What is the most effective method to remove formaldehyde from a car?

You can use bamboo charcoal bags, which have strong odor adsorption capabilities. Develop the habit of opening doors and windows before driving to allow circulating air to dilute and disperse toxic gases inside the car. Fruit peels also have deodorizing effects, such as those from pomelos and lemons.
To remove formaldehyde, I believe the most effective method is persistent ventilation—simple yet practical. I always open the windows to air out the car for a few minutes before driving, especially during the new-car phase when the formaldehyde odor is particularly strong. Frequent ventilation quickly reduces the concentration. In summer, parking the car under the sun for a while allows heat to accelerate formaldehyde release. I also use activated charcoal bags—bamboo charcoal ones are affordable and highly effective at adsorption—but remember to replace them monthly, as they lose effectiveness once saturated. I’ve also tried car air purifiers; opt for models with HEPA filters and activated carbon to thoroughly clean the air and avoid inhaling harmful gases. Additionally, leaving the sunroof slightly open when parked maintains airflow, and over time, the new-car smell fades faster. Consistency is key—don’t underestimate these small daily habits, as health comes first.
