As summer approaches, the smell inside your car tends to become more noticeable. The limited space in a vehicle can trap unpleasant odors, making it harder for drivers to stay focused and potentially affecting safe driving. Moreover, harmful substances like formaldehyde, benzene, and TVOC not only cause bad smells but also pose serious health risks to those inside the car. Therefore, if you detect any odor, it's important to address it promptly and not ignore it.
Question 1: What Causes Odor Inside the Car?
The interior of a car contains many materials such as plastics, rubber, fabrics, paints, insulation, and adhesives. These materials often release volatile organic compounds (VOCs) over time, contributing significantly to the smell inside the vehicle—especially in new cars. Additionally, moisture from the air conditioning system can create an ideal environment for mold growth. Condensed water from rain or snow, combined with dust, accumulates on the evaporator and leads to mold development in dark corners of the AC system. This results in a musty smell that lingers when the AC is turned on.
Other sources of odor include fruit peels, snacks, or spilled drinks that get trapped in the car’s corners, leading to mold and decay. Wet carpets or seats after rain, unused shoes in the back, or forgotten clothes can all emit unpleasant smells. When the air conditioner is running, these odors circulate throughout the cabin, worsening the issue.
Personal habits also play a role. Eating in the car, smoking, or leaving trash around can lead to long-term odors. Additionally, parking in areas exposed to sunlight, darkness, or near garbage dumps can accelerate the buildup of unwanted smells.
Question 2: How to Manage Odor and Pollution Inside the Car?
Many people use citrus peels like orange or grapefruit to mask the smell in a new car, but this only covers up the problem temporarily. It doesn’t eliminate the actual pollutants like formaldehyde.
Car air fresheners are another common solution. While they may provide a pleasant scent, low-quality products can degrade under high temperatures, especially in summer, and release harmful chemicals instead of improving air quality.
A simple and effective method is ventilation. Before starting the car, open the windows to let fresh air in. When parked, leave a small gap to maintain airflow. This helps reduce the concentration of harmful gases and improves overall air quality inside the car.
Activated carbon is a popular deodorizer that absorbs odors and some pollutants. However, its effectiveness lasts only about 6–10 months, and it needs regular replacement. It works through physical adsorption, making it safe, but it doesn't break down the harmful substances completely.
An advanced option is Qingyi Lan Nasen, a specialized treatment material designed to absorb and decompose harmful substances in vehicles. Unlike activated carbon, it doesn’t release toxins even at high temperatures, avoiding secondary pollution. It’s safe for families and children, though it comes at a higher cost. For new cars during hot summers, it offers strong and lasting performance, making it a smart choice.
Controlling in-car pollution is essential for maintaining a healthy driving environment. Don’t wait until the smell becomes unbearable—take action early to protect your well-being and enjoy a fresher, safer ride.
