When it comes to air filters, there are three common types: paper, gauze, and foam. Paper air filters are the most popular type used in today's cars due to their affordable price. However, they are not suitable for every car and are best for small cars and geographical areas with low pollution or dust levels. Paper filters are not reusable and must be replaced regularly.
The shape of the filter can have a significant effect on the amount of air intake potential and performance. The two most common types of shapes are panel and cone. Most factory air boxes use a panel filter, which is a flat plane. Changing the panel filter from the factory paper element to a cotton filter element can be beneficial, but changing the filter or inlet entirely can produce an even better result.
The larger the surface area of the filter, the more air can be sucked in. This is why most filters have creases or ridges; to increase surface area. Aftermarket filters often have cone-shaped pleats to further increase surface area. Most OEM filters come in the dry variety and are usually panel-shaped filters made from paper or foam material. These filters do a good job of filtering contaminants from the engine intake, but they are quite restrictive.
Once a layer of dirt is added, the restriction becomes an even greater obstacle to performance. Whether they are cotton, paper or foam, they serve the same purpose: the pleated material filters the air as it passes and retains debris and dust. For a sports car, investing in an oiled cotton filter may be the best option as it can allow the engine to breathe more deeply. However, this type of filter can cost three or more times the price of a paper filter. Since the air filter continues to accumulate dirt throughout its lifespan, it eventually becomes clogged and must be cleaned and eventually replaced. It is important to remember that your air filter is a service item with a limited lifespan that must be replaced according to your car's service schedule.
Aftermarket air filters may be even cheaper, but in the case of your car's pride and joy, the price of the air filter shouldn't be the determining factor. Wet, foam, cotton, and reusable element filters require special care, just like washable air filters, so if you don't feel like bothering, these probably aren't the best air filters for your car. Air intake modifications are popular in the tuning industry and can improve car performance; however, they are not always guaranteed. When it comes to choosing the right intake air filter for your application, it all comes down to your personal needs. The large surface area of a modern air filter ensures that it can do its job efficiently until its next scheduled replacement. It is best to stick with an original air filter as they tend to have high standards of filtration efficiency to ensure maximum engine life.
If you discover that your car's air conditioner isn't introducing as much air into the car as it used to and you have to turn on the fan to get the same amount of air as before, it could mean that your cabin air filter is blocked enough to warrant replacing it. Air filters are your car's first line of defense against dirt, dust, and other debris entering the engine; however, they only work properly when all windows are closed and air enters through the air conditioner with filter. The air filter is an often overlooked service element but is very important as it directly affects engine operation, economy and longevity. This helps deliver clean, filtered air to car occupants, especially in dusty or smoke-filled environments, and helps combat allergies. In conclusion, when selecting an air filter for your vehicle there are several factors that need to be taken into consideration such as size, shape, type (paper/foam/cotton), cost and maintenance requirements. It is important to remember that your air filter is a service item with a limited lifespan that must be replaced according to your car's service schedule in order for it to continue functioning properly.
