Air purifiers are very common in households these days, but the health benefits on offer and convenience make them ideal for sticking in a vehicle also. Your car may be full of unseen microorganisms, dust, smoke, and other nasty particles that could expose you and your passengers to potentially serious health issues. However, you can’t just take an air purifier from your home and put it in your car, as they don’t tend to work the same way, and usually don’t have the same type of power hookup.
Special vehicle designed purifiers can fit right into your cup holders or sit out of the way in your car’s cigarette lighter socket. With different purification methods and a range of different sizes available, we’ve selected our 5 top air purifiers for cars underneath.

Air Purifier for Cars Buying Considerations
Air Purification Method
There are presently three methods of air purification for use in vehicles. These types of filters are broken down into three categories, which are filters, ionizers, and ozone generators.
These draw cabin air into the unit and separate microscopic particles from the air. Then the air is sent back into circulation. The best filters for use in these units are HEPA filters and nanocarbon filters, which will trap a vast majority of even the smallest particles.
They don’t draw in air to clean and circulate. Instead, these types of purifiers release a constant stream of negatively-charged particles, called anions, into the air. These anions interact with every surface in your car that has come in contact with positively-charged ions and neutralizes them. As it neutralizes the particles, your air becomes cleaner and fresher. These filters may generate some ozone, but it is typically not enough to negatively impact the localized environment.
They are especially great for neutralizing strong odors. Ozone generators do have a drawback though, in that they produce three molecules of ozone to help neutralize even the most offensive odors. Ozone can have negative effects on the human body if you’re exposed to it chronically, so it may be best for most people to avoid using an ozone generator in their car.
Maintenance of the Filter
Car air purifiers generally require some maintenance, which can include cleaning and replacing the filter of the purifier. You’ll want to use a filter replacement made by or recommended by your purifier’s manufacturer, so keep that in mind. If you’re using an ionizer that does not have a filter, you don’t have to worry about replacing a filter. But you do still have to keep the unit clean, so keep that in mind.
There are regulations worldwide concerning the generation of ozone in air purifiers. That is because there are concerns over the dangers of ozone generation.
Ozone is a molecule that’s extremely effective at reacting with and eliminating airborne chemicals and strong odors. Ozone has a natural, fresh scent to it and is incredibly effective at killing mould and mildew spores and particles.
However, if it’s present enough to eliminate particularly strong and pungent odors, then it will also react to your skin, eyes, lungs, and any other exposed areas. Ozone is essentially an unstable oxygen molecule, so wherever oxygen can reach, ozone can as well. It can cause long-term damage if you are routinely exposed to an ozone-affected environment.
When looking for an air purifier for your vehicle, check and see if the filter produces any ozone, and if it does, make sure that it is within regulated, safe levels.
