Most car air purifiers are very easy to use and require little to no maintenance. Depending on your preference you can opt for a unit that uses HEPA filtration or an ionizing unit. The products based on filtration seem to work faster and get better results, although they do represent a bigger initial investment and require some maintenance. The ionizers on the market are smaller and less expensive and they work by emitting negative ions which bind to harmful particles and make them stick to surfaces instead of floating in the air. The downside of this system is that you might have to clean your car surfaces more often, as they will get covered in dust.

Criteria Used in Evaluation

Of The Best Car Air Purifiers



Different car air purifiers tackle the issue of harmful particles in different ways. The two most common technologies used are the HEPA filtration system and the ion emitting system. When deciding which product will suit your needs best, it’s good to know how the product will go about doing its job. Ionizers tend to be simpler to use, less expensive and require no maintenance. They work wonders for unpleasant odours, such as cigarette smell, animal smells and leftover food odours, but seem to be less effective when it comes to getting rid of allergens. On the other hand products that use the filtration systems represent more of an initial investment, but work better for dust mites and other particles that cause allergic reactions. They also tend to get results quicker. In addition to ionizers and HEPA systems, some products also use ozone generation to tackle bad smells. Instead or in addition to emitting negative ions, some units emit low levels of ozone, which bind to odour producing chemicals to neutralise them.


The price range of car air purifiers is very broad, which makes it difficult to know which products are overpriced and which ones provide you with cleaner air at an affordable price. This is why we have included products from both ends of the spectrum that get the job done. The HEPA systems are generally on the more costly side, as they promise results in a matter of hours and pride themselves in tackling allergens much better than ionizers. In addition to being more pricey, they also need their filters replaced every now and then, which adds to the cost. Most ionizers on the market are available for a substantially lower price, but still get the job done. Regardless of your budget, we are sure this list includes a product that will meet your needs without putting too much strain on your bank account.

Ease of Use

Dealing with technology that isn’t intuitive to use can be very frustrating, so it is very important the product you are purchasing is easy to use. Most car air purifiers are pretty straightforward, requiring only the 12V cigarette lighter in your car in order to work. Simply plug it in, and it starts doing its job. MOst work immediately after being plugged in, while others have an On/Off button. The fact that the product is working is usually indicated by a small LED light and a quiet humming sound. Some of the more technically advanced and bulkier car air purifiers take a bit more time for installation, as they need to be mounted on the dashboard or behind the driver’s seat. A lot of car air purifiers come with an adapter, which enables you to use them outside the car as well.


While some car air purifiers require nothing more than to simply plug them and forget about them, others require a bit of maintenance every now and then. The units utilizing the HEPA filtration system will need to have their filters changed every now and then to keep them working optimally. Most of them comes equipped with a filter indicator, which means a light will turn on to let you know it’s time to get a new filter. Ionizers don’t require any maintenance, although since they cause the harmful particles to stick to the surface, your car might need cleaning a bit more often than you’re probably used to. The units that require filters to be changed generally have a longer lifespan compared to the ionizers.

Extra Features

It’s always nice to have the feeling you’re getting a bonus when purchasing a product. Some car air purifiers come with extra features such as additional USB ports, so you can charge your device while using them.This is especially handy for the units that work by plugging them into the cigarette lighter in your car, as this way the USB ports are in a very handy position. The HEPA filtration units will often have an indicator for air quality in your car, which is definitely a nifty feature to have.This enables you to adjust your usage to the air quality and it gives you an idea of which factors influence the air quality in your car the most.


Some car air purifiers are portable, meaning you can take them out of your car and use elsewhere. The portable units work well in closets, small rooms or even in shoes to get rid of any unpleasant smells. They tend to work best in small rooms, as their compact size means they probably won’t be strong enough to effectively clean the air in bigger rooms. The portable units come with adapters, which enable you to plug them into your regular socket.


Even though performance is more important than style in this type of product, it doesn’t hurt to have an attractive looking device in your car. After all you are more likely to use a product if you find it visually appealing. For the minimalistic customer, the smaller, inconspicuous units will have an edge over the bulkier, flashy looking ones. Ionizers tend to be smaller, and once plugged in they are hardly noticeable. If you’re looking for a fashion accessory for your car, some products, especially the HEPA filtration systems pride themselves for their futuristic, stylish look. The blue LED light that shows the product is working adds a nice calming vibe to your car.


Products coming with a warranty from the manufacturer will always have an edge over the ones that don’t. Being assured that your product will get replaced, if it does not meet your standards and that you will receive your money back if you’re not satisfied, lends a sense of confidence of the manufacturer in its product. It lowers the risk involved in purchasing a product and allows the customer to change his mind if it turns out the product doesn’t meet their needs. This is an important issue that we have taking into account while compiling the top 10 list.

Product Production

Whether or not the product does its job well is irrelevant if it breaks down within the first week of using it. This is why the quality of materials and how well the product is made is very important, especially when it comes to products that involve technology. In some cases, paying a bit more guarantees a product of a higher quality, while other products are well made despite their affordable price. To prevent you from falling for expensive and ineffective, or cheap and poorly made products, the lifespan of the product plays an important role in our ranking system.


Frequently Asked Questions

About Car Air Purifiers


Q: What is the difference between HEPA filtration systems and ion emitting car air purifiers?

HEPA devices use a filtration system that traps harmful particles, dust mites, mold spores and chemicals causing bad odours inside the filter located in the device. They use fans to guide the air though the filter, leaving the air free of pollutants. Ionizers don’t use a filter or a fan. They work by emitting a large number of negative ions or anions into the air. These ions then bind to positively charged harmful particles in the air like pollen or dust which causes them to stick to surfaces instead of floating in the air.

Q: How do ozone generators work?

Instead of filtering air, they generate ozone in low, safe levels. Ozone interacts with chemicals responsible for bad odours in such a way that it makes them odourless. This works quite well for a number of different odours, including long lasting, lingering smells, like tobacco, pet smells and food odours. Since ozone generation works well for bad smells, but doesn’t get rid of harmful particles in an effective way, most units that generate ozone also use an additional technology (like filters or ions) to tackle pollutant particles.

Q: I suffer from occasional asthma issues. Are car air purifiers suitable for me? Which product would work best in my situation?

Yes, car air purifiers are suitable for people suffering from asthma or allergies. Although most car air purifiers promise to remove allergen particles from the car cabin, the HEPA filtration system seems to work best when it comes to reducing allergies and asthma symptoms. They tend to work fast and remove 99% of the offending particles within the first hour.

Q: Do they give off a perfumed smell?

No. Most units simply remove particles that cause bad odours without using any chemicals or perfumes. Their action leaves the car smell neutral, without using heavy perfume to cover up bad smells. Ozone generators sometimes give off a fait smell, but it is not a heavily perfumed smell.

Q: I smoke in my car on a daily basis. I have been using air fresheners, but they don’t help with the problem. Will a purifier help with the smell?

Most car air purifiers get rid of harmful particles as well as unpleasant odours. Tobacco smell is one of the most common smells customers are looking to get rid of. Both the ionizers and the HEPA filtration units do a great job at getting rid of tobacco smell.

Q: Do they all have fans?

No. Products that utilize ionizing technology don’t use fans, as their function is merely to emit a high concentration of negative ions, as opposed to filtering air. This contributes to them being more quiet than the products which use fans to work.

Q: Are there any health risks that come with ozone generators?

The ozone levels generated by car air purifiers that utilize this technology are very low and are considered to be safe. If you are worried about exposure to ozone, perhaps opt for a product that does not emit ozone, but tackles bad smells and pollutants in a different way, such as ionization or HEPA filtration.

Q: How do I know the product is working?

Some car air purifiers are very quiet so it’s sometimes hard to know if they’re working or not. Most come equipped with a LED light, which turns on when the product is plugged in.

Q: How often do I need to replace the filters in HEPA systems?

It depends greatly on how much time you spend driving, how often you use it and which setting you use it on. It also depends on the product itself. Both the Phillips GoPure Compact 200 and the Homdox generally need a new filter every 6 months, if you are using it approximately five hours a day.

Q: Can the LED light be turned off?

As the light is an indicator that the unit is working, it cannot be turned off. If the light is too bright, some customers recommend you turn the product in such a way that the light is facing downward.

Q: What is inside the Bmbu Bamboo Charcoal Deodorizer?

The bag contains pure bamboo charcoal, with no additives or filters.

Q: Are car air purifiers noisy?

While none of the devices are completely silent, they are generally not noisy. They may produce a low, humming sound, that you hardly notice. In most cases, you can’t hear them at all once the car is running or the radio is on.

Q: Will the car air purifiers drain the car battery if they are left plugged in?

They will not, as they are only working and using up energy when the car is running.

Q: What’s the difference between car air fresheners and car air purifiers?

Air fresheners usually work by giving off perfume into the car cabin. The pleasant smell of the perfume merely covers up any unpleasant odour, while it does nothing for pollutants and other harmful particles. Car air purifiers actually remove particles like pollutants, allergens and dust mites. They also get rid of bad smells using technology instead of simply covering the smell up.
