How to Install Cabin Air Filter

The first step to installing a cabin air filter is to purchase the right size filter for your car. You can usually find this information in the owner’s manual or on a label inside the glove compartment. Once you have purchased the correct size, open up the hood and locate where your car’s air intake is located so that you know exactly where to install it.

Depending on your vehicle, there might be two filters: one for outside air and one for recirculated air. The next step would be to remove any screws or clamps that hold down the existing cabin filter box and carefully remove it from its housing slot. Take out any other debris that may have accumulated in this area prior to installation of new filter.

Place new filter into position, making sure all sides are properly aligned within their corresponding slots before securely screwing back in place with previously removed screws/clamps or simply slide it into place if no screws are present. Finally, close up hood once complete and turn on car engine while switching between outside & recirculated air modes several times in order to ensure proper functionality of newly installed cabin air filter.

  • Locate the cabin air filter: The cabin air filter is typically located behind the glove box or under the hood of your car, depending on make and model
  • Refer to your vehicle’s owner’s manual for exact location
  • Remove existing filter: Take out any clips and screws that are holding in place the plastic cover protecting the cabin air filter and remove it from its housing unit
  • Carefully take out old cabin air filter from its slot and discard it properly (do not leave it in nature)

  • Insert new filter: Check if there is an arrow indicating airflow direction on side of the new air filter – this should be pointing towards engine compartment, otherwise airflow might be restricted once installed inside of a car – then insert new one into slot until secure fit has been achieved with no gaps between metal holder frame and paper part of a cabin airfilter itself
  • Replace plastic cover & re-install clips/screws: Put back any screws or clips that held plastic cover onto metal holder frame before replacing with a new one, making sure all connection points are securely fastened as they were before installation process begun

How to change your cabin air filter – Two Minute Tuesday

Which Way Does a Cabin Air Filter Go In?

The cabin air filter in your car is designed to help keep the air clean, and it should be changed regularly as part of your regular maintenance schedule. It is important that you know which way the cabin air filter goes in so that it can do its job properly. The correct way for the cabin air filter to go in depends on your make and model of car, but generally speaking there will be an arrow printed on the side of the filter indicating which direction it should face when being inserted into its slot.

Generally speaking, this arrow should point towards the engine or blower motor so that airflow from outside can be directed through the filter before entering through vents inside your vehicle’s cabin. Additionally, some filters may have a different orientation depending on whether they are used during summer or winter months due to their ability to provide improved filtration during certain seasons. It is important that you pay attention to these details when replacing or installing a new cabin air filter and if you are ever unsure then consulting with an automotive technician would always be advisable.

Can I Install Cabin Air Filter Myself?

Installing a cabin air filter on your vehicle can be a relatively easy process. Depending on the make and model of your car, you may have to do some research to find out exactly where it is located and what tools you will need for installation. The most important thing is to make sure that the replacement filter is the same size as the one currently installed in your vehicle.

If not, it could cause problems with airflow or even damage other components of your HVAC system. Once you are certain that you have got the right part and all necessary tools, installing a new cabin air filter should be fairly straightforward. Start by consulting either an owner’s manual or online resources specific to your vehicle if available, then disconnecting any clips or fasteners holding in place the existing cabin air filter housing cover before taking out both it and its contents.

What Happens If You Install a Cabin Air Filter Wrong?

If you install a cabin air filter incorrectly, it can have serious consequences on the performance of your vehicle. Your car’s AC system may not work properly or could even become damaged as a result. This can lead to increased fuel consumption and higher repair costs down the road.

Additionally, if you don’t replace your cabin air filter regularly, contaminants such as dust, pollen and other allergens will get into the passenger compartment; this could cause health problems for those who are sensitive to these substances. Finally, having an incorrectly installed cabin air filter can reduce airflow inside the car causing discomfort in hot weather and making it difficult to defog windows which increases safety risks while driving. To ensure that none of these potential issues arise, make sure you follow all instructions carefully when installing a new cabin air filter – or better yet – leave it up to professionals!

Can You Go Without a Cabin Air Filter?

No, you cannot go without a cabin air filter; it is an essential part of any vehicle’s climate control system. The cabin air filter removes airborne pollutants such as pollen, mold spores, dust mites and other allergens from the air entering the passenger compartment through your car’s ventilation system. Without this filter in place, these harmful particles would circulate throughout the car’s interior and can lead to respiratory illnesses or allergies for those inside the vehicle.

In addition to helping keep occupants healthy by filtering out these irritants, a clean cabin air filter also helps preserve your car’s HVAC (heating ventilation & cooling) systems since dirty filters slow down airflow which can cause strain on blower motors and make them work harder than they should. While it may be tempting to try going without a cabin air filter due to cost considerations or lack of awareness about its importance, doing so can ultimately result in more expensive repairs later on down the road as well as exposing passengers within your vehicle to unhealthy conditions every time you drive somewhere.

How to Install Cabin Air Filter


Never Change Cabin Air Filter

It is important to note that your cabin air filter should never be changed. The reason for this is because the filter serves as a barrier between you and any pollutants that may be present in the outside air. If you replace it, you will no longer have this protection and could suffer from allergies or other health issues due to breathing in these pollutants.

Additionally, changing your cabin air filter can cause premature wear on other components of your vehicle’s ventilation system which can lead to more costly repairs down the road.

Cabin Air Filter Replacement How Often

Cabin air filter replacement is an important part of car maintenance and should be done every 12 months or 12,000 miles to ensure optimal performance. A clean cabin air filter helps keep the interior of your vehicle free from pollutants like dust, pollen, mold spores and other contaminants that can cause allergies and respiratory issues. Replacing your cabin air filter regularly will also help maintain good ventilation in the car.

Car Ac Filter Replacement Cost

Replacing a car AC filter can vary in cost, depending on the type of vehicle and the parts needed to complete the job. Generally, you should expect to pay anywhere from $30-$125 for labor alone; however, this does not include any additional costs such as purchasing a new air filter or other related components. If you choose to do it yourself, be sure to check with your vehicle’s manufacturer for specific instructions and make sure that all necessary tools are available before starting the job.


Installing a cabin air filter is an easy and straightforward process that even novice DIYers can handle with ease. With the right tools, you can easily replace your cabin air filter in less than 30 minutes. Not only will having a clean cabin air filter improve your car’s performance, but it can also help keep you healthy by filtering out dust, pollen, and other allergens from the air inside your vehicle.

Taking the time to install a cabin air filter is well worth the effort for both car owners and passengers alike!
