How We Rated The Car Air Purifiers

As well as testing a number of purifiers of filtration and ionizer types, we also based our recommendations upon a number of factors. The factors that we rated the purifiers from included their purification method, inclusion of air quality indicators, additional accessories and value for money. These are all important factors that determine the quality of a purifier and how it will perform when used inside of your car.

Car Air Purifier Buying Guide

An air purifier for cars can come in all shapes and sizes and include different filtration methods that include HEPA filters to Ionizers. Considering the majority of us spend a lot of time in our cars, the importance of clean air is just as important as it is at home. Benefits of car air purifiers include no tobacco smoke smells, no mechanical smells from the car, removal of allergens and bacteria as well as many other benefits.

To help you make an informed buying decision, we have produced the below guide regarding car air purifiers.

Sources of Air Pollution Inside The Car

Many people simply don’t see the benefits of using a car air purifier. However, by understanding the pollution that enters the car, you may be able to see their uses.

For example, if you like to drive with the windows down, particles will enter the car, which can come in the form of dust, pollen, fumes and more. Poor smells due to odors can also be eliminated with an air purifier, which can make driving inside your car far more pleasurable.

Ionizer vs Filters

Ionizers trap airborne particles and use electrons that are released from the device to attach to the air molecules. These electrons then form ions that attract harmful particles and bad odors. This process cleans the air within your car and removes any harmful allergens.

A filter type of purifier such as the Phillips GoPure Compact 200 uses multiple filters, where the first filtration stage captures large particles. The second filter, which is normally the HEPA filter removes dust and other harmful particles. Many purifiers also include a third step, which includes a HESA filter that removes bad odors such as smoke from cigarettes. This is usually only found within the premium models such as the Phillips model.


Due to the sizes and connectors that come with most car air purifiers, you may notice that many are placed in different areas of the car. For example, many connect straight into the 12V cigarette lighter, whereas others are left in cup holders or even mounted with suction cups elsewhere in the car.

Ease of Use and Maintenance

The best car air purifier devices can be switched on with a single button or automatically when it senses the air quality is bad. You should avoid any that require long winded setups or require multiple cables for powering up the device.

To ensure the purifier operates to the best of its abilities, you will need to maintain it. This can involve removing debris such as dust, pollen and other particles with a car vacuum cleaner. You may even be able to clean it using plain water but this will be stated by the manufacturer.

Air Quality Indicator

A premium feature found on some of the more expensive purifiers is an air quality indicator. They are able to automatically take samples of the air and then determine the quality of the air inside of the car. The purifier will provide feedback of the air quality using LED indicators on the device and may even automatically switch on or off to resolve the poor air quality.


Investing into a quality car air purifier will ensure that the air you are breathing in whilst driving is clean. Some people suffer from bad air particles more than others and investing that little bit extra for multiple layers of air purification is highly advised.

All of our recommendations cover a range of different types of purifiers that are suitable for all budgets. To avoid disappointment, we strongly recommend buying from a reputable brand as they are more than likely going to provide better purification results.
