Replacing a car's air filter is a relatively simple task that most mechanics can do in less than half an hour. An air filter is essential for protecting the engine from dirt, dust, and other materials that could clog the system or damage car parts. In the past, water and oil baths were used for air filtration, but these methods were tedious and required frequent cleaning. If you've noticed that your vehicle's performance has become sluggish, it may be because the air filter isn't working properly.
The air filter ensures that only clean air enters the engine, without dust or debris that could damage the sensors or the engine itself. If you search online for a filter for an “exclusive brand” such as BMW, you will see that more expensive filter replacements appear first. Although it may be convenient to pay someone else to do the cabin filter replacement, you can save money by replacing it yourself. There are different types of air filters for engines, but the most common are made of paper-like fibers.
The cost of replacing an air filter varies depending on the type of vehicle you have, where you buy it, and how often you change it. Most auto repair shops charge labor fees for replacing the air filter, but you can save money by doing it yourself. Reusable filters cost twice as much as disposable filters, but they can save you money over the life of your car. If you are driving in a polluted area or near the desert, it is recommended that you replace your engine filter more often as the air your engine is trying to suck in is likely to be dirty.
When dirty and not replaced in time, debris can enter the engine and affect its performance. The frequency of replacement depends on the model and how much the vehicle is driven; some require an annual replacement and others every 50,000 miles. Generally speaking, you should change your air filter every 12,000 to 15,000 miles; however, you can find a specific time period in your owner's manual.
