If your vehicle is starting to feel stale, or you’re noticing dust, allergens, and potential pollutants sneaking inside, you’re due for an in-cabin air filter replacement.

Best Car Air Purifiers: Reviews & Recommendations
Best Overall: Pure Enrichment PureZone Mini Portable Air Purifier
Multiple filtering methods with different power levels
Rechargable with 12 hours of run time
Weighs less than a pound
It makes noise while running
The Pure Enrichment PureZone Mini Portable Air Purifier is small and compact, but don’t let its size fool you. This is a powerful, effective, multi-stage car air purifier that’ll clean up your car’s interior air and allow you to breathe easier. Whether you’re hoping to fight pollutants, allergens, or odors, this little device can do it all — and it won’t take up much space or battery power. It’ll remove 99.97 percent of the dust, pollen, pet dander, smoke, and odors from your interior air. With an activated carbon pre-filter and a true HEPA filter, this small device is nicely effective. Plus, it offers four fan speeds so you can control how much filtering power you’re using. It’s lightweight at under one pound, and it includes a USB charging cable and a handle so you can stay powered up anywhere.
The only potential downside? You will hear some white noise as this car air purifier operates. Most people don’t mind it, though, as it’s pretty minimal.
Best Value: Pure Air Purifier Air Ionizer & Dual USB Charger
Removes odors from car interiors
No filter to change
Includes two USB charging sockets
It provides a fresher smelling interior but we wonder about purifying a big car's interior
This car air purifier is a great value buy, both because of its affordable price and its effectiveness when up and running. At under five inches in size, it is small — but it plugs right into your cigarette lighter socket, with no dangling cords, and uses ionization to clear your interior air. It releases 5.6 million negative ions to attach to positive ions in the air, weighing them down to eliminate them. This 12-volt purifier can get rid of odors, even tough ones like smoke and pet odors; it can also get rid of pet dander, dust, and other unwanted allergens or pollutants. And within 5-7 days, this little device can even eliminate stale scents lingering in cars with longtime odors.
However, do keep in mind that this car air purifier is very small. In larger cars, it can be a bit too small to offer complete coverage. And this device only operates when it’s plugged in and your car is on, so it won’t work when you’re out of your vehicle.
Honorable Mention: Philips GoPure GP5212 High Performance HEPA Air Purifier
Designed specifically for car pollutants
SelectFilter Plus technology removes 90 percent of airborne pollen
Removes more than 99 percent of airborne bacteria in one hour
Can operate slowly on its lowest settings
Does take up noticeable space
If you’re looking for seriously clean car air, you’ll like the power packed into the 7-by-7-inch Philips GoPure Car Air Purifier. This device, while larger than some options, packs a punch when it comes to eliminating allergens, bacteria, and viruses. But, because it’s specifically made for use in your car interior, it’s also able to remove pollutants like exhaust gasses coming from traffic. This car air purifier uses SelectFilter Plus filtration technology to remove 90 percent of airborne pollen allergens and more than 99 percent of airborne bacteria within an hour. And it can also handle toxic gasses like VOLCs and formaldehyde. Plus, it gets to work quickly; it features a Clean Air Delivery Rate of 16 m3/hour for PM2.5 particulates, meaning it can filter 50 percent of the air in a standard sedan in under 10 minutes.
You will notice that this car air purifier takes up some space. It can hang from your headrests or sit on your center console; either way, it is more noticeable than other, more compact products. Additionally, its lowest speed settings are the least efficient. However, on higher power, it’s a workhorse.
Most Versatile: Westinghouse 1804 Patented NCCO Technology Portable Air Purifier
Tackles bacteria, viruses, allergens, and pollutants
Can be used in your car or anywhere you take it
Up to eight hours of run time
Instruction manual doesn't make the purifier user friendly
You don’t have to leave your car air purifier behind when you’re not on the road — with the Westinghouse Portable Air Purifier with HEPA Filter, you can easily carry it anywhere. This compact device features a convenient handle, weighs just two pounds, and is powered by a rechargeable battery so it can go from car to hotel to house and anywhere else it’s needed. It cleans up your car’s interior air using medical-grade patented NCCO technology, which breaks down gaseous pollutants like VOCs, smoke, and odors plus viruses, bacteria, and allergens. And the three-stage filtration process also includes an oxygen generator and a true HEPA filter for a seriously thorough clean. You’ll have two filtration modes to choose from, and the purifier automatically shuts off after it runs for eight hours.
The only downside? This car air purifier’s manual is a rough read, and it’s tough to understand. Fortunately, the device itself is pretty easy to use and manage without it.
Best Smart Purifier: Wynd Essential Smart Personal Air Purifier
Fits in a car's cupholder
Runs for eight hours on a charge
Can be paired to your smartphone for monitoring activity
It isn't as powerful as some of the non-smart purifiers
Instead of settling for an average plug-in air purifier, you can get even more functionality by opting for the Wynd Essential Smart Personal Air Purifier. Sized to fit right into your car’s cup holders, this purifier is sleek and stays out of your way on the road. It’s designed by NASA and MIT engineers, with enough filtering power to remove 99.99 percent of air pollutants in less than 15 minutes, purifying 8 liters of air every second. It traps pollen, pet dander, dust, and pollutants in a medical-grade filter. And it’s super smart, too. It automatically adjusts itself to clean faster or slower based on local official air quality ratings. Plus, this purifier syncs with a smartphone app so you can remotely monitor your car’s air quality, control the device, and keep tabs on air quality trends.
The only potential problem area this car air purifier might present is its effectiveness. While it’s powerful and efficient enough for most individuals, those with serious allergy concerns may find it isn’t quite strong enough.
Best for Odors: IQAir Atem Car Portable HEPA Air Purifier
Three-stage particle and gaseous HyperHEPA filter
Includes easy-to-use car mount
Covers larger car interiors easily
Not the most powerful airflow
Airflow is directed towards backseat passengers
The IQAir Car HEPA Air Purifier is a different kind of car air purifier, as it’s designed to be mounted on the back of your seat headrests and provide a clean, allergen- and pollutant-free flow of air throughout the vehicle. And while it’s powerful at cleaning up particles 100 times smaller than 0.3 microns in size, it’s especially handy at combating odors, from sweat to smoke to lingering unwanted scents. This purifier uses a high-capacity centrifugal design paired with an exclusive HyperHEPA filter for ultrafine particles, and it can cover spaces up to 1,238 square feet in total, making it more effective for even the largest of cars and SUVs. And if you want more control, this air purifier also syncs with the Atem mobile app so you can customize the fan settings and activate a child lock.
The only complaint reviewers highlight is a lack of strong airflow coming from the device. While you can change the speed settings, it doesn’t generate a lot of air or a very noticeable breeze, if that’s something you’re hoping for.
Our Verdict on the Best Car Air Purifiers
The Pure Enrichment PureZone Mini Portable Air Purifier is a top car air purifier pick because it’s perfectly portable, easy to keep inside your vehicle, and offers plenty of power. It can tackle all different types of air woes, from allergens to odors to exhaust. But if value is important, you can also consider the Pure Car Air Purifier Air Ionizer & Dual USB Charger a small and barely-noticeable option that cleanses on a budget.
You’ve got questions. The Drive has answers.
Q: How long does a car air purifier last?
A: It really depends on how, exactly, the air purifier is designed. Some use HEPA filters that need to be swapped out and replaced every so often; others need to be “recharged” or cleaned, like charcoal or washable filters. Check the owners’ manual on your exact model to determine how long its purifying power will last.
Q: Can you leave a car air purifier running?
A: This, too, depends on the kind of purifier you’re working with. Electronic products typically feature automatic shut-offs, while those that work when plugged into your cigarette lighter will turn off once unplugged. Others that don’t require any kind of power, such as natural charcoal filters, won’t need to be handled at all.
Q: Can air purifiers fight odors?
A: Yes! Because odors are molecular within the air, most air purifiers can eliminate odors. Unlike chemical products that simply mask odors, your typical car purifier can get rid of the source, whether that’s through filtering, ionization, or another method.
