Best Side Window Deflectors: Enjoy Fresh Air All Year Round

Grab two or four pieces of these vent visors to enhance your vehicle’s functionality. They are tinted and can fit a variety of vehicles. They are also strong and flexible and are designed to blend with your car’s contours. The deflectors minimize heat buildup in parked vehicles as you can open the windows slightly, especially if you aren’t going very far. They divert rain and wind and allow fresh air to circulate naturally.

Auto Ventshade gives a limited lifetime warranty for these rain guards, so you can be sure they are built to last. You can install them in minutes without drilling or using any special hardware. The manufacturer provides an installation guide that makes installation a breeze. These are in-channel vent visors and connect to the windows’ rubber seals using 3M pre-applied automotive tape. They can also be fitted directly to the window channels.

Made from reinforced acrylic, these window deflectors are precision-engineered to resist scratches and UV rays. They can also go through car washes without falling out.

However, you have to be careful when installing them as they may crack or break. They are also susceptible to scratches.

Auto Ventshade produces the best vent visors for all types of vehicles, from SUVs to trucks. All of the company’s window deflectors come with a limited lifetime warranty, so quality is guaranteed. These deflectors fit perfectly, last longer, and endure everyday use. They are thick, strong, and flexible. They also have a smoky color that does not fade with time.

The chrome-plated finish of these rain guards corresponds with the chrome trim on some vehicles. It increases the deflectors’ durability and also enhances your car’s appearance. The rain guards allow fresh air to circulate, eliminating stale air and keeping your car’s interior cool. They are easy to install because there is no drilling required. Like our top pick, these deflectors feature 3M pre-applied adhesive tape which allows you to install them easily.

The main drawback is that they leave a small space between them and the windows, which results in restricted airflow. Additionally, they make a whistling sound when you drive because of their proximity to the windows.

Ideal for Jeeps and other off-road vehicles, these window visors will fit your 4x4 perfectly. They are also ideal for 2016-2019 Toyota Tacoma double cabs. They push in fresh air while deflecting rain and wind away from your car. Their minimalistic design allows them to add a dash of style to any vehicle.

These rain guards are made from 2mm-thick smoked acrylic and will serve you for many years. The material makes them scratch-resistant and also shatter-resistant. To reduce wind noise as you drive, the deflectors direct wind to the top of your vehicle. They change your car’s aerodynamics and keep out snow, rain, dirt, and sleet. They make for a comfortable, quieter ride. The five-year warranty that Rugged Ridge provides will make you confident about your purchase.

However, the shortcoming of these rain guards is they are specifically designed for Jeeps and off-road vehicles and don’t fit other cars. Also, they may get deformed if you use them in very hot conditions.

Like the old saying goes—you can’t judge a book by its cover—the same can be said with Auto Ventshade’s window deflector. Yes, the brand is on our list twice already, and there is a good reason for that; the company knows how to make a high-quality deflector. The 194109 model stands out with its red-lipped design and in-channel attachment.

The kit comes as a four-piece set that installs easily and firmly in the slots of the windows. Each window deflector is tinted and reinforced with acrylic that is UV- and scratch-resistant. Plus, they are all safe to be used in the car wash.

There have been complaints with the installation directions. The way it describes may lead to a bit of rain leaking through the window seal. You may want to follow directions of those who have installed it before in order to keep it leak-free. You may also run into issues with installing it on certain trucks like Dodge Ram models.

For Subaru and Impreza drivers, there are even window deflection kits built for you. These side visors not only protect rain from dripping into the car when the window is open, but they also look great once installed. The kit includes a visor for the five-door models built between the years 2013 and 2015.

Another great thing about these visors is they are simple to install and can be done by one person. While the directions are included, you may have better luck watching a YouTube video to ensure a tight and secure fit. The visors are big and wide, allowing you to open the windows further while it is raining without soaking your arm or your seats. The visors hold tightly and work great through car washes and heavy downpours.

However, the directions can be a bit difficult to follow. Once again, stick with a YouTube video or website guide to fit them. You should also be careful when attaching the clips, as they are plastic and aren’t the most durable.

Auto Ventshade returns with its four-piece matte black window deflector kit. It’s a higher-priced version of the company's normal in-channel set and it looks great. Once it’s installed, it will blend in with your vehicle’s look while making it stand out from the rest of the pack. It will look like your vehicle just rolled off the factory line but with a little bit of extra flair.

The sleek-looking matte black finished vent visor allows fresh air inside the vehicle but prevents rain from seeping through. It also works well at reducing wind noise and resistance which can also cut down on any fog that might steam up your windows or mirrors. It installs easily and quickly without any extra hardware or tools.

It is a little pricey due to its matte black finish. There have also been issues with automatic windows rolling back down once it comes into contact with the visor. It may be an issue with the sensor and may only happen occasionally.

Goodyear is a name brand known for vehicle equipment and accessories. Its window deflectors are another great standard for high-quality products. While these are only built for Ford trucks, the Suprecrew in-channel visors are robust, sturdy, and designed to blend in with the windows.

Everything you need to install the visors is included in the pack, making for an easy and fast installation (around 20 minutes). If installed correctly, the deflectors fit securely, tightly, and make your truck stand out from the rest. 

The one thing you will notice about the visors is their high price. You may be paying for the Goodyear and Ford name as well, but you are still getting a high-quality item. They do come with rather detailed instructions that need to be followed to the letter in order for the visors to work as designed.

WeatherTech is another name tied with preventing any type of weather from entering and ruining your vehicle. These WeatherTech Side Window Deflectors are built for Toyota model vehicles, specifically Tundras. In total, the kit comes with four window deflectors: two for the front doors and two for the rear doors.

The wind visors are designed with a transparent tint so you can see through them. However, you run into the fact that they are set at a much higher price than our other honorable mentions. This is because they are built by WeatherTech and feature high-quality plastics and designs. They are thick, sturdy, and built to withstand downpours and reduce road sound.

Aside from their price, the deflectors may also fit a bit loosely on Tundras. They may also make a whining sound when rolling up the windows. This may have to do with any dust or dirt that gets caught between the plastic.
