadvantages. It is impossible to completely remove formaldehyde through window ventilation. It can only play a supplementary role in in addition to formaldehyde.
2. The easiest way is to drive the vehicle to a place where there is no influence and the sun can shine directly, and open all the doors for 2 hours to remove the sun. This method can be used for 2-3 times, and the carcinogenic polycyclic aromatic hydrocarbons in the car can also remove the odor. This method is very easy to use. But pay attention to the damage of high temperature to the car and pay attention to maintenance.
3. Activated carbon is a traditional physical adsorption material, which is well received in indoor and outdoor pollution control. It has large specific surface area and strong adsorption capacity, but its adsorption capacity is limited and it does not have decomposition function. It needs to be replaced regularly when it is used, otherwise it may produce secondary pollution when it is saturated.
5. An air purifier can be placed in the car. The current air purifier can not only remove harmful gases such as formaldehyde and benzene, but also remove odor and sterilize. It is especially suitable for new cars in winter, but it is also expensive and only works when it is started.
6. Photocatalyst is an auxiliary method to control formaldehyde, mainly because it can't decompose formaldehyde in the dark or without light, can't work all day, has a small range of action, and can't deeply and effectively remove indoor formaldehyde. In addition, photocatalyst itself is also a chemical, which needs to be used with caution?
