Buyers Guide

Now, let’s look at what you need to know to be able to pick out a good car air purifier for yourself:


Due to the sizes and connectors that come with most car air purifiers, you will notice that many get placed in different car areas.

For example, many connect straight into the 12V cigarette lighter, whereas others get left in cup holders, and some get mounted with suction cups anywhere in the car.

Ionization vs. filtration vs. both

Car air purifiers tend to come in three different varieties: those that purify the air through ionization, those that purify the air through a filtering system, and those that use a combination of both filters and ionization. There are pros and cons to all models, and none are better than the others; it just depends on what you’re looking for.

Type of filters 

Many air purifiers have a pre-filter stage, which collects larger dust and debris, then a charcoal filter removes toxins, and then often a HEPA filter. HEPA stands for “high-efficiency particle air,” which means it’s a filter meant to trap very small particles from the air. HEPA-like filters can do a very good job of purifying the air. Still, true HEPA filters can capture particles as small as 0.3 microns and scent molecules, helping contribute to a healthier environment.

Several negative ions per cm³

Negative ions are typically measured per cubic centimeter. Healthy, outdoor environments tend to have high negative ions, anywhere from 2,000 to 4,000 negative ions per cm3 and lower ozone and pollutants levels. So, most ionic purifiers aim to add negative ions to your space and lower pollutant levels.


We all hope that there’s never any need to use a warranty for any of our purchases, but the truth is nothing lasts forever. Some air purifiers have longer life spans than others, and of course, sometimes accidents happen.


Investing in a quality car air purifier will ensure that the air you breathe while driving is clean. All of our recommendations cover a range of different types of purifiers that are suitable for all budgets. Not only do they eliminate allergens, germs, and bad air particles, but they also the car smell better.
