The cabin air filter is probably the most forgotten filter in your car when it comes to car service, and many people do not know much about it. This guide tells you why you should replace it and when it is time to do so. It also tells you where the cabin filter is located.
I work as an automotive technician and have seen what happens if people don’t replace the cabin filter. In this post, I will pass on my experience.
What is the function of the cabin air filter?
Your car takes in air from outside and blows it into the cabin directly towards you. As you may understand, there are a lot of dangerous particles and dust on the roads, and that is why we need a filter to remove these particles and dust from the road. That is the function of the cabin filter. It cleans the air before the fan blows it at you to prevent dust and particles from entering the car interior.
Why you should replace your cabin air filter
There are many reasons why you should replace your cabin filter frequently. The cabin filter is an important part of the air conditioning system to make it work properly. Here are the four most common reasons why you should replace it in good time.
1. Prevent bad smells inside the car
If you do not replace your cabin filter, it will collect dust, water, and other dangerous particles from the road. Old cabin filters can cause a bad smell inside the car when you start your fans. If the air conditioning in your car causes a bad smell, it is most likely time to replace the cabin filter.
2. Prevent condensation on the inside of the windows
The cabin filter catches a lot of water in the filter, depending on the type of car you have. Some cars collect more water, others less. However, the cabin filter of every car collects a certain amount of water and makes the filter wet. When you then turn on the fan, a lot of condensation can form on the inside of the windows, which makes it difficult to see outside. This can be a problem in colder countries, as inner condensation can lead to the windows on the inside freezing in winter.
3. Keep the value of the car
Many people look at the service history of a car before they buy it. If they find out that the cabin air filter has never been changed, they may think that the maintenance of the car is poor and will either want a lower price or may not even buy the car at all. Car dealers also pay attention to this when they check your car before buying it. Always write in the maintenance history when your cabin filter was replaced.
4. Keep the AC system working properly
Water and dust from an old and bad cabin filter can cause condensation inside the air conditioner and damage electric motors and other parts inside. By replacing the cabin filter frequently, you can prevent this and probably save a lot of money in the long run. Changing the cabin filter is probably cheaper than replacing the electric motors.
When should you replace the cabin air filter?
To know when to replace the cabin filter, you must consult the manufacturer’s repair manual or call your dealer to get the correct information for your vehicle. I recommend that you change the filter every year or every time you service your car. Many car manufacturers like Volkswagen, BMW, and Audi have 3000 km or 24 months between changing the cabin filter. To keep your cabin filter and your car in the best condition, I recommend that you change the filter at least once a year. Most cabin filters are quite cheap and easy to replace.
Where is my cabin filter located?
The position of the cabin filter depends heavily on the type of car you have. It is generally located near the air conditioning fan of your car. In some cars, it is located under the windscreen cover, in others under the dashboard. In many cars, you will need to remove the glove box to access the filter. Many filter manufacturers will give you instructions where the filter is located in your car when you buy the filter.
Generally, in many Asian cars, the filter is installed behind the glove compartment, and in some cases, the glove compartment must be removed to replace the cabin filter.
What happens if I do not replace the cabin air filter?
If you do not replace the cabin filter, you will get the symptoms mentioned above. You may notice bad smell and condensation on the inside of the windows. The value of your car may decrease and you may even damage parts inside the air conditioner.
How much does it cost to replace the cabin air filter?
The cost of replacing the cabin air filter is often quite low. The price of the filter is often between $10-30, and in most cases, the replacement is done in a maximum of 30 minutes.
