Benefits of Side Window Deflectors
- Reduce wind noise. Opening your windows as you drive can let in a lot of noise and wind, depending on where you’re driving. The best side window deflectors reduce wind noise. They redirect wind up and over the vehicle, so it doesn’t go inside.
- De-mist windows. Window deflectors can enhance your driving experience. In chilly weather, condensation can cause your windows to fog up, making it hard for you to see. Window deflectors prevent this from happening by demisting the windows. They also help minimize condensation in winter.
- Make your car more comfortable. Window visors deflect wind and rain away from your car’s windows. The interior becomes a more comfortable environment because outdoor elements don’t make their way in.
Types of Side Window Deflectors
These can be installed easily because they feature adhesive tape. The tape is fixed at the bottom, where the deflectors connect to the car’s windows. These visors divert rain better because they go outside the window channel. They push rain further away from your car’s windows. Their major upside is they don’t meet the windows at any point. But it can be challenging to remove them because they can damage the vehicle’s paint. When removing them, do it slowly and use a mild citrus-based cleaner to clean the residue.
These deflectors are a better option for car owners worried about their cars’ paint finish. They are secured by the window channels, so there is no adhesive to fret over. They look better and are less prone to damage compared to tape-on deflectors. They are also easier to remove, you only need to apply some force. However, it’s important that these deflectors fit your car perfectly, or they may rattle, loosen, and fall out. And since they are right next to the windows, they may scratch the glass if loose.
Auto Ventshade (AVS)
AVS was established in 1935 by Asa Phillips. It became popular because of its Ventshade car accessory. The metal device was installed above car windows and kept bad weather out and let fresh air in. It later led to the invention of Ventvisor and side window deflectors. In 1998, the company was acquired by Lund International. AVS also manufactures moonroof deflectors, light covers, and Aeroskin hood protectors. To understand why this company remains popular, get the Auto Ventshade In-Channel Ventvisor.

Side Window Deflectors Pricing
- $20-$50: Some of these side window deflectors are sold in sets while others are sold individually. They may be in-channel or tape-on deflectors.
- $50-$150: Here’s where you’ll find window deflectors made by big brands like Auto Ventshade, Nissan, Ford, and GM. Some are specially designed for specific car models.
Window deflectors can either be universal or custom-made. Universal rain guards are much more popular and are also affordable. However, they only last for a short period. Custom-made deflectors last longer, but they tend to be more expensive. Whether you decide to get universal or custom-made deflectors, confirm if they match your car windows’ curvature. If you get the wrong deflectors, you may have to keep adjusting them manually, increasing the tension in the plastic. At the slightest impact, they may get damaged.
It can be very frustrating to buy window visors only to find out they don’t fit your windows as they should. Some window deflectors are only designed for specific cars, so it’s up to you to do some due diligence before buying. Most manufacturers provide this information and you can reach out to those who don’t. How the rain guards will be installed further determines how well they will fit your car.
Since side window deflectors are installed on the outer part of a car, they should be tough and durable. They will be rained on, snowed on, baked by the sun, and hit by road debris as the vehicle moves. Choose window deflectors that are tough enough to withstand the elements and can ward off damage caused by UV rays. They should remain in place even after multiple car washes.
- Ease of Installation. Look for window visors that can be installed easily and quickly. They should also be long-lasting. Before installation, clean the deflectors and your car’s windows and leave them to dry. Then test-fit each of the pieces to find out which one goes where. Finally, install the deflectors.
- Deflector Shape. The shape of the rain guard determines which car it fits and the exact window it fits. The best side window deflectors have mounting seats that repeat the car windows’ curvature. Also check the deflector’s plane deviation angle because it can cause extra resistance as you drive, especially at high speeds. This may loosen the seal, and the deflector may get detached.
Best Side Window Deflectors Reviews & Recommendations 2021
- When washing your vehicle, take care not to damage or accidentally uninstall the side-window deflector, especially if it’s installed with adhesive tape. Use gentle detergents that won’t weaken the tape, and do not scrub the vent visor.
- If the color on your side-window visor starts to fade, consider using a trim restorer to restore the dark color of the plastic. It will also enhance its protection capabilities against UV rays.
- Consider hiring a professional to install the rain deflectors. Installing the deflectors at the wrong angle could cause you more problems, including rainwater being channeled into your car and constant hissing and whistling from the deflectors.
Q: Are side-window deflectors car wash safe?
A: It’s rare for a side-window deflector to come out during an automatic car wash, but it also depends on the quality of the product. If it’s made of tough acrylic material, then it can hold up to a car wash. You shouldn’t take them out every time you wash your car, since you might weaken the tape and deform the deflector.
Q: Do side-window deflectors keep the window clean?
A: The deflector doesn’t protect the window from dust or dirt, but it prevents droplets of rain and snow from falling into your car. It will mostly protect the top part of your window, and that’s why you can roll down the windows to a certain degree when it's raining. The wider the deflector, the more protection it offers.
Q: Are all side-window deflectors universal?
A: Unlike most car accessories, side-window deflectors are designed to fit specific car years, makes, and models. They are not made as universal fits, since cars come with different door shapes and sizes, and it’s hard to get one that fits all.
Our top pick is the Auto Ventshade Side Window Deflector. It offers OEM-quality performance and keeps you effectively protected from rain, snow, and harmful UV rays as you drive. It also minimizes wind noise to promote a more relaxing ride.
