What is a Car Air Purifier?

Car air purifiers stemmed from a need by asthmatics, to reduce the number of allergen attacks. Because nobody wants to breathe in germs and dirt, it’s no surprise that they have gained so much popularity. Clean oxygen only, thank you very much!

Purifers are not to be confused with car air fresheners. A freshener simply deodorizes, or masks smells floating in the air inside a car, whereas a purifier aims to filter and clean the air before it ever gets into the car in the first place.

There are different types of purifiers on the market; each one is made and works in a different way. Some use small amounts of ozone to clean the atmosphere, and others will use a true HEPA filter. Others will also use natural properties like charcoal to filter the air.

When driving, you subject yourself to all kinds of pollution. Whether it’s exhaust fumes from other vehicles or just a bad odor in general, a car air purifier will greatly reduce potentially harmful allergens.

Depending on what you’re looking to achieve, this product may not always be necessary, though. In some cases, you may just need to give your car a good clean from the inside.

Sources of Air Pollution

Air pollution is a mixture of solid particles and gasses that pollute the atmosphere.

It can build up in your car for any number of reasons, even if you don’t smoke in there or own any pets you have ride along with you (dander, anyone?). Simple things such as dust and exhaust fumes are common culprits.

This can cause a lot of issues while driving, especially if you suffer from asthma or other breathing problems – which puts both your safety, that of your passengers and everyone around you on the road at risk.

For more information on such pollution and how it can affect you, check out the Youtube video below.


Which Methods of Air Purification Do These Products Use?

We briefly mentioned above the different types available, and now we’ll go into more detail to help you make a decision as to which is the right product for your needs.

Purifiers are made in all sorts of different types and designs, and components change from product to product. Here are the most common ones you’ll come across.

Car-Air Ionizer

This type works by releasing a negative ion charge into the air, and it doesn’t use a filter. The negatively charged ions attach to the harmful particles and bring them to the surface, so they are easier to clean.

They typically emit small amounts of ozone, essentially to give your car a “shock” and eliminate most toxins and pollutants. If you’re based in California, these may not be available to you as this state has heavily regulated ozone-emitting devices.

These are usually very small and plug right into the 12-volt power socket. They don’t require much power at all either, so they’re really low maintenance.

Ionizers are especially effective if you need to get rid of smoke odors inside your car or other persistent smells from your car’s interior.

HEPA and HESA Filters

HEPA filters tend to be the most common type. They’re made up of a lot of tiny glass fibers, and once the fibers are formed, they’re made into mats and then manipulated into an accordion pattern.

They are then put into a case and are ready to filter particles through in order to clean the area. These filters are good for catching particles, but are not recommended for gas removal, as gas will pass right through the coils.

On the other hand, HESA stands for high-efficiency specific air filter, and these filters are meant to take care of strong odors and gasses that a HEPA filter can’t remove.

These filters are best for people with allergies, since they will capture most allergens.

Activated Carbon Generator

As the name suggests, these filtration systems contain activated charcoal, which is a natural way to reduce toxins. Activated charcoal is used in all types of products ranging from car air purifiers to face masks.

Activated charcoal is like a magnet for toxins and other chemicals in the atmosphere, like benzene and formaldehyde. It works to pull all of those unwelcome visitors away from the source to leave the area much cleaner.

Activated carbon generators are best for removing harmful gasses and their odors from the air in your vehicle. These are particularly effective because they capture small particles that other filtration systems might miss.

Air Freshener

While these aren’t technically air purifiers, they’re still a good option to consider if you want a particular scent in your ride. Perhaps you forgot food in your car for some time, and were left with a delightful smell?

In these cases you don’t really need something to purify the air, you just need something to get it to smell fresh.

Utilize them after you’ve used a car air purifier to get rid of any unwanted pollutants, since air fresheners only work to mask the odor and are not an effective solution on their own.

What Should I Look For In A Car Air Purifier?

How Loud Is It?

If it’s noisy when in use, this can be a major distraction to you on the road.

If you’re trying to listen to your favorite radio station, you’re probably going to be pretty annoyed if you can’t hear it all that well. Even worse, if you’re one to be easily distracted, this might put your safety (and that of others with/around you at the time) at risk.

So, you’ll want to be sure to choose one that isn’t going to make loud, disruptive noises while you’re driving.

Purifiers, in general, shouldn’t make more than a dull noise. The more quiet it is, the better. If for some reason yours is extra noisy, this could mean the fan is overheating, and this can be dangerous. In that case, it’s advisable to remove it and call the company and ask for a refund or replacement.

How Will It Fit in My Car?

While some car air purifiers plug into your vehicle’s power outlet, others will require placement in other areas. This could be behind a headrest or in your cup holder.

There are also ones that come in bags; these can easily be placed underneath your seat or in another discreet location. Keep in mind the size and design of your car interior and how a certain product will fit.

Every product is different, so the installation will vary, depending on which one you buy. If you choose to go with an ionizer, don’t worry about facing difficulties when it’s time to install it – it’s super easy. All you do with these is connect them to your power outlet and they will get right to work.

Other air purifiers may require a little more work. If they need to be fastened to the back of your headrest, be sure to look out for products that come with everything you need for installation. This will make your life a million times easier than trying to jury-rig it into place.

Also try to look for one that’s lightweight, heavy car air purifiers can be annoying to deal with for one too many reasons.

Does It Require a Lot of Maintenance?

Just like any other device, car air purifiers will require at least some amount of maintenance and upkeep. In order to keep it running effectively, it is important to clean the filter out regularly.

When making a purchase, keep in mind how easy or difficult it is to maintain the purifier. If it’s easy, you should be able to clean it regularly. If it seems more difficult or downright impossible, you may just have to keep purchasing replacement filters!

A product which has some sort of signal or notification, one that alerts you when it’s ready to be changed or replaced, is a major plus.

If your purifier has a HEPA filter — as many purifiers do — there is a proper way to clean the filter so that you don’t have to keep replacing it unnecessarily.

Check out this YouTube video below to learn how to properly clean your air purifier and filter. Cleaning it out once a month will go a long way in helping it last a long time.


Try to keep it budget friendly whenever possible, because – and I’m sure you agree with me on this – we all already spend enough on our cars already!

California Home Goods Bamboo Charcoal Air Purifying Bag

If the thought of an ionizer and its production of ozone makes you uncomfortable, this more natural option may be a better choice for you. These purifying bags by California Home Goods are filled with activated charcoal.

We like these purifying bags because they’re reusable and will work just about anywhere. They can be used for up to two years and also come with a product lifetime guarantee, so if you aren’t satisfied, you’ll get your money back from the manufacturer.

These are especially useful if you’re a pet owner and you drive regularly with them. The bamboo charcoal will work as an eliminator against the worst of odors, so if your best paw friend has an accident or his smelly fur permeates the enclosed atmosphere, you won’t need to worry.

The bags are made from non-toxic material, so they are also safe for families with small children to use.

The company recommends laying these bags in the sun once a month to clear out the cavities of the charcoal. If you do this, they should last you quite a long time, and – if everything goes well – they can be reused for up to two years.

Features and Specifications

  • Product lifetime guarantee.
  • Non-toxic and eco-friendly.
  • Four bags of charcoal.
  • Specially formulated, carbon-activated bamboo charcoal.
  • Two years of use per bag.

What We Like

  • A natural approach to air purification.

For anybody trying to live a more naturalistic lifestyle, these bags are a great way to purify and clean the air in your car without feeling guilty. They are completely non-toxic, to the extent that the company even recommends dumping the bags in your garden after two years of use.

The contents are reusable, just leave them out in the sun to dry once a month, and they will work virtually anywhere. They can easily fit in small spaces such as gym bags and discreet spots in your vehicle, which is great for convenience. An excellent option if you’re looking for a mini car air purifier!

Philips GoPure Compact Air Purifier

PHILIPS GPC20GPX1 GoPure Compact 200 Car Air Purifier, 1 Pack

If you’re looking for a product that works quickly and efficiently, this compact device from Philips is worth a look. It will remove up to 99% of toxins in your vehicle in a matter of just 15 minutes – quite impressive if you ask me!

The GoPure purifier has a unique three-layer filtration system, featuring both HESA and HEPA filters. Its pre-filter catches the big stuff — hair for example — and then the HEPA filter catches dust, pollen, and other bacteria.

After the air passes through the HEPA filter, the HESA filter steps in and reduces unpleasant odors, due to pollutants such as an exhaust and cigarette smoke.

It also comes with an automatic switch-on when you enter your vehicle and start it up, which saves you the effort of having to reach around to turn it on every time you’d like to use it.

Along with an LED light to indicate when it’s time to change the filter, it also comes equipped with air quality sensors — blue for excellent, yellow for fair, and red for poor quality.

It is recommended to change the filter every 8-12 months, depending on how frequently (or infrequently) you drive.

Features and Specifications

  • Healthy air indicator.
  • Sensor to change the filter.
  • 3-step filtration system.
  • Automatic switch-on.
  • Comes with 2 speed settings.
  • Comes with mounting accessories.
  • 12v Power cable length: 4 meters.

What We Like

  • HEPA and HESA filters.
  • Indicators for air quality and filtering change.
  • Turns on automatically when you start your vehicle.
  • 3-step filtration system ensures healthy air quality.

What We Don’t Like

  • Noise level might not be everyone’s definition of silent.


If you’re looking for something that will ensure good air quality in your vehicle, this is a great option for you.

This is especially a good option to consider if you have pets that ride along with you, or if you (or other passengers) tend to smoke in your vehicle.

The 3-step filtration system is also pretty hard to beat, as it gets down to the nitty-gritty and eliminates the odors and other pollutants from your vehicle.

This is a great choice to consider since not only can you use it in your car, but it can also be used as a home air purifier (or at the office) as well. In order to do that, however, you will need an adapter that it can plug into. If you own an RV, this will work well in there too. Keep in mind that these should not be plugged into an adapter with more than 12v of power.

This particular air purifier is great for car smokers because it dispels smoke quickly to eliminate the smell of cigarettes from your vehicle.

This means riding alongside you won’t be as annoying because of the smoke – which you’re better off quitting, by the way! Tobacco is bad for your health, but that’s another story for another day.

The only downsides to this purifier we could think of are that you will have to replace it every 12 months or so when it stops working, and the fact that it’s not suitable for 24v power outlets.
