Car Air Filter Buying Guide

Most of the time, car owners have purchased an air filter just to replace the old one without understanding the real purpose of air filter in car and other vehicles. As mentioned earlier, this automotive component serves in cleaning the air, prior to its delivery towards the engine. Keep in mind that the operation and power of any car may suffer due to unclean and low-quality air filter. Also, the delivery of fuel can be affected negatively.

Generally, it is imperative to pick an air filter from a trusted manufacturer, considering the importance of an increased engine performance when left to substandard equipment or a disreputable brand. Among the highly recommended products include the K&N and Fram air filters.

But, the choice of automotive air filters largely depends on the vehicle owner, although the selection boils down to 2 things. It is either the buyer chooses OEM specifications, following the car model and make, or improves upon the vehicle’s level, durability, and performance.

Regardless the side of the spectrum the probable buyer falls into, a thorough comparison of air filter for cars is essential and a highly-recommended step, before any purchase.

Air Filter Types

There are three basic types of air filters for cars, including the disposable variety, the performance, and the cabin filter. Below is a brief summary of each type, giving you an adequate idea about these crucial components of your vehicle, and make an educated decision eventually.

  • Disposable Air Filter – As a discerning consumer, you will notice that the majority of automotive repair shops tend to replace a disposable filter with another, which is due to some reasons. For one, the disposable variety is cheaper than other air filter types.
    Another reason could be the long-time partnership of the auto repair shop owner with a particular supplier or manufacturer of filters. After all, the installation of disposable air filters equate to more business for the auto repair facility. But, the reduced cost is a big advantage with less complex installation for DIYers.
  • Performance Air Filter – On the other hand, performance filters for cars could last for the life of your car, although they cost more than the disposable counterparts. A performance filter is reusable, and is considered as the optimal choice for boosting a car’s performance. While the cost is quite big on the onset, it pays off eventually as it eliminates the need for future replacement.
    The fuel consumption is likewise reduced with the use of a replaceable filter, while giving out a good impact on the overall environment. Performance air filters are built to last and can withstand the car’s life simultaneously.
  • Cabin Air Filter – Cabin air filters do not only improve the overall performance and horsepower of a car, but also helps in achieving fuel efficiency. On top of that, such type of air filter is capable of protecting a car’s occupants from possible harmful contaminants. This air filter type can reduce the prevalence of unwanted elements like mold, mildew, dust, smoke, soot, pollen, and more.

Cloth Versus Foam Filters

When it comes to reusable or performance air filters, there are two essential material types that are used for advanced filtration. The materials include cloth that usually comes in multi-layers, while the other makes use of high-quality foam.

  • Cloth Filters – Performance air filters may employ multi-layers of cloth. Some car filters even use as many as seven layers of cotton-gauge cloth, which is typically contained in a specific-ridged shape through wire mesh on the sides, whereas, the mesh catches the majority of incoming particles, while the highly-breathable cloth helps in capturing the rest.
    Its pleated shape provides a bigger surface, catching more dirt and dust in the crevices and ridges. With the proper oil application, cloth filters can catch massive amounts of particles without clogging. A very popular cloth filter is the K&N VF2000.
  • Foam Filters – Meanwhile, a foam filter boasts superior breathability, which is obviously attributed to the natural material. The foam alone is 97% air, providing numerous pockets for air flow. The natural spaces in foam material make the perfect place for catching dust, while the trapping power is improved by proper oiling as well. Foam air filters allow for plenty rooms for clean airflow, while the other pockets already hold dust.

Note: Take note that the overall assembly of both materials is held collectively through polyurethane molding, a compound that is liberally applied for a strong adherence to the wire mesh and filter layers.

Why Choose Performance Air Filters?

The results of installing and using an air filter in a car may vary from one car model to the other. The engine size also plays a crucial role in the car’s overall performance. However, one can expect a range of 2% to 4% horsepower boost with the use of performance air filters. The results are also noticed instantly after the installation.

When it comes to fuel efficiency, a range between 2 and 4 more kilometers/gallon is expected due to the clean air caused by the advanced filtration of a performance air filter. The engine tends to burn fuel more efficiently with such components in a car.

Furthermore, the installation of such air filter types is very convenient as the product packages usually come in a ready-to-install design. While the installation instructions from various manufacturers may vary slightly, the general installation process is fast and simple.

In addition, most performance air filters have been engineered to be compatible with the ordinary filters they ought to replace. But, in some models of filters, an extra auto part or two may be needed or removed throughout the initial installation of the equipment. This process, however, will only ensure a perfect fit for optimum efficiency.


Choosing the best air filter brand is imperative for every car owner. Keep in mind of the boundless advantages that this automotive component offers to the car’s performance, including fuel efficiency and horsepower boost. Having an effective air filter also affects the car’s occupants, keeping them safe from harmful particles, while allowing only clean air to get through the car’s ventilation system.

All in all, there are wide ranges of vehicle air filters on the market, and choosing a specific kit must ensure the optimal cleaning solution, while a regular upkeep of this component should be guaranteed for its maximum efficiency as well.
