Car Air Purifier – Does it really help you breathe clean air?

Research study reveals that the air inside our cars and trucks is 15 times worse than the air a few meters from the automobile. When you think that traffic on roadways has considerably increased globally over the previous few years, this is bad news.

Most people never ever consider the air quality inside their vehicles, but it is a topic that bears some attention. On average, we spend about 5.5 percent of our time in our cars, according to one research study on the air quality inside vehicle cabins, which is a significant amount of time to seal yourself in with some quite bad air.

Yes, many modern cars have air filters in their HVAC system that brings in fresh, clean air from outside. But these filters can’t block ultrafine toxins or remove cabin smells and volatile organic compounds (VOCs).

Sources of Air Pollution in a Car

There are numerous factors for poor air quality in a car. Here is a list of the most typical sources of pollution you may experience in your car:

  • Smells
  • Cigarette smoke
  • Carbon Monoxide and exhaust fumes from other cars
  • Carbon Dioxide
  • Pet Dander
  • Particles matter like dust, mold, pollen, and germs
  • fine particles from brake wear, tire wear, road surface wear, and more
  • volatile organic compounds (VOCs) that are released by materials such as rubber, plastic, foam, and leather.

Methods to Clean the Air

There are 3 main techniques to clean up the air in any environment. This applies to a house, the workplace, or your vehicle.

Source control – eliminate the source of contamination. In an automobile, this can be tough because you don’t have an option besides driving on the road.

Ventilation – This is accomplished by distributing air from the outdoors or by rolling down the windows. Once again, this can be tough relying on the weather conditions or contamination on the roads.

Air Cleaning – using an air filter or air purifier to eliminate the contaminants.

Types Of Car Air Filters, Purifiers, and Ionizers

There are a few types of air filters and cleansers that you can get for an automobile, consisting of:

Engine air filters: These filter the air that enters into the engine for combustion. They have nothing to do with the air quality inside the traveler compartment.

Cabin air filters: These filter the air that comes into your vehicle when the heating, ventilation, and cooling (HVAC) system is set to attract fresh air. They may also filter the air that is recirculated.

Car air purifiers and ionizers: These are electronic devices that are usually plugged into the cigarette lighter socket. SOme purifiers use HEPA filtration system and actually clean the air inside the car. Ionizers operate on the concept of ionizing pollutants and causing them to stick to surfaces where you will not have the ability to inhale them.

Ozone generators: These devices create ozone, efficiently damaging the molecular structure of toxins and unpleasant fragrances.

Each of these filters uses a particular method to perform a different function.

Engine air filters

Engine air filters utilize a filtration media that is typically paper or cloth-based to trap particles and debris and prevent them from entering the engine’s intake system. Unlike cabin air filters, engine air filters have nothing to do with the air inside the traveler compartment of a cars and truck.

Cabin air filters

Cabin air filters are an important part of maintaining an irritant and odor-free traveler compartment. Whereas older cars attracted fresh air through unobstructed outside vents, newer vehicles utilize cabin air filters to trap particles and particles. 2 types of cabin air filters may help in reducing the allergens and odors in your automobile:

HEPA cabin air filters: These filters utilize a fine mesh to trap large particles, like pet dander, and small particles, like those found in tobacco smoke.

Cabin air filters with triggered carbon: Filters with activated carbon are specifically good at getting rid of smells.

Even when you set the HVAC controls to recirculate, the cabin air filter is still in play in a lot of cars. This setting avoids new air from getting in the vehicle. It just recirculates the air in the cabin, so it can effectively prevent the intro of brand-new contaminants while removing existing contaminants.

Cabin air filters work much better than ionizers, however you require to change them frequently.

Some cars, particularly older cars, don’t have cabin air filters. And some older vehicles that do have cabin air filters have them placed in a location where they can not filter air as it recirculates inside the cabin.

If your vehicle has a cabin air filter efficient in filtering recirculated air, frequently setting up a fresh HEPA or carbon-impregnated filter is the best method to improve the air quality inside your car.

Not all modern-day vehicles have an effective filtration system with a HEPA filter. Exposing yourself to toxins will contribute to asthma and allergic reactions. You might find a portable purifier with a HEPA filter. This will be a deserving investment if you or a family member suffers from asthma or allergic reactions.

Car air purifiers and ionizers

HEPA air purifier systems pass air through small physical filters that collect dust, irritants, pet dander, and the majority of other airborne contaminants. After flowing through the system, it pushes out the clean air. With HEPA air purifier systems, you will sometimes need to replace the filter, depending upon how long the device runs and its size.

Air ionizers developed for automobile usage are normally compact units that plug into a cigarette lighter socket. Instead of filtering the air, these devices give off ions, which are molecules that have a positive or negative charge instead of the regular neutral charge.

The basic idea behind a car air ionizer is that ionized particles of numerous irritants and odorous products will either stick to surfaces or each other. At this moment, they won’t be floating in the air any longer.

Although a good air ionizer must do what it is created to, it won’t filter anything, and you might find yourself dealing with a dark coat of dust, pollen, and whatever else holding on to every surface inside your vehicle.

The other issue to keep an eye out for is that many of the small, weak ionizers that plug into a cigarette lighter are too anemic even to accomplish that much.

Ozone Generators

Like ionizers, an ozone generator doesn’t filter the air. It generates ozone, which engages with various odor-causing chemical substances, typically rendering them odorless. For some sources of bad vehicle smells, this works rather well.

Note that ozone can be potentially dangerous to your health, so I do not actually recommend using them.

The EPA has actually reported there is a variety of health effects related to high levels of ozone. This may consist of decreased lung function, throat irritation, extreme asthma symptoms, cough, chest pain, shortness of breath, inflammation of lung tissue, and a greater level of sensitivity to breathing infection.

The Most Important Features to Consider when buying portable air purifiers for your car


Our preference is for car air purifiers to carry triple-level purification to capture 99.97% of irritants and a favorable square footage rating that goes beyond the total vehicle space for finest outcomes. A 3-stage filtration system ought to include at least a HEPA filter and triggered charcoal filter with an optional ionizer to work extra in binding and ground impurities for easy elimination.


Opt for car air purifiers that are cigarette lighter or adapter suitable, dealing with USBs. This will allow it to run forever in your lorry without worrying about recharging times. In addition, focus on digital bonuses such as real-time air quality monitoring using color-coded LEDs or Bluetooth/WiFi app compatibility. This gives users a real sense of air quality on the fly.

We enjoy car air purifiers that can be installed horizontally, vertically, on dashboards, and behind seat headrests. Just as essential is its airflow setup, with a nod to the round 360-degree air intake for more even circulation of intake and airflow to reach the entire vehicle interior.

Are air purifiers truly worth it?

Yes, we feel air purifiers are absolutely worth it.

Ion technology and ionizers do a remarkable job of reducing the effects of and grounding air-borne contaminants, making the air a lot easier to breathe.

Many cleansers include a USB power cord. To power the system, you can use a USB car battery charger. Some car air purifiers include a 12V car and truck power adapter so that you can link directly into the 12V vehicle power outlet.

You can now equip your vehicle with the very best HEPA car air purifier that comes with an effective motor covering more than 100 cubic feet of the cabin. Thanks to improved innovation, car air purifiers are now USB-powered.

Tips & Advice

  • Routinely check your filters when you have a system that requires changing them out. You’ll wish to make sure your air filtration system is running as it should. Checking the filters will offer you a great estimate of the time between filter modifications.
  • It’s best practice to not have your purifier on while the windows are down. Irritants, dust, and germs can build up a lot quicker in your filters.



It is not suggested to recycle any filter for in-car air purification systems. The filters are non-reusable and only planned to last a certain quantity of time. Using it more than as soon as can impact the quality of the air, in a negative method. Some makers won’t even let you reuse a filter.


Leaving the filters in the device for too long might lead to really poor air quality. The allergens, hair, and other things won’t go through the maker as meant, leaving the majority of what the purifier is supposed to capture still drifting around.


While your car air filter does an excellent job at cleaning the outdoor air as it enters into the cabin of the car, it may not eliminate odors and other small germs and allergen. In-car air purification systems can eliminate more than simply dust and smog from the outside.


Most car air purifiers have an automated shut-off time. Considering that most of car air purifiers are linked to your battery, they will shut off as soon as the vehicle is turned off. With (AA or AAA) battery-operated car air purifiers, it could be a different story. You may want to check if they are on a timer or if you have to by hand shut them off prior to purchasing a battery-operated cleanser.


The best car air purifier is a worthwhile investment. They play a vital function when outdoor traffic contamination is high, and you can not open the windows.

A standard house air purifier can not fit in a cup holder or sit on your car dashboard. This is due to the fact that they are large in size. Car air purifiers can be found in a smooth, modern-day style. They are compact however effective.
