The best car air purifiers in 2022

The best car air purifiers for 2022, we’ve put through a thorough review to pick out the 6 best car air purifiers for you.

To find the best car air purifiers, you’ll need to examine a list of criteria to determine what is most important. We recommend the best car air purifiers with true HEPA and activated carbon filtration for ultrafine and odor-resistance. Look for built-in ionizers to emit a minimum of 4.8 million negative ions per cm³ for good coverage. Bonus points go to a variety of mounting options (vertically, horizontally, on the dashboard, behind the rear seat headrest) for optimal intake and airflow distribution, along with a cigarette lighter, adapter, and USB connectivity for an indefinite charge. These are also some of the features found in our top-rated air purifiers.

While the air system already in place in your car might filter out the majority of particulates, you may want to add an additional air purifier for some added peace of mind—especially if you drive for a rideshare company or have a lot of people in and out of your vehicle. Similar to home air purifiers, car air purifiers offer convenient protection against harmful pollutants caused by sitting in traffic, living in congested cities, or even your passengers.

To help you find the right purifier, we dug through thousands of reviews for a variety of options available online. Based on our research, these are some of the best car air purifiers you can get right now.

Car Air Purifier Buyers Guide

Before making a purchase, learn more about the different types of air purifiers and how they can improve your vehicle’s air quality.

Types Of Air Purifiers

In-cabin air filters are one of the best ways to prevent irritants and pollutants from building up in your car. Unlike most filters, these are built directly into a vehicle to pick up dirty air as it passes through the HVAC system. Although reliable, the downside to these filters is that they must be replaced every few months.

Ionic air purifiers target odors and other pollutants at a molecular level. These purifiers emit positively or negatively charged ions that trap and break down unwanted particles that spoil the air. While these are ideal for eliminating foul smells, they take longer than other types of filters to show results.

Charcoal air filters are environmentally friendly, as they’re made with naturally sourced materials. Charcoal filters absorb irritants and odor-causing chemicals directly. Once full, these bags can be placed in direct sunlight to be refreshed and used again. The typical charcoal filter lasts about two years and leaves behind no fragrance.

Car Air Purifier Key Features

Size and portability: Car air purifiers are compactly designed to fit in your vehicle without taking up more space than they need to. Most purifiers can fit in cup holders or on dashboards, while others can be hung from the rearview mirror. Some purifiers are made to fit around the back of headrests.

Power source: Most car air purifiers are battery-powered to conserve energy. Some are even rechargeable, using the outlets in your car as a charging source. Others can install into the cigarette lighter of your vehicle to run.

HEPA-rated filter: High-efficiency particulate air (HEPA) filters are certified to grab more pollutants from the air than non-certified ones. Make sure your device is using one of these filters to have the most effective air cleaner possible.

Our Review Standards

The five car air purifiers that best met these standards were ordered by our team for testing. A team member tested each product on a car, taking note of how well each air purifier fit in our testing vehicle, how long it took to achieve noticeably cleaner air, the amount of noise it produced, and its portability. Each air purifier was given a rating out of 5 stars based on this criteria.

The Most Important Features to Consider


Our preference is for car air purifiers to carry triple-level filtration to capture 99.97% of allergens and a favorable square footage rating that exceeds the total vehicle space for best results. A 3-stage filtration system should incorporate at least a HEPA filter and activated charcoal filter with an optional ionizer to work extra in binding and ground contaminants for easy removal.


Go for car air purifiers that are cigarette lighter or adapter compatible, working with USBs. This will enable it to run indefinitely in your vehicle without worrying about recharging times. Additionally, focus on digital extras such as real-time air quality monitoring using color-coded LEDs or Bluetooth/WiFi app compatibility. This gives users a true sense of air quality on the fly.

Mounting Options

We love car air purifiers that can be mounted horizontally, vertically, on dashboards, and behind seat headrests. Just as important is its airflow setup, with a nod to the cylindrical 360-degree air intake for more even distribution of intake and airflow to reach the entire vehicle interior.

Which is the best car air purifier?

In our opinion, the best car air purifier offers triple-level filtration to capture 99.97% of allergens, along with several mounting options that make it equally look good on a dashboard or back seat top. The ionizer-based car air purifier should deliver a minimum of 4.8 million negative ions per cm³. Don’t forget a cigarette lighter or adapter compatible units that can be charged and run indefinitely in a vehicle instead of waiting for a dreaded recharge.

Are air purifiers really worth it?

Yes, we feel air purifiers are definitely worth it. Ion technology and ionizers do an exceptional job of neutralizing and grounding airborne pollutants, making the air much easier to breathe.

Are air purifiers a waste of money?

The only air purifiers we feel are a waste of money are ones that do not include strong ionizer output and 3-stage filtration. Thin mesh designs are a no-no. Not all air purifiers are created equal.

Do you need a car air purifier?

Although in-car air systems do a decent job of preventing airborne contaminants from reaching your interior, a car air purifier is a must when frequently opening or closing windows. Large spiraling urban areas with high traffic congestion and exhaust gases can cut into overall health over the long run, so a functional car air purifier does not hurt in keeping the air you breathe fresh and contaminant-free.

How long should I leave my air purifier running?

When you first install or place one in your vehicle, you should run it all day and leave it running. There are no downsides to having it clean your car’s air, especially if it has a rechargeable battery. Purifiers that install directly into your car will automatically activate when your car is turned on. If you are using charcoal bags, simply install and leave them in your vehicle.

How long do car air purifiers last?

This depends on the type of purifier and the rate at which it cleans your air. A good rule of thumb is to replace the removable HEPA filter in your air purifier every six to twelve months, depending on the air quality of your vehicle and environmental factors. Carbon filters and charcoal bags require a quicker turnover rate of every three to six months.

Can HEPA filters be reused?

HEPA filters marked as “permanent” can be cleaned and reused. They can be cleaned using warm water and a vacuum cleaner to remove built-up dirt and debris. HEPA filters that aren’t marked “permanent” should not be used more than once.

Do air purifiers need water?

Unlike humidifiers, air purifiers do not add any water to the air. Humidifiers do not actually clean the air, either, as they only add moisture.

Is an air purifier effective in the car?

Several cars use HEPA filters that are effective only against PM2. 5 and the SPM inside the car cabin, but they won’t be effective against airborne communicable viruses. So if you want to protect your family while traveling, you should use an AMT-based car cabin air purifier.

Do air purifiers prevent Covid?

When used correctly, air cleaners and HVAC filters can help reduce airborne contaminants in a building or small space, including viruses. Air cleaning or filtration is not enough to protect people from COVID-19.

Our car air filters HEPA?

And that’s where your car’s cabin filtration system is similar to the mask. Some car filtering systems consist of a HEPA filter designed to purify or filter the air coming into your vehicle’s cabin. HEPA Filters in automobiles are a type of pleated air filter.

Do air purifiers generate ozone?

There’s no ozone emission from air purifiers that use only high-efficiency particulate filters (HEPA filters) to cleanse the air. Ionizing air purifiers, because of their electric charge, do create ozone. Consumer Reports has warned that they may give off potentially harmful ozone levels.

Are air purifiers a waste of money?

So, it’s only typical that you may be wondering are air purifiers a waste of money. According to the EPA, they’re worth it as they’re an excellent way to enhance your Kearney residence’s indoor air quality.

Do electric cars have air filters?

Electric cars have motors, not engines, and don’t need to shift gears, so they don’t need engine oil, spark plugs, air filters, coolant, or transmission fluid.

Does the venue have an air purifier?

The Venue was one of the first SUVs and cars, in general, to have an air purifier fitted. We recommend the Venue, and the air purifier has a HEPA filter that filters out dust particles. It is also one of the most affordable cars to have an air purifier standard in some of its top-end trims.
