How to Buy the Best Car Air Purifiers

How To Buy The Best Car Air Purifiers

There are different methods of purifying the air inside a car and so, different manufacturers take different approaches in making their products. This often leads to confusion for those buying a car air purifier for the first time.

To get a better understanding of these devices and be able to make an informed and better decision, the following buying guide list all the major features to look out for.

1. Types of Car Air Purifiers

The first thing you'll need to understand about car air purifiers is that they use different technologies, which has given rise to three major types.

They are ionizers, ozone generators, and HEPA filters. Following is a closer look at each type.

Ionizers. As their name suggests, ionizers work with tiny ions, charged particles that the eyes can't see, but which are effective in making changes at a molecular level.

Here, the devices release anions into the air. Anions are negatively charged ions and will naturally try to interact with any and everything that has a positive charge. In this way, many particles get neutralized.

The downside of ionizers is that they only neutralize about 30% of airborne particles, so they are not 100% effective. On the plus side, they need little maintenance and no filter changes.

Ozone Generators. This type of air purifiers is highly effective in eliminating odors and killing off bacteria and other microorganisms without needing a filter.

It works by releasing three oxygen molecules into the air as ionizers do. This three-molecule oxygen is a very effective air purifier but it's also a heavy lung irritant, making it unsafe for residential use.

HEPA Filters. HEPA stands for High-Efficiency Particulate Air filtration and it's considered the gold standard when it comes to filtering air. As the name suggests, HEPA devices use highly-dense filters to remove 99% of particles.

It relies on sucking air and passing it through the filter and you'll also need to change the filter from time to time. Asides from that anyway, it's the best type of air filter that you can get for your car.

You'll also find some devices that combine ionizers and HEPA filters and this makes them more effective. You can go for them if you want to but just keep away from any ozone-emitting device.

2. Placement

This is a decision that you'll have to reach by yourself because only you know the space you've got available in your car and the type and size of an air purifier that might fit in.

3. Noise & Settings

Air purifiers aren't normally loud, but some are quieter than others. So, if you care about noise and want as little of it as possible, you'll need to keep an eye out for an air purifier's noise levels.

This is important if you like listening to the radio while driving for instance, or for other reasons, where silence is of major importance.

4. Extras & Attachments

Some car air purifiers come with extra features that might be valuable to you, so you need to check every potential purifier that you want to buy.

This might include purifying systems combinations for improved efficiency or smartphone app additions for monitoring or control of the device.

5. Air Quality Indication

This is one of the most important extra features that a car air purifier can come with, but it's not available in every device, so it's left for you to check for it if you need it.

An air quality indicator is a sensor that checks the air's quality inside your vehicle's cabin and informs you of it. Most devices use simple LED lights with for instance Green for good, Red for bad, and Blue or Yellow for okay.

6. Maintenance, Cost & Ease of Use

You'll also need to decide what's best for you by choosing between a filtering system that costs more, needs more work, but also filters more and an ionizer system that costs less and needs almost zero maintenance, but is also less effective.


We've come to the end of this car air purifiers review and you've seen all the different offers out there, from the very affordable cigarette-lighter port ionizers to the more pristine air filters.

It's left for you now to make your choice because it's only you that knows what will best fit into your ride, as well as your budget for it.
