Things to Consider When Buying the Best Car Air Filter

You can evaluate the following factors before making any decision. With the following information, you can make a better choice.

Filter Size

Before you shortlist any air filter, it is important to consider the size of the filter. The size should fit your air filter system and the model of your engine. 

Most of the available filters have the size printed on the side. However, the figures are often a rounded measurement. That means they are undercut by up to half an inch of the precise size. 

You can use a measuring tape to get the exact measurement of the height, depth, and width. This way, you can ensure that you do not buy any misfits that may turn out to be useless.

Filter Model

It is vital to consider the filter model before shortlisting some products that can be the best car air filter. That is because the model decides the fitness, depth, width, and height of the filter. 

Also, knowing the model can help you in finding the right filter quickly. On the other hand, Many manufacturers design filters to fit specific engine models. Additionally, they will help you sort the wide range of filters that are available in the market.

After-market or OEM

Original filters are car air filters that the manufacturer of your vehicle specifically builds to fit the model. Original Equipment Manufacturer parts (or OEM) is another name for original filters.

On the other hand, after-market filters are air filters manufactured by various other manufacturers to fit the model. After-market, filters are manufactured with the same design as the original. Also, they are usually cheaper than the original, yet they provide the same level of quality. However, some reputed after-market brands provide better quality air filters than the original.

SAE testing and approval

Car air filters are subjected to tests to ensure they meet the engine manufacturer’s requirements. After the evaluations, if they meet those requirements, they are approved by the SEA or Society of Automotive Engineers. 

The filters are rated based on the following factors after the testing. They are the amount of dirt and debris they can trap, how long the filter can last before clogging, and its efficiency.

Micron Rating

The air filters are made of microscopically small pores measured in microns. 

A micron is a unit of measurement that is one-millionth of a meter. A human hair is about 50 microns. 

The density, thickness, number of pleats, and micron size decide the quality of an air filter. The lower the micron rating, the higher the ability of the filter to trap dirt and abrasives.

Filter Mileage

The best car air filter will ensure efficiency and ensure mileage if you use a superior quality air filter. You do not have to change it as often as other filters. 

Also, a high-flow air filter can enhance the horsepower of your vehicle by 2 to 5 HP. They can increase the torque and fuel efficiency, and this means better mileage for your vehicle.

Environment

The environment in which you drive around your car impacts the efficiency of the air filter. If the place you live in is unusually dusty, you should always choose a better quality filter than someone who lives in a place that is not as dusty. 

You must also consider better quality filters if you live near a beach, gravel or dirt roads, or a highly polluted city. Hence, always consider your environment, whether you live in the countryside or a city, before picking the best car air filter.

These types of filters require more service time than other vehicles. Nevertheless, they do not waste a lot of your time.

What happens if I don’t replace the car air filter regularly?

As the filter gets old, it will become too dirty and will get clogged. That will result in the filter blocking the air required for the combustion chamber. If you do not change the car air filter regularly, there are many consequences.

Additionally, this may lead to some unburnt fuel leaking through the exhaust pipe. That may give out a fuel smell when you start the vehicle.

Let's Wrap Up

Dust particles may be as small as a sand grain; they still can damage your engine, costing you hundreds of dollars. Hence, maintaining your car with care by regularly replacing the air filter can prevent those damages.
