For those interested in learning more, we’ve provided a detailed review of each of the best car air fresheners in the sections below:
The Air Spencer is a Japanese car air freshener that’s popular in the United States for its pleasant scent and longevity. It’s one of the longest-lasting air fresheners that we tested, and the design doesn’t require you to dangle anything from your mirror or take up space in your cup holder.
We’d recommend the Air Spencer CS-X3 car air freshener if you want a pleasant scent that covers your vehicle and stays consistently powerful. It’s also a great option if you don’t want anything to hang from your mirror or cover up your cup holder. The Air Spencer can easily be placed just about anywhere in your vehicle. We also like the adjustment mechanism that makes it easy to set your desired potency.
You can see how the Air Spencer CS-X3 performed in each of our testing categories below:
A full 83 percent of customer reviews give the product 4.0 stars or more. Most customers agree with our assessment, finding that the CS-X3 lasts a long time, looks sleek, and produces a pleasant smell.
Some customers claimed that the Air Spencer didn’t last long enough. It may be that these users bought a scent with shorter longevity than squash or possibly that the product runs out quicker when fully opened. Another issue is that the Air Spencer doesn’t do well in the heat. One person said the device melted and warped in 100-degree weather.
The Air Spencer has two components: a plastic case and a changeable gel insert that releases scent. There are several different scents available, but we chose squash, which had a pleasant smell that was actually reminiscent of bubble gum.
A sliding lever changes the gel insert’s exposure and thus the strength of the smell. You can put the CS-X3 anywhere in your car. The bottom has a sticky adhesive that makes it easy to attach to your dashboard, but you can put the small, slender device anywhere in your vehicle.
When the scent finally dies out, you can purchase refill packs in squash, lime, citrus, and crystal flavors. These cost around $8 per refill.
Of the best car air fresheners, we had the top experience overall with this one. Our testers enjoyed the scent but were most impressed by the style of the device as well as its longevity. The smell also permeated the whole car interior .
The Moso Natural Air Purifying Bags contain activated bamboo charcoal and are designed to absorb foul scents to purify the air. Unlike most of the other best car air fresheners, the Moso Natural bag is actually fragrance-free.
Moso Natural works in a space of around 90.0 square feet, which is perfect for absorbing odors from your car cabin or your trunk. Bamboo charcoal is very porous and has a lot of surface area. Odor particles are trapped in the charcoal as air flows through the bag.
The Moso Natural air purifying bags can effectively deodorize a space for about two years, after which the charcoal can be used as a natural fertilizer in your garden. You can see how the Moso Natural performed in each of our testing categories below:
Roughly 80 percent of reviewers give the product 4.0 or more stars. Most customers were impressed with the bag’s odor-eliminating capabilities, with several noting the effectiveness of these bags on cigarette smoke and pet odors.
“We have a daughter and son in law living in our basement. While they don’t smoke in the house, the smell of smoke on their clothes is very strong. I put two Moso bags in their basement apartment and the cigarette smoke odor is nonexistent.”
There are a few reviewers who claim to have not noticed any difference when using these bags, but such reports are in the minority.
We used the Moso Natural air purifying bags in our vehicle’s main space as well as in a trunk packed with smelly gym clothes. After a couple of hours in the trunk, the bad smell was almost entirely gone. While the odor elimination is not as immediate as with a spray, it remains effective.
The Moso Natural air purifying bags are a good choice for those who don’t like chemical air fresheners and would prefer to avoid them. We would recommend the Moso Natural air purifying bags to those who want one of the best car air fresheners but have an allergy or sensitivity to stronger fragrances.
The Chemical Guys New Car Smell attempts to imitate the smell of a new vehicle. The scent isn’t overwhelming but the car air freshener excels at covering up disagreeable smells.
While your car won’t come out smelling brand new, Chemical Guys New Car Smell may be just about the closest you’ll get. If you’re cleaning your vehicle or trying to eliminate a very pungent odor, this stands as one of the best car air fresheners on the market.
A used car with a funky scent or an unfortunate-smelling vehicle could easily be fixed with a few sprays of the Chemical Guys New Car Smell. You can see how the Chemical Guys New Car Smell performed in each of our testing categories below:
Many customers note how well the product masks bad smells, especially cigarette odors. A few reviewers mentioned that they were impressed with how well Chemical Guys New Car Smell worked after being diluted.
One reviewer mentioned that the car air freshener damaged the plastic cover on his instrument display. Others find the scent of Chemical Guys New Car Smell off-putting. The product receives 4.0 stars or higher from 77 percent of reviewers on Amazon.
While it doesn’t perfectly match that new car scent, Chemical Guys New Car Smell comes close and provides an extremely pleasant smell. We used the product undiluted and found it to effectively mask bad odors.
This air freshener from Chemical Guys has odor-eliminating enzymes as well as a perfume to keep your vehicle smelling like new. According to the directions, a single spray is enough to scent your car and our in-person testing confirmed this.
The product is concentrated and can be used either as-is or when diluted with up to two gallons of distilled water. You may run out quickly if you spray your vehicle every day, but that’s almost never necessary.
The Ozium Smoke & Odors Eliminator absorbs and effectively eliminates unpleasant smells. It’s particularly effective at removing cigarette smoke and other strong fragrances from your vehicle.
Ozium is a good pick for smokers and those trying to eliminate cigarette smoke or other strong smells. It is one of the least cost-effective car air fresheners we tested, though, as it doesn’t last long compared to some other picks. You can see how the Ozium Smoke & Odors Eliminator performed in each of our testing categories below:
About 78 percent of reviewers give the product 4.0 or more stars. Many of the positive reviews come from cigarette smokers or those attempting to eliminate the smell from their cars and homes. Satisfied reviewers are extremely impressed with the effectiveness of Ozium.
“I bought a used car that smelled so bad of cigarette smoke, like the person before me puffed all day and night … I’ve now had [Ozium] in my car for almost two months and I no longer smell cigarette smoke at all.”
As with most car air fresheners, some strongly dislike the smell. A few people complain that the scent is very strong, at least when the can is initially opened.
We found Ozium to work as advertised and it was especially good at eliminating bad smells. Even compared to the best car air fresheners, the Ozium Smoke & Odors Eliminator is extremely effective and provides a powerful scent.
To use the Ozium Smoke & Odors Eliminator, simply place it anywhere in your vehicle. The Ozium gel will absorb bad odors over time while producing a pleasant smell of its own.
Febreze Unstopables stand as a popular choice among the best car air fresheners. They come in a number of scents and easily clip to your car’s air vent. This makes them a low-profile option that begins working almost immediately.
Febreze Unstopables can clip straight onto your car’s air vent and start slowly dispersing scents as the air comes out. These car air fresheners help to eliminate foul odors and replace them with one of many pleasant scents. You can see how the Febreze Unstopables performed in each of our testing categories below:
Most reviewers comment that the car air fresheners work well, and many are satisfied with how long they last. Very few found that the Febreze pods offered less than a month of use. Those who leave negative reviews do so primarily because they don’t like the available scents. About 89 percent of reviewers gave the product 4.0 stars or higher.
We liked the Febreze Unstopables air vent clip and found that it lasts a relatively long time. The scent is not too strong and does an exceptional job at masking bad odors. This was one of the faster-working air fresheners, covering bad smells nearly immediately upon use. The device sits out of the way and won’t obstruct your vision while driving.
Of the car air fresheners we tested, the Febreze product was the most conveniently located as it doesn’t take up space in the cup holder or on the floorboard.
Febreze Unstopables Car Air Vent Clips provide a strong option for those who don’t want to dangle anything from their windshield or lose space in their cup holders. They’re also a good choice if you need to quickly eliminate bad odors in your vehicle.
Every person holds different preferences on what the best car air fresheners should offer. However, it’s worth knowing the differences between the different types of car air fresheners.
Car air fresheners come in a range of types that release scent and attach to your car in various ways. But which type of air freshener is best for your car? It’s smart to learn about each type to discover which one will work best for you and your vehicle.
This is the most affordable version of an air freshener, but you’ll probably get what you pay for as cardboard models only last for a short time. They most commonly come as little trees that are hung from your rearview mirror.
A plug-in air freshener usually clips onto the air vents of your car or has a cigarette lighter end with a liquid container attached. It works similarly to a home air freshener that plugs into a wall outlet. Once it’s plugged into the lighter port or air vent while your car is running, its scent gets released.
This type of air freshener comes in a plastic or metal canister with a gel-like substance in it. The lid of the canister has holes, and you can usually twist the lid to decide how many holes you want open. The more holes that are open, the more scent the gel will release. Can-shaped car air fresheners are generally placed into a cup holder.
Vent clip car air fresheners are pretty similar to cigarette lighter plug-ins due to their container of liquid. These models differ because you clip them onto your air vents, which release the scent as air flows out.
A spray air freshener isn’t like the others that release scent over some time. This version comes in a can that you spray whenever there’s an odor you want to mask. With this type, you have the option of directly spraying the area that smells bad.
Here are some factors worth considering as you choose the top car air freshener for your personal needs.
Scent is arguably the most important factor when choosing a car air freshener because it will determine how your car smells for the foreseeable future. For those focused on aromatherapy and in search of essential oils, there’s even more to consider before choosing a scent.
A can may take up one of your cup holders – a big sacrifice if you’ve got a sedan with only two. A plug-in may not be that large, but it takes up a cigarette lighter that could be used to charge electronics. If you want a car air freshener that’s relatively unobtrusive, a rearview mirror or car vent clip is your best bet.
You’ll want to pick a brand that offers a variety of scents so that you can find one you like. Even better is a variety pack that allows you to try them all in a row. This also makes it easy for drivers to switch between scents if they get sick of one after a while.
Odor Neutralizer Vs. Air Freshener
High-quality air fresheners will completely eliminate unpleasant scents but tend to cost more. You’ll have to decide if you’re willing to settle for a car perfume that simply masks bad odors with its own scent for a reduced price.
The duration of the scent will determine how often you have to buy new car air fresheners. More expensive ones, like the vent clips and clip-ons, will generally last longer, while cheap air fresheners will typically stop being effective after around 30 days.
Having an effective car air freshener is a crucial part of any car cleaning arsenal . For an investment you’ll likely be spending plenty of time in, you’ll want a way to combat unpleasant odors.
Our top picks are the Air Spencer CS-X3 Air Freshener as a great set-it-and-forget-it option, although more meticulous car owners who clean their cars regularly may prefer the best spray we tested: the Chemical Guys New Car Smell.
Here are our picks for the best car air fresheners on the market in 2024:
Below are some common frequently asked questions about car air fresheners:
It depends on the state and the size of the air freshener. For example, Virginia law says that you can’t hang anything from the rearview mirror that could obstruct the driver’s view. It’s best to know your state’s specific laws before purchasing a hanging air freshener.
In our testing, we found that the best car air freshener with a long life span was the Air Spencer CS-X3, which lasted for several months in our test vehicle.
There isn’t one scent that works for every person. That’s why most car air fresheners come in a variety of scents to let drivers choose one that best suits their fragrance preferences. Most brands will at least have a clean laundry scent and a fruity scent.
The best car air fresheners are a good way to start keeping your vehicle smelling fresh but car accessories are another route. You can also vacuum your car to remove debris, clean the carpets to eliminate smelly stains, and take out all trash when you leave the car.
It depends on the type of car air freshener you purchased. The instructions usually give a fragrance life, but the guidelines aren’t always accurate due to factors such as climate that can affect longevity. The best rule of thumb is to change it once you no longer smell the scent.
The new car fragrance comes from various chemicals released by components found in most new vehicles. From rubber to your car’s upholstery, new automotive parts emit countless gases.
To test each of the best car air fresheners, we installed them in the front seats of cars and then in a trunk filled with sweaty gym clothes. We noted the strength of the scent from the front and rear seats, along with how well each car air freshener masked bad odors.
Each candidate for the best air fresheners was left in a vehicle until it stopped performing. In some cases, air fresheners lasted for several months. We rated each of the best car air fresheners using three main criteria: longevity, odor-masking abilities, and overall value.
Longevity is important when determining the best car air fresheners. After all, even the best-smelling products aren’t worth using if they only last a day. Some car air fresheners will last for several months straight. Air fresheners that continued to perfume the vehicle the longest score best in this category.
A common use for car air fresheners is to cover up bad smells in your car, from pet odors and cigarette scents to dirty clothes and food spills. We took note of how well each of the best car air fresheners was able to mask the smell of stinky clothes in the trunk of our test vehicle.
Air fresheners most able to diminish or remove bad odors score best in this category.
We determined the value of each air freshener by comparing their cost with how long they generally last.
Every air freshener we test is given a score between 1.0 and 5.0 stars in each category. Here’s what those star ratings mean in concrete terms:
Each year, we test over 350 auto products on vehicles and in our testing lab. Our team of product testers thoroughly researches top products, unboxes and puts our hands on each component, and tests the items on real vehicles before making recommendations to readers.
