How to Choose Good Car Air Purifier

Size and Mounting Option

Choose a size that fits your car. Its design should make it easy and stable to install. Besides, pay attention to the mounting style. Also, compare the car interior space and the maximum area the air purifier can clean.

Filtration Technique

Several studies published by the CDC and NCBI suggest that HEPA filters are effective in air purification. So an air purifier that at least has a HEPA filter stage seems like a better choice.

For better odor removal, the activated carbon filtration stage is also necessary. Thus a three-stage air purifier looks promising.

Noise Level

The equipment that runs quietly is ideal. So check on the noise level and ensure you can tolerate it. Moreover, a system with multiple fan speed makes a better choice.


For ease of use, the air purifier should be compatible with the cigarette lighter or an adapter. Besides, it’s convenient if it has a USB power outlet port. That way, you can keep the device running and charge your smartphone at the same time.


Do I Need a Car Air Purifier?

Most if not all cars have cabin air filters. However, they’re less effective on ultra-fine particles and dust mites (for example, 0.3 microns size).

Besides, as you open the door and windows frequently, the non-filtered air rushes in. A portable car purifier thus helps to remove undesired odor, smoke, dust particles, and other allergens.

How Often Should I Replace the Air Filter?

It depends from brand to brand. But when the effectiveness of the device has dropped considerably, consider changing the filters.

Some air purifiers require filter replacement after 4, 6, or 12 months. So consult your manual. Also, some brands display warning when it’s time to change the filter.

And we spend a significant amount of time in the car daily. That’s why we offer you the top 10 car air purifiers to try out. Your car interior deserves to be clean and allergen-free.
