How To Remove VOCs From New Car?

Now, we will explore various techniques and strategies to remove VOCs from a new car, ensuring a safer and more pleasant driving experience.

Letting Fresh Air In

One of the simplest ways to reduce VOC levels in a car is through thorough ventilation. Rolling down the windows while driving allows fresh air to circulate and replace the trapped indoor air. This practice is especially important during the first 6 months of owning a new car when VOC emissions are typically high.

Heat and Ventilation

To speed up the release of chemicals, the “baking out” method can be employed. By combining heat and ventilation, this process encourages the VOCs to be released into the air. Start by leaving the car in the hot sun with the windows open for several hours. 

This allows the chemicals to be expelled from the car’s interior. Then, open the windows wide and thoroughly air out the vehicle.

Cleaning Internal Surfaces

Cleaning all internal surfaces is another effective step in VOC removal. Use a mild solution of water with vinegar or washing soda to wipe down surfaces. This helps to eliminate any lingering chemicals and prevent mold issues. Choose a sunny day for cleaning to ensure quick drying and minimize the risk of mold growth.

Activated Charcoal and Baking Soda

Activated charcoal and baking soda are well-known for their absorbent properties and ability to absorb chemical odors. Place disposable plastic boxes containing activated charcoal or baking soda under the car seat to absorb any additional chemicals emitted by the car interior. These materials help neutralize and reduce VOC levels.

HEPA and Activated Charcoal Filters

Air purifiers equipped with HEPA filters and activated charcoal filters are highly effective in reducing exposure to ongoing interior chemical emissions. 

These filters capture and trap VOCs, improving air quality inside the car. Consider investing in a reliable in-car air purifier to further minimize VOC exposure.

Regular Cleaning and Maintenance

Regularly cleaning the car’s interior is crucial for removing chemicals that continue to be released and settle on surfaces. Dust, vacuum, and wipe down surfaces regularly to minimize VOC buildup. 

Additionally, parking the car in the sun whenever possible and ventilating it before driving off helps to release accumulated chemicals.

Minimizing Time Spent in the Car

Reducing the time spent in the car is an effective way to minimize exposure to harmful VOCs. Whenever feasible, consider alternative transportation methods like walking, taking the bus, or cycling. 

Not only does this reduce exposure to VOCs, but it also benefits the environment and saves on fuel costs.

Car Manufacturers’ Efforts

Car manufacturers are becoming increasingly aware of the importance of reducing toxic new car smells and VOC emissions. Many companies are taking steps to switch to water-based glues and incorporate more natural materials in their vehicles. 

Before purchasing a new car, check the manufacturer’s website or ask the dealer about their efforts to reduce VOCs in car interiors.
