What Causes Musty Smell in the Car on Rainy Days?
1 Answers
Here are the specific reasons for the musty smell in the car on rainy days: Mold in the air conditioning system: Turning off the air conditioning only when parking and shutting off the engine can lead to mold growth. Due to high temperatures and humidity in summer, moisture remains in the air ducts and evaporator after the air conditioning is turned off, which is highly prone to mold. Before parking and shutting off the engine in summer, turn off the AC button and keep the fan running to dry the moisture in the ducts and evaporator. Using photocatalyst to eliminate odors: Photocatalysts can easily decompose mold, solving the problem of mold growth. They also effectively break down odor sources, accelerate the decomposition of organic substances and toxic gases, and improve air purification efficiency.
