How to Remove Formaldehyde in a Car?

Methods to remove formaldehyde in a car: Thoroughly clean the car interior, use an air compressor to evenly spray photocatalyst inside the car, wait for the solvent to dry, then perform a second spray to ensure all interior components and corners are covered, and try to open windows frequently for ventilation to maintain air circulation inside the car. A car is a non-track vehicle powered by an engine, equipped with four or more wheels, primarily used for transporting passengers and goods, or towing vehicles that carry passengers and goods. Cars are divided into passenger vehicles and commercial vehicles. Passenger vehicles mainly include standard passenger cars, convertible cars, luxury cars, compact cars, roadsters, hatchbacks, station wagons, multi-purpose vehicles (MPVs), forward-control passenger cars, off-road vehicles, and special-purpose passenger cars. Commercial vehicles mainly consist of buses, semi-trailer tractors, and trucks.
Recently I got a new car, and that pungent smell is caused by formaldehyde. I make it a habit to roll down the windows for at least ten minutes before driving every day, letting fresh air circulate. I've placed several bamboo charcoal bags in the car—they work like tiny vacuum cleaners absorbing formaldehyde, but they need to be taken out regularly and sun-dried to maintain effectiveness. In the summer heat, formaldehyde evaporates faster, so I park in the shade and leave all the doors open for half a day to air it out. For a more professional solution, I spent some money on a photocatalyst treatment, which breaks down formaldehyde into harmless substances. After a few months of use, the materials stabilize and the smell fades, but early-stage treatment shouldn't be neglected to avoid respiratory issues. Ventilation is the easiest method—just stick with it.
From an experimental perspective, formaldehyde primarily originates from interior plastics and adhesives, requiring specific methods for removal. I frequently open windows for ventilation, which effectively dilutes its concentration. For activated carbon packs, I recommend choosing reputable brands and placing them under seats and in the trunk to absorb molecules. I highly recommend car air purifiers equipped with formaldehyde filters, as they immediately filter out harmful substances upon activation. Photocatalytic coatings utilize light to decompose formaldehyde, offering long-lasting effects. Controlling temperature and humidity inside the vehicle is crucial—high temperatures accelerate release, so I try to park in breezy areas. New car materials gradually stabilize over time, and odors naturally diminish after two to three months. Combining ventilation with absorption methods is both scientifically sound and practical.
There's always a new smell in the commuter car, and my approach to dealing with formaldehyde is quite simple. When parking, I roll down the windows for five minutes to ventilate, and I often drive with the windows slightly open for air exchange. Buying a few packs of activated charcoal to stuff in the car is cheap and effective, just remember to flip them regularly. In a hurry, I use a formaldehyde spray, wait for the smell to dissipate, and then open the windows. The smell fades after driving a new car for a while, but the key is not to keep the doors closed all day—ventilate more.
