What are the methods to remove formaldehyde in a car?

Methods to remove formaldehyde in a car: 1. Ventilation: For the first six months after purchasing a new car or after interior updates, develop the habit of driving with windows slightly open to maintain fresh air circulation and accelerate the dissipation of odors inside the car; 2. Activated carbon adsorption: Activated carbon has strong adsorption properties and is a common method for removing formaldehyde in daily life. However, activated carbon reaches saturation quickly and needs to be replaced promptly; 3. Air compressor solvent atomization: Use an air compressor to evenly spray formaldehyde-removing solvent inside the car, ensuring the spray covers all interior components and corners; 4. Use car disinfectant: For faster odor removal, you can also visit a car care center for negative ion deodorization services; 5. Place items like orange peels, grapefruit peels, or onions inside the car. These fruits have coarse fibers with large pores in their peels, which can adsorb formaldehyde and mask odors, though the effect is minimal and requires frequent replacement.
I dealt with the formaldehyde issue in my new car last year. Ventilation is the quickest solution—after picking up the car, I opened the windows for two hours daily for a month. I placed activated charcoal packets under the seats and in the trunk, remembering to sun-dry them every two weeks for regeneration. In summer, I parked the car in direct sunlight, as high temperatures accelerate formaldehyde release, and opening the windows enhanced the effect. I spent about a hundred yuan on a car air purifier with formaldehyde decomposition function and placed it on the dashboard—test results showed a rapid drop in formaldehyde levels. For leather cleaning, I used a spray containing photocatalyst, which both removes stains and breaks down formaldehyde. Never use perfumes to mask the smell—that only treats the symptoms, not the root cause.
