There is so much pollution in the air nowadays that many people find it increasingly difficult to breathe whenever they’re at home or outside. This is why many individuals are now resorting to purchasing an air purifier not only for their homes, but also for their cars. As you would expect, a car air purifier is a lot different in terms of form when compared to home air purifiers, but functionality is pretty similar. The Homdox car air purifier for example, features HEPA filtration as well as an activated carbon filter like most home filters do, so it can be argued that it’s just as efficient. While it might not be one of the top-rated air purifiers around, does it have what it takes to be considered the best car air purifier? Let’s find out.

Why We Like It – Homdox Car Air Purifier

The Homdox Car Air Purifier uses 3 stage filtration to get rid of any kind of impurities within your car’s interior, so that you get to enjoy clean air whenever you’re moving around. It’s got a true HEPA filter to facilitate this function and a carbon filter to eliminate any bad odors.

  • Air Quality Indicator
  • Ultra-Quiet Operation
  • Activated Carbon Filter to get rid of bad odors
  • No filter replacement indicator


Unlike the GermGuardian AC5250PT, the Homdox car air purifier is guaranteed to improve your car’s air quality thanks to its 3-stage filtration process. Foreign particles up to 0.3 microns in size get eliminated from the air when it gets through a true HEPA air filter, including pet dander, plant pollens, and a whole lot more. Its activated carbon filter also helps air filtration since it eliminates any bad odors, leaving your car’s interior with a nice fresh smell. If you’d want to enjoy even cleaner air, we suggest looking into the IQAir Atem car air purifier, as it has got a Hyper HEPA plus air filter that gets rid of particles as small as 0.003 microns.

To get the Homdox car air purifier working, all you have to do is hook it up to the 12/24 Volt cigarette adapter in your car, and once you’ve done so, all you’ll have to do to switch it on is turn your car on. The cigarette adapter sedan air freshener also boasts ultra-quiet operation, as you can only expect it to produce between 40 and 55 decibels of sound when switched on.


To keep you aware of the air quality that you might be breathing, the Homdox travel USB auto air purifier has got an integrated air quality sensor that is color-coded and relays the status of the air through 3 colors. Green means good quality, orange, moderate, and red, poor. On the other hand, the Wynd Plus Smart Personal Air Purifier will relay this information through an app. It’s definitely easy to move, unlike the Honeywell True HEPA air purifier, which weighs 21 pounds.


To ensure efficient operation, you will have to replace the air purifier’s true HEPA filter after every 6 to 8 months of use. Every time you change it, you’ll have to keep track because, unlike the PHILIPS GoPure Compact 200, there’s no check filter indicator on the unit, so you’d be better off keeping track of when you last changed the filter. This is why it’s important to know if air purifiers really work.

There’s a lot of value in having a sedan air freshener remove all the impurities in your car’s air, as this will make you feel better as you travel, and even improve your overall mood. The true HEPA travel USB auto air cleaner can also be used in your office, small bedroom, pet room, or even your living room, since all you need to do is place it in an open area and have its power connected to a source.
