In 2017, it was found that the average commuter in the US spends about 42 hours a year stuck in traffic. That’s a lot of time to be spending inside a vehicle, and it is an important figure to note because of the potential build-up of toxic air inside of it.  Not many people know that cars have been dubbed as “boxes collecting toxic gases” by David King, a British scientist and adviser to the British Lung Foundation. When the car’s fans are on, it collects toxic fumes from all the other vehicles around it. With the car’s windows closed, these toxic fumes build up inside your car without you noticing.

Children, in particular, are at a risk of dangerous levels of air pollution because exposure to toxic air is far higher inside vehicles rather than outside. Since their lungs are still developing, exposure to these toxic gases makes them more prone to developing asthma and other respiratory conditions.

With people becoming more and more health conscious, car air purifiers have been rapidly gaining popularity among car owners everywhere. Car air purifiers function much like regular air purifiers but at a much lower scale. At a relatively inexpensive price, car air purifiers are able to eliminate airborne allergens, odors, prevent fatigue, and promote concentration while driving. Having a high quality car air purifier will definitely have you and your passengers breathing easy in no time.


Car air purifiers differ in the way they do their job. There are two common technologies that car air purifiers utilize: filtration and ionization. A car air purifier may use one or both of these methods at the same time to cleanse the air. Expensive air purifiers tend to use more technologies and have more features than cheaper ones.

Car air purifiers with a filtration system make use of one or more filters such as a pre-filter, HEPA filter, or carbon filter. They function much like your regular home air purifier but usually aren’t as effective. Basically, they pull in air from within your car, pass it through a filter or series of filters, and release clean air back out.

One the other hand, car air ionizers impart a negative electric charge to airborne particles like pollen, germs, and various other impurities. These negative ions are then attracted to surfaces, so that they are no longer airborne. Some air ionizers include a built-in surface to collect impurities, while others rely on the particles getting stuck to surfaces where they can be wiped up or vacuumed at a later time.

Sometimes, car air purifiers use both these technologies together to increase overall efficiency. However, like home air purifiers, these car air purifiers also need to be cleaned and maintained on a regular basis to remain effective. An air purifier with poorly maintained filters will lose its efficiency regardless of how powerful it may be. To keep your car air purifier in tip-top shape, it’s best to follow the manufacturer’s instructions on how often to clean or replace its filters.

When a car air purifier is properly used and taken care of, it will greatly benefit you and everyone else in your car. Now, let’s review the best car air purifiers you can purchase today.
