Last Updated on April 12, 2023

Air fresheners can make your car smell fresh and clean, but you may wonder if you can spray air fresheners directly on the car cabin air filter. Even though spraying air freshener on your car’s filter may help remove some odors, it may not be the most effective solution.

Because some air fresheners can clog the filter’s pores, making it less effective at trapping pollutant particles. Also, the chemicals in the air freshener can break down the filter material over time, causing it to degrade more quickly. In this case, you shouldn’t spray some air fresheners directly onto cabin air filters.

Fortunately, some air fresheners have formulas that won’t damage your filter. The following information will help you understand how to safely use air fresheners on car cabin air filters.

Can You Spray Air Freshener Directly on Car Cabin Air Filter?

If you’re looking for a quick and easy way to freshen up your car, you might be tempted to reach for the air freshener and give the cabin a good spritz. The cabin air filter on a vehicle is designed to trap pollutants and keep them out of the passenger compartment, and spraying a foreign substance on it can compromise its effectiveness.

But before you do that, it’s essential to check the ingredients in your air freshener. If it’s oil-based, spraying it directly onto your cabin air filter could cause problems. The oil can build up on the filter, reducing its ability to trap pollutants and debris. This can eventually lead to a musty-smelling cabin and reduced airflow.

Also, many air fresheners contain chemicals that can be harmful if inhaled while mixed with car exhaust fumes. So you should avoid spraying oil-based air fresheners straight into the car cabin air intake.

But some odor removal air fresheners are specifically designed not to clog filters or damage cabin air quality so that they can be sprayed directly on the filter.

How to Use Car Air Freshener With Car Cabin Air Filter

If you want your car to have a pleasant scent, it’s important to use air fresheners correctly. There is a common misconception that air fresheners should be sprayed directly on the cabin air filter of a vehicle. Unfortunately, this can decrease the effectiveness of the air freshener.

In contrast, if you use the correct air freshener, you will experience a delightful new car smell for weeks to come. Here’s what you need to do:

Step 01. Collect Required Materials

To use an air freshener with your car cabin air filter, you’ll need the following materials:

  • Car air freshener of your choice
  • Pin or paper clip
  • New cabin air filter (if required)

Step 02. Locate & Detach the Cabin Air Filter

When using a car air freshener with a car cabin air filter, you need first to locate the cabin air filter. The cabin air filter is usually located in the glove box on the car’s passenger side. To find it, open the glove box and look for a small door on the side. Once you’ve found the door, detach the hinges with a screwdriver.

Behind the door, you should see the cabin air filter. Next, detach the car cabin air filter from its housing. Once you’ve removed the filter, you can put the freshener on the housing.

Step 03. Attach the Car Air Freshener

There are a few different ways to attach your car’s air freshener to the cabin air filter. The most common way is to use a pin or paper clip. Create a hole in the top of the air freshener and thread the pin through it. Then insert the pin into one of the holes in the cabin air filter.

Another option is to attach multiple air fresheners to different sides of the filter, allowing you to customize the scent in your car. Whatever method you choose, ensure that the air freshener is securely attached, so it doesn’t fall off while driving.

Step 04. Reinstall the Cabin Air Filter

Now, insert the filter into the housing. Once the filter is in place, reinstall the housing and screw it back into place. Also, replace any sensors or plugs that were removed during the process. Remember to close the glove box door when you’re finished.

Following these steps will ensure that your car’s air freshener will be used correctly and will last for weeks. Thus, you’ll be able to enjoy a pleasant-smelling car without any worries.

Benefits of Adding the Air Freshener to Car’s Cabin Air Filter

Benefits of Adding the Air Freshener to Car's Cabin Air Filter

Most people are familiar with the air fresheners you can hang from the rearview mirror or clipped to the ventilation grille in the car. But installing an air freshener to your car’s cabin air filter includes a continuous source of fragrance, improved indoor air quality, and protection for your car’s ventilation system.

Continuous Source of Fragrance

The most significant benefit of an air freshener designed for your car’s cabin air filter is the continuous source of fragrance.

Unlike traditional air fresheners that only release fragrance when installed or when the scent is depleted, an air freshener added to your car’s cabin filter will release a small amount of fragrance every time the filter is cycled.

This means that you will always have a pleasant scent in your car, regardless of how long it has been since you last changed the air freshener.

Improve the Air Quality

You can improve your car’s air quality by adding an air freshener to the cabin air filter. Many traditional air fresheners rely on chemicals to generate their fragrances. These chemicals can be released into the air, causing irritation and respiratory problems for some people.

Also, air fresheners designed for your car’s cabin air filter use natural ingredients to produce their fragrances. This means they are much safer for you and your passengers and will not cause irritation or respiratory problems.

Protect Car’s Ventilation System

Adding an air freshener to your car’s cabin air filter can also help to keep the HVAC system in good working order. Over time, traditional air fresheners can cause build-up and clog in your car’s vents. This build-up can restrict airflow and eventually damage your car’s HVAC.

But, air fresheners designed for your cabin air filter will not cause any build-up or clogging in your vents. This means your car’s air conditioning system will remain clean and working correctly for longer.


Here are some frequently asked questions about air fresheners for cars’ cabin air filters:

Q: Will changing my cabin air filter make my car smell better?

It depends on what the cabin filter is made of. If it’s made of activated carbon, then changing it will make your car smell better because the activated carbon will absorb the bad smells. Changing it won’t affect the smell inside your car if it’s made of a different material.

Q: Can I Put Essential Oils On a Cabin Air Filter?

Yes, essential oil can be put on a cabin filter. The oil will evaporate and release a fresh scent into the air. Regardless, it’s necessary to ensure that the oil is safe for use in an enclosed space and does not contain harmful chemicals. Some oils may also be too potent in enclosed spaces and could cause nausea or dizziness.

Q: Can You Use Leather Scent on the Car Cabin Air Filter?

Freshen up your vehicle while providing a luxurious aroma with leather scents for car cabin air filters. Our review of the most popular leather scent for cars creates an elevated experience that will make any drive more enjoyable.

The leather scent normally comes from essential oils derived from natural sources, making them safe and non-toxic for car cabins. This scent is a popular choice for many drivers, as it helps to create a pleasant and inviting atmosphere in the cabin of their vehicles.

When using leather scents, it is essential to follow the manufacturer’s instructions for proper dilution and application methods to ensure no damage is done to the filter itself.

Q: Can I spray air freshener in my car vents?

Yes, you can spray air freshener in your car vents. But, you should not oversaturate the vents, as this could cause the air freshener to accumulate on nearby surfaces and create a mess. Also, choose an air freshener compatible with your car’s ventilation system. Some air fresheners are designed specifically for use in car vents, so these would be a good choice.

Q: Can you put an air freshener in the cabin air filter?

You can put air freshener in cabin air filters, but it’s not a good idea. Air fresheners generally contain volatile organic compounds (VOCs), which harm your health and damage the cabin air filter. VOCs can also cause the cabin filter to become clogged more quickly, reducing its ability to protect you from dust, pollen, and other pollutants.


Adding an air freshener to your car’s cabin air filter is a great way to improve the air quality in your car, protect your car’s HVAC system, and keep your car smelling fresh.

Choose an air freshener that uses essential oils and other natural ingredients to generate a pleasant scent without releasing harmful chemicals into the air.

But, you should not spray oil-based air fresheners directly on your car cabin air filter as they will clog the filter and make it less effective. Hopefully, you have found this article helpful and can now choose the best air freshener for your car.
