Can rain deflectors really block rain?
3 Answers
Rain deflectors can block rain. Here is the relevant introduction: 1. Function: Rain deflectors are attached to the rearview mirror with double-sided tape. When it rains, the deflectors can greatly prevent raindrops from splashing or flowing onto the rearview mirror, ensuring that the rearview mirror always provides the driver with a clear view. 2. Benefits: The formal name of rain deflectors is 'sun and rain visors.' Their biggest advantage is that during rainy days, they allow the window to be rolled down to a certain height without letting raindrops enter. Moreover, they leave a small gap between the window and the roof, which also serves a ventilation purpose.
Rain guards are indeed effective at blocking rain, especially when driving with the windows slightly open for ventilation on drizzly days. I've used them for several years and found that during light rain, almost no water gets inside—the airflow is directed outward, keeping the interior dry. However, their effectiveness diminishes in heavy rain or strong winds, as a few drops can still drift in. I recommend purchasing high-quality rain guards made from durable materials and ensuring thorough cleaning of the window edges before installation to prevent adhesive failure and detachment. Overall, rain guards are highly practical for daily commutes, enhancing comfort during rainy drives, but regular inspection and maintenance are necessary to prevent aging from affecting performance. Don't expect too much during heavy downpours, but under reasonable conditions, they are absolutely reliable.
The mechanism of rain guards is quite simple: by altering the direction of airflow, rainwater is diverted away from the car. When driving, the wind speed causes raindrops to be swept away by the airflow, making it harder for them to enter the window. I've tried opening the window slightly on the highway during light rain, and the rain guards worked excellently—the rain was completely blown away. However, if the rain is too heavy or the car speed is slow, insufficient airflow reduces their effectiveness. Choosing the right size and a design that fits the car model is also crucial, as improper installation can obstruct visibility. Overall, rain guards are practical and worth considering to enhance the driving experience.
