Why is traffic pollution dangerous?
When a car drives, it burns fuel. The result of this combustion is carbon monoxide. This gas is hazardous to humans, especially in large quantities and confined spaces. While dangerous levels of carbon monoxide are rare if you live in small towns or far from roadways, it can really build up in urban settings. Traffic congestion can increase vehicle emissions in an area, which only serves to destroy air quality. Instead of nice clean air, motorists or folks in their homes have to breathe in these toxic fumes. This can lead to the development of asthma, breathing issues, pneumonia, cancer, or even, eventually, death. This is precisely why an air purifier is such an important purchase.
Features to consider when choosing an air purifier for traffic pollution

In this section, we will take you through all of the key details you need to remember to find the perfect air purifier for cleaning up any traffic pollution that finds its way into your home or car.
Coverage area
The very first thing that you will want to figure out is where you intend to use your new purifier and how big of a coverage area you need. If you are going to be using it in your car, then a smaller model will do the trick. If that is your wish, then the IQAir Atem Car Air Purifier is an excellent option. It is built with the interior of a vehicle in mind, making it an unobtrusive yet effective choice. On the other hand, if you want to purify your entire home, then the Medify Air MA-40-W is your best bet. It has a coverage area of up to 1600 feet, which makes it a good choice for a larger space.
Filtration system
Another important consideration is the type of filtration system that you want to employ in your new purifier. The general rule for filters is pretty straightforward: The more layers your filtration system has, the better off you will be. No filter makes this argument better than the Bluemyst Air Purifier. Its multiple layers work very well to clean everything from the air. Of course, these types of filters are more expensive to replace, which makes models like the Wynd Plus a good choice as well.
Speeds
Air purifiers operate through a fan ventilation system. As such, you can usually choose from different speed levels. Of course, higher speeds tend to make a bit more noise, so be careful if you are looking for a model for your bedroom. The NuWave OxyPure Air Purifier is going to be your best option if you are truly worried about finding the right speed level for different situations. This purifier has 6 different fan levels to choose from, making it a great all-situation type of purifier.
Timer
Something else to keep in mind is whether or not you want a purifier that runs on a timer. This would allow you to set the machine to turn on when you are not home so that your air would be nice and pure before you got there. This will help to save on electricity costs, as well as helping to extend the life of your filter.
Noise level

One of the most important factors in choosing a new air purifier is how loud it is when it is running. Obviously, you don’t want anything that is going to sound like an industrial fan, especially if you intend to run it in your bedroom while you are sleeping. Even when you are awake, you don’t want a model that is so loud you can’t hear anyone speaking or watch tv in peace. Even though the Medify Air MA-40-W is one of the more powerful purifiers on our list, it is also one of the quietest. The IQAir Atem Car Air Purifier is also designed to keep the noise level down.
Air quality indicator
You also want to look for a model that has an air quality sensor of some type. That way, you can easily see that it is running and working correctly, which will lead to much better air in your home or car. These sensors are usually very basic unless you decide to get one that can be run by an app over Wi-Fi.
Wi-Fi capability
Though it might seem like this is not something that you actually need to look for or think about with your new purifier, it is definitely something to keep in the back of your mind. An app will make it not only easier to control your device, which is a big plus, but it will also keep you up to date on your air quality and when your filtration system needs to be cleaned. If this is something that intrigues you, then the Wynd Plus, IQAir Atem Car Air Purifier, and the NuWave OxyPure Air Purifier are all great choices.
Dimensions and weight
Depending on where you are going to use your purifier, you need to keep the size and weight in mind. If you want to move the device from place to place with you throughout the day, obviously, you will want a smaller model. That way, you won’t break your back, transporting it around. The same is true if you want to use it in your car. On the other hand, if you are going to put your purifier in one spot and never move it again, the size won’t matter as much.
It is still a good idea to measure your space carefully so that you can be sure the model of your choice will fit correctly.
Warranty
Anytime you make a new purchase, whether it be for a fridge or an air purifier, it is always a good idea to look for a model with a good warranty. That way, you are covered should anything fail through the normal operation of your device. Of course, you need to make sure that you read through the warranty information as carefully as possible, as many companies will claim to offer a long warranty while only covering a short list of features.
