Car air filters are important components that help in enhancing the health and productivity of a car. It filters the air, for the combustion in the engine or the passengers inside the cabin, thus keeping the air fresh. But how many air filters are provided in a car and what role does it play? In the following discussion, we will be giving details on this topic of interest.
Types of Air Filters in Cars
Before diving into the specifics, it’s essential to understand that cars generally have two main types of air filters: Examples are the engine air filter and/or the cabin air filter. All of them are important and have their functions to play in the efficiency of the car and the comfortable driving.
Engine Air Filter
Purpose and Function
The engine air filter helps in trapping and denying access to dirt, debris, and any other particles that may be in the air to get into the engine. It makes a provision for the supply of clean air to drive the combustion process thus enabling proper burning of fuel and at the same time, shielding the engine parts from the corrosive effects of the products of combustion.Â
Cabin Air Filter
Purpose and Function
A cabin filter is assigned with the task of filtering the air that enters through the heater monitor along with the air conditioning system that is present in the cars. This aspect of it helps in excluding dust, pollen, and other small things which may be afloat in the air hence creating a clean and healthy environment for the passengers.
Engine Air Filter
Location and Installation
Usually mounted on the front side of the engine compartment, the position of the engine air filter makes it convenient to service and change. It is mostly contained in a rectangular or cylindrical container and normally can be replaced in less than five minutes.
Types of Engine Air Filters
- Paper Filters: Every day and cheap, but not imaginable to be used again.
- Foam Filters: Said to be found in performance vehicles; these can be just washed and used again.
- Cotton Filters: Susceptible to damage they come with high airflow and are compact besides being reusable.
Signs of a Dirty Engine Air Filter
An engine air filter that has not been cleaned or replaced for a long time may cause a car to use more fuel than it should or even kick, and make weird sounds, among others. Many people have reported stalling and slightly reduced power which, combined with black smoke from the exhaust, means it’s time to check the filter.Â
How Often to Replace the Engine Air Filter
Usually, the tip is to change the engine air filter after 12,000 to 15,000 miles on the road. But this depends on such factors as the external driving conditions and the kind of filter to be used.
Cabin Air Filter
Location and Installation
The cabin air filter is normally pulled from behind the glove compartment or from under the dashboard. As for changing it, this is somewhat more complicated than the case with the engine air filter, but it is still possible with basic tools.Â
Different Kinds of Cabin Air Filters
- Particulate Filters: Primarily the screens help in excluding dust and small particles.
- Activated Carbon Filters: These extend other aspects of filtration, as well as odors and toxic gases.
Signs of a Dirty Cabin Air Filter
This dirring case may signal that the cabin air filter is dirty, causing a musty smell, stale air circulation, or increased allergies. That is why it is a good practice to conduct regular inspections of the facilities with PU foam insulation.
How Often to Do a Cabin Air Filter Change
It is advisable to change the cabin air filter as regularly as most manufacturers suggest, every 15,000 to 30,000 miles or based on the model and usage of the car.
How to Check and Replace Air Filters
- Find the air filter housing in the place where all the engine-related parts are situated.
- Remove the housing cover.
- Remove the old filter and look at it.
- Replace the new filter, and it should fit correctly.
- Replace the housing cover.
How to Intake and Change the Cabin Air Filter
- This is one of the areas that require immense caution while handling; reach the filter housing that is situated at the back of the glove section.
- Take off the cover cap and the previous filter.
- Place the new filter and make sure it is properly positioned.
- Put the cover back as well as the other sections of the glove compartment.
Final Thought
In summary, a car typically has two air filters: these include the engine air filter and the cabin air filter. Both are significant for the functioning of the vehicle and the comfort of the passengers. Proper care and replacement of either of these filters may help to avoid numerous problems and deliver proper performance for the car.
