What is the best method to remove formaldehyde from a car?

Methods to remove formaldehyde from the car interior: 1. Bamboo charcoal bags: Place some bamboo charcoal bags in the car. The bamboo charcoal inside these bags has a porous structure with strong adsorption capabilities, effectively absorbing harmful gases such as formaldehyde, benzene, and sulfur dioxide from the car air, while also releasing natural minerals. Additionally, bamboo charcoal bags have excellent moisture absorption properties, helping to dehumidify, deodorize, and prevent mold in the car. 2. Car air purifiers: Install a car air purifier in the vehicle. Car air purifiers can filter the air inside the car, not only effectively removing formaldehyde but also significantly eliminating pollutants like PM2.5, TVOC, odors, and bacteria, thus creating a healthier car environment. 3. Frequent window ventilation: This method is the most economical and practical. Keep the car windows open as much as possible while driving, and even when using air conditioning, opt for the external circulation mode to maintain air flow inside the car. This helps eliminate odors and formaldehyde from the car air, reducing the accumulation of formaldehyde. 4. Photocatalyst spraying: For car formaldehyde removal, you can also visit a professional car detailing shop for photocatalyst spraying. Photocatalyst, similar to regular air fresheners, comes in liquid form and mainly contains titanium dioxide. Upon absorbing ultraviolet rays from sunlight or artificial lighting, it reacts to produce substances that can break down organic compounds and their nutrients, decomposing harmful substances like formaldehyde, benzene, and toluene into harmless water and carbon dioxide. This process purifies the air, effectively preventing mold, eliminating odors, and providing antibacterial and bactericidal effects.
When I first got my new car, I was also troubled by the formaldehyde smell and tried many methods. The most effective was opening the windows for ventilation—I'd open all doors and windows for 5 minutes before getting in, and keep them slightly open while driving. I also placed several bamboo charcoal bags in the car: two under the seats and one in the trunk. I found that sun exposure worked well too—on weekends, I'd park the car in an open area with the windows slightly cracked and leave it in the sun for most of the day, which showed noticeable results. Someone recommended a car air purifier, which I also used—it really improved air circulation. After six months, the smell is basically gone. Combining these methods worked best.
