Is it necessary to install car window rain guards?

[McKarter]

Car window rain guards can be installed, with the following advantages: 1. Eliminates fog and smoke odor: On rainy days, you don't have to worry about slow smoke dissipation inside the car. It also helps eliminate fog. 2. Blocks sunlight: During the hot summer months, if you don't open the windows and rely solely on air conditioning, the air inside the car cannot circulate with the outside air, which is not good for your health. Opening the windows lets sunlight in, but with rain guards, you can slightly open the windows, and they will block direct sunlight from entering the car. 3. Maintains fresh air: In any environmental condition, it ensures the circulation of fresh air, keeping the interior suitable for human needs. 4. Reduces window fogging: By maintaining fresh air circulation, it prevents window fogging under any circumstances, ensuring clear visibility and safe driving.

I think window rain deflectors are quite necessary to install in certain situations, especially in areas with frequent rain or if you're used to slightly opening the windows for ventilation while driving. Having driven for several years, these things were a lifesaver during rainy summers—rain wouldn’t splash directly inside, and the air in the car could still circulate, preventing stuffiness or fogging. The installation process is usually very simple; some models just stick on without damaging the original car paint, and they’re quite affordable, costing just a few dozen yuan. Of course, there are downsides, such as potentially increased wind noise at high speeds or making the car look a bit outdated visually, though modern designs have improved a lot. Overall, I’d recommend them for those who live in rainy areas or smoke, as they can enhance daily driving comfort and safety, avoiding fatigue from keeping windows completely closed.

I think whether window rain guards are necessary depends on personal needs and driving conditions. I don’t have much driving experience, but from a cost-saving perspective, this item isn’t essential. If you only drive in sunny weather or rarely open the windows, spending money on it would be a waste. However, during rainy days, it can prevent rainwater from entering, provide ventilation for cooling, and serve as a supplement to the air conditioning system, extending its lifespan. When installing, make sure the size matches your car model; otherwise, it may not adhere properly and could lift or interfere with door closing. For safety, avoid overly thick designs that might obstruct the rearview mirror’s visibility. Overall, I don’t consider it a must-have, but its practical value is high, making it suitable for budget-conscious users to decide based on their habits.

I think installing window rain guards is pretty cool—they keep the rain out while adding a bit of personal style. Since I mostly drive in the city, they’re super handy when it rains; I can crack the window for fresh air without water getting in, and the car’s odors clear out faster. Installation is a breeze—just order online and DIY in minutes, super beginner-friendly. That said, looks are subjective—some think they ruin the car’s aesthetics, but I love the subtle curved designs. Pro tip: opt for UV-resistant material to block summer sun; at highway speeds, wind noise happens if windows are open too wide, but a slight gap keeps it quiet. Overall, not a must-have, but a practical and stylish quality-of-life upgrade.
