Is Activated Carbon Dangerous in High Temperatures Inside a Car?
3 Answers
Activated carbon is not dangerous in high temperatures inside a car, as its ignition point is 300 degrees Celsius, which is much higher than the temperature inside a car. More information about activated carbon is as follows: 1. High Porosity: Activated carbon has a high porosity, making it highly effective at adsorbing harmful substances like formaldehyde and odors. The smaller the particles, the better the adsorption effect. If you are concerned about the air quality inside your car, you can purchase an activated carbon air purification device from a store. 2. Adsorption Properties: Using activated carbon is a physical method that does not cause secondary pollution. Activated carbon is a specially processed type of carbon with strong adsorption and filtration capabilities. However, once saturated, activated carbon can both adsorb and release formaldehyde. If possible, it is advisable to use it in combination with Huan Kang Nano Formaldehyde Removal Enzyme for better direct formaldehyde removal.
I've been using activated charcoal for deodorizing for a long time, always keeping small packs in my car. Even when summer temperatures soar, it's no problem. Activated charcoal itself is not flammable and generally doesn't release hazardous substances under high temperatures—it only absorbs odors. Like in my car, it's been there for ten years without ever catching fire or causing poisoning. However, avoid prolonged direct sunlight, such as leaving it on the dashboard under scorching sun, as accumulated heat can cause the absorbed substances to volatilize, reducing effectiveness or making odors seem worse. Always buy from reputable brands and don’t cheap out on low-quality products. The safest spots are the trunk or under the seats. Regular replacement is also crucial—typically every six months to maintain efficiency, ensuring a more worry-free drive.
I always keep activated charcoal bags in my car to deal with smoke or pet odors. Even when the car gets roasted to 50 degrees Celsius in summer, the charcoal bags remain intact. They have strong adsorption capabilities, stable physical structure under high temperatures, and are not prone to ignition or deterioration, posing very low risks. However, high temperatures can accelerate adsorption saturation, causing the charcoal bags to lose effectiveness faster, so it's important to avoid direct sunlight exposure—placing them on the dashboard, for example, is not ideal. Choosing high-quality products is key, as low-quality materials might release trace harmful substances under high temperatures. I usually buy sealed charcoal bags and place them in the glove compartment for ventilation, checking and replacing them quarterly to keep the air in the car fresh.
