How to Remove Formaldehyde from the Car?

Methods to remove formaldehyde from the car include: 1. Place several packs of bamboo charcoal in the car. Bamboo charcoal has strong adsorption capabilities, allowing it to absorb moisture, sulfides, chlorides, formaldehyde, and other harmful substances from the air while also purifying air and water quality. 2. Frequently open windows for ventilation. When driving, try to keep the windows open as much as possible. Even when using air conditioning with windows closed, opt for the external circulation mode to maintain air circulation inside the car. 3. Install a car air purifier. A car air purifier can filter the air inside the car, effectively removing not only formaldehyde but also significantly reducing PM2.5, TVOC, odors, bacteria, viruses, and other air pollutants, thereby creating a healthier in-car environment.
When I first got my new car, the formaldehyde smell was really overwhelming. Now I've summarized a few practical tips. The most important thing is to maintain ventilation—every day before driving, I roll down all four windows for ten minutes to air it out, and on weekends, I let the car sit in direct sunlight for several hours, making sure to leave a small gap in the windows for heat to escape. I stuffed seven or eight bamboo charcoal bags in the trunk and hid a few under the seat cushions, replacing them with fresh ones every couple of months. Later, I bought an in-car air purifier with an activated carbon filter—it runs quietly at night but works quite well. I noticed that placing a sunshade mat on the dashboard actually traps formaldehyde, so I removed it entirely and now only keep the original floor mats, wiping down the interior edges and corners with a damp cloth three times a week. After sticking to these methods for half a year, the weird smells in the car are basically gone.
With kids frequently riding in the back seat, I'm particularly concerned about formaldehyde removal. When summer temperatures rise, I notice a pungent odor in the car, so I always try to park in shaded areas. If the car must be exposed to direct sunlight, I place silver reflective panels on the windshield beforehand. I've replaced the cabin air filter with an activated carbon version, changing it every two months, and always open the windows for two minutes before turning on the AC. Last week, I rented a formaldehyde detector online and immediately performed photocatalyst treatment when the concentration exceeded safe levels—this proved much more effective than simply placing pomelo peels. I make it a habit to ventilate the car by opening doors ten minutes before picking up or dropping off the kids. The leather seats are cleaned weekly with specialized products, and I keep two pots of English ivy in the trunk—though they work slowly for formaldehyde removal, their presence gives me peace of mind.
