How is water removed from a car's windshield?

It can be eliminated through the defogging function of the air conditioning system. The role of the cabin air filter has the following 3 points: 1. Provide fresh air: Prevents the car windows from fogging up, ensuring clear driver visibility and driving safety; Supplies fresh air to the cabin, preventing occupants from inhaling harmful gases and ensuring driving safety; Effectively sterilizes and deodorizes. 2. Ensure safety and hygiene: Maintains clean cabin air without bacterial growth; Effectively separates solid impurities such as dust, filter powder, and grinding particles from the air; Effectively blocks pollen to prevent allergic reactions that could affect driving safety. 3. Adsorb harmful substances: Adsorbs moisture, soot, ozone, and odors from the air, with strong and long-lasting moisture adsorption capabilities.
I've been driving for decades, and the water removal on the windshield primarily relies on the wiper system. The wiper uses a small motor to drive the blades back and forth, sweeping rainwater to the sides during rain. On sunny days, I also use the wipers to clean dust and insect stains, ensuring clear visibility. Besides wipers, the defogging function of the air conditioning is crucial. Pressing the windshield defogging button directs hot or cold air directly onto the inner surface of the glass, quickly evaporating condensation. If the rain is too heavy, the wiper speed can be adjusted—low speed for light rain, medium for moderate rain, and high for heavy downpours. I also apply a hydrophobic coating to the glass, which causes rainwater to bead up and roll off easily, reducing wear from frequent wiper use. Regular maintenance is essential: replace wiper blades every six months to prevent aging and breakage, and choose windshield washer fluid with an oil-film-removing function. These methods ensure driving safety by keeping the view unobstructed by water.
