Best long-lasting car air freshener

Keep your car smelling clean for months on end

For commuters and those who spend a lot of time in the car, one big consideration is the scent of that car. One of the easiest ways to deal with how a car smells is through the use of air fresheners. While most are affordable and work well immediately upon opening, car air fresheners tend not to have much longevity and stop making a difference in the scent within a couple weeks. Finding a long-lasting air freshener can be a harder decision than most would expect.

Air freshener features to consider before buying

Removing odors vs. masking odors

One of the biggest distinctions between air fresheners is whether they’re actually eliminating the odors from the air, or just masking the scent of them with a different scent. Some air fresheners can absorb odors, so even when they no longer work, the car won’t be plagued with unpleasant smells. 


The largest issue is how long a car air freshener will last before no longer being effective and needing to be replaced. The cheapest car air fresheners usually last somewhere between a few days and a few weeks. However, some higher-quality options available can last for up to a year while still being effective. These air fresheners likely cost more than ones with a shorter lifespan. 

Scented vs. unscented

When choosing an air freshener for the car, decide whether to buy a scented one or an unscented one. Many air fresheners simply mask or remove odors without replacement, while others offer dozens of different unique smells. For some users, having the right scent can make a big difference to their enjoyment of the product while for others, it’s just about removing bad smells. 

Car placement

Another major component is actually where the air freshener is placed in the car. While traditional air fresheners fit around the rearview mirror, others have different places where they’re designed to fit. Some fit perfectly in the cupholder, while others hang on the back of the headrest. Specific types of air fresheners clip on the air vents and rely on the movement of air to diffuse the scent.
