If you tend to spend a lot of your time in the car or on the road, there are some items you need to ensure that you have inside that will be able to make your experience as enjoyable as possible. One of them is a car air purifier. As you’re out and about, you’re bound to come across areas where the outdoor air is not as breathable as you’d like it to be, and it is in these kinds of situations that a car air purifier might be handy to have. If you don’t have the time to search for the best air purifier around, then the Autowit Fresh 2 car air humidifier purifier would be a good option to default to. Stick around, and we’ll go through a number of reasons why it could be the best car air purifier for you.

Why We Like It – Autowit Car Air Purifier

The Autowit Car Air Purifier is a small yet reliable tool that you can use to ensure that the air quality of the air you’re breathing is up to scratch and free from any allergens or foreign elements.

  • Includes a humidifier
  • Has a silent mode for noise-free operation
  • Powered by USB
  • No onboard battery


Similar to the Airthereal ADH80, the Autowit car air purifier boasts a 3 stage filtration process that makes it a decent choice, especially if you’re looking for something that effectively filters the air around your car. It’s got a composite nanosilver that kills bacteria, a Hepa filter that eliminates allergens, and an activated carbon filter that does away with bad odors. It’s not as small as the IQAir Atem car air purifier, but on the other hand, it does feature a humidifier function, unlike the IQAir Atem.


Unlike the Figo ThinkGA car ionizer air purifier, the Autowit Car Air purifier is powered through a USB input and is pretty much easy to keep on. All you need is a USB port that you can plug it into, and you’ll be all set. It only requires 5 Volts of power to function, and can be categorized as relatively energy sufficient. If you’d rather have a battery-powered air purifier, the Wynd Plus Smart Personal Air Purifier could be a worthwhile option. But if what you need is an energy-efficient air purifier, then the Alexapure Breeze is what you need.


With a room coverage of approximately 86 square feet, the Autowit Car air purifier has just enough reach to ensure that you enjoy fresh air throughout your vehicle’s interior, and with the air quality indicator that’s also on board, you’ll always have a general idea of how clean the air in your car happens to be. The indicator is something that it has in common with the PHILIPS GoPure Compact 200, but everything else, from form factor to functioning, is quite different. For those that’d prefer a more personal air purifier, then it may be worth checking out AVICHE Necklace Wearable Mini, a wearable purifier.

To make sure that the Autowit air purifier always operates at optimum functioning, you’re advised to replace its HEPA filter after every 3 to 4 months, but if you tend to spend a lot of your time in areas where there’s high-level air pollution, then the frequency might jump to ever 2 to 3 months. Like a lot of the air purifiers in its price bracket, the Autowit Car Air purifier is backed by a 1-year warranty, so you shouldn’t hesitate to reach out to their customer care team in case you come across any problems with your unit. For a truly durable unit, however, you’ll want to read our Alen Breathesmart Flex air purifier review.


Everybody needs to be able to enjoy fresh air whether indoors or out and about, and the Autowit Car Air Purifier provides the opportunity to do just that. Its air filtration process eliminates up to 99.7% of allergens from the air, making it safe to breathe, and preventing the onset of any respiratory diseases.
