The cost of replacing a car filter will depend on the type of filter you purchase. It is important to note that the filter for the air that enters the heating, ventilation and air conditioning system is different from the engine's air filter. The user manual should provide information on the location of the filter and how to open its housing to remove it. The cost may also be higher if your car is foreign or if the mechanic is charging more for a minor repair.
The cabin air filter is usually located under the dashboard and behind the glove compartment. This filter is essential in providing clean, non-toxic and non-microbial air to the vehicle. Replacing this filter yourself is often the most economical option. Generally, changing an air filter should not be expensive as it is a basic routine maintenance task for your car.
If you often drive in dirty or dusty conditions, it is recommended to check the air filter more frequently and replace it as needed. To determine if it needs to be replaced, hold it up to a light and look at it from different angles. Without an air filter, dirt, dust and other particles can enter the engine and cause blockages in the exhaust system. If you have noticed a decrease in fuel efficiency or if your engine is idling roughly and the engine light has come on, it is time to replace your air filter.
If you can smell fumes or your car emits a loud exhaust sound, it is time to replace the air filter. Filters come in different sizes and shapes specific to certain vehicles, so make sure you get one that fits your car. If you have never done this before, consult your user manual for instructions on how to find and replace the air filter. If the filter is covered with dirt or full of debris such as insects, leaves or other particles, it should be replaced immediately.
