Also, when it’s raining outside, it is better to select in-vehicle circulation mode. Make sure you always select the right ventilation depending on the environment.

Less Bathing and Cooking

Moisture Free Products

Using Moisture proof products is also a wise thing to do. If the product is not able to absorb moisture, it won’t be able to cause humidity in the environment. Using desiccant or activated carbon, and equipping a dehumidifier can do the job. Mostly the seats cover and the cushion placed inside the car is the major cause of building moisturizer inside the vehicle. Get rid of anything which can absorb the moisture.

Rainy Season
