Paper Filters vs. Synthetic Filters: Which One Is Better for Your Car?

Air filters are important to keep your car’s engine clean and safe. They can stop dirt and pollutants from getting inside the machine. Thus, you can find two common types of air filters: paper and synthetic. In this discussion, I will discuss paper filters vs. synthetic filters focusing on their features, benefits, and vice versa.

Paper filters, made from special materials, are cheaper than synthetic filters. They are good at catching dirt yet need frequent replacement. Alternatively, synthetic filters are made from synthetic and cellulose materials. They offer a longer service than paper filters but cost more than paper filters.

After reading this discussion, you can choose a better car filter. Also, you will learn about the differences between these two air filters.

Paper Filters & How They Work

You can see the use of paper filters in most cars. Car owners have been using these filters for many years. In this section, you will learn paper filters’ composition, filtration process, pros, and cons.

Composition of Paper Filters

Paper air filters are made of layers of paper or other fibrous materials like cellulose. They can remove contaminants like dust, dirt, and other particles from the air that enter the engine.

Hence, some paper filters may combine materials like cellulose fibers and resin. In these filters, the resin makes the filter robust and lasting.

Filtration Process

According to Dubizzle, these paper air filters work by using pleated paper. The fibers are thin, which allows air to pass through easily. Still, the larger surface area can capture more particles when air passes through. It ensures only clean air or fluid passes through and reaches the engine for optimal performance.

Pros of Paper Filters

You can get several benefits from using paper filters in your car. Some of them are:


Paper filters are durable. They can withstand high temperatures, pressure, and vibration in a car’s engine bay.

Moderately Efficient

These filters can capture pollutants of 5 microns or larger. Compared to their costs, they are moderately efficient in keeping the engine going well.


Paper filters are the most affordable of all types of filters. You can find them in most stores. Also, you can choose them if you want a budget-friendly air filtration option.

Easy Maintenance

You can maintain and replace these filters easily. Also, you can reuse a few paper filters by cleaning them to reduce waste and save money.

Compatible with Most Cars

You can use paper pleated filters for any car from older to the latest models. The performance will always be the same.

Environment Friendly

Paper filters are considered environmentally friendly. You can dispose of and recycle them easily.

Cons of Paper Filters

Paper filters have some disadvantages too. These are:

Less Effective than Other Filters

Compared to other air filters, paper filters are not sufficiently effective. By reusing them, these filters may pass contaminants through and damage the engine.

Become Clogged Quickly

Paper filters quickly become clogged with dirt. It reduces the airflow and restricts the performance of an engine. Also, it hampers the regular fuel economy, as AutoTrends says.

Less Durable than Synthetic Filters

You may need to replace paper filters more often. Typically, a paper filter can work effectively up to 10000 miles. (CarThrottle)

Water May Penetrate

Dry paper filters can introduce water into the engine if not properly protected with a hydro shield.

Synthetic Filters and How They Work

Synthetic filters are becoming a popular choice for their efficiency. Also, you can save more money by using them. Like paper filters, I will discuss synthetic filters’ composition, filtration process, pros and cons in this section.

Composition of Synthetic Filters

Synthetic materials like polyurethane, foam, or a combo of synthetic materials and cellulose produce synthetic filters. They may also be made from fibers like polyester or nylon. (Mospart) These materials have higher filtration efficiency than paper filters.

Filtration Process

Synthetic air filters use synthetic materials to create a more dense and efficient filtering surface. This surface helps them to capture smaller particles and contaminants more effectively than paper filters.

Pros of Synthetic Filters

Some of the advantages of synthetic filters are:

Higher Filtration Efficiency

Using synthetic filters will give you more efficient results than paper filters. They can capture smaller particles more effectively than paper filters.


You can reuse the synthetic filters by cleaning them multiple times. So, it can save more money than paper filters.

Better Durability

Synthetic filters have more resistance power to withstand extreme temperatures. They can work well in all seasons, lasting over 15000-20000 miles.

Thinner Construction

Pleated synthetic air filters are often thinner than paper air filters. So, they can let more air into the engine and make it outperform.

Easy Installation

Like paper filters, synthetic filters are also easy to install in your car’s engine.

Better Capacity

These filters can capture more dirt and contaminants than paper filters.

Cons of Synthetic Filters

You should consider these things to select synthetic filters:


The construction and efficiency of synthetic filters are the reasons why they are more expensive than paper filters. Also, replacement costs more money than paper ones.

More Maintenance

According to Mospart, these filters need more maintenance than paper filters. You may need to clean them regularly.

Not Widely Available as Paper Filters

Synthetic air filters may not suit some older car models. So, you may not find them for certain vehicles or all the stores.

Not Environment Friendly

There are concerns about the environmental impact of synthetic filters. They may take longer to decompose compared to paper filters.

Which Filter Should You Choose for Your Car? 

Choosing the right filter (between paper and synthetic filters) for your vehicle can be tough. But stay calm, as I am making it simple for you. Consider these factors:

Driving Conditions and Environment

Think about the conditions in which you primarily drive your vehicle. Synthetic filters are great if you frequently encounter dusty or dirty environments. But if you especially go in clean or urban areas, paper filters can still effectively keep your engine clean.

Vehicle Mileage

The mileage of your vehicle can also impact your filter choice. Due to the resistance, you can use synthetic filters for vehicles with higher mileage. But paper filters may work similarly but with a lesser lifespan.

Budget and Affordability

Consider your budget when selecting a filter. Paper filters are generally more affordable upfront and readily available. So, you can consider them a cost-effective choice. Conversely, synthetic filters may have a higher initial cost. But their longer lifespan and reusable nature can potentially offset the expense in the long run.


Both paper and synthetic filters are easy to install. But you will need to clean paper filters more often than synthetic filters. These filters are more prone to becoming clogged than their counterparts.

Manufacturer’s Recommendations

You should not avoid the suggestions of the manufacturer of your car or car’s engine. Otherwise, you may not get the optimal performance.

Frequently Asked Questions

Here are some frequently asked questions about paper filters and synthetic filters:

  • Are paper filters better than synthetic filters?
  • It depends on your needs and driving environment. Paper filters are generally more affordable. Alternatively, synthetic filters are more efficient and long-lasting.
  • How often do I need to replace my air filter?
  • It depends on the manufacturer’s recommendations. Generally, they recommend replacing your air filter every 10000 to 15000 miles or once a year.
  • Are synthetic filters eco-friendly?
  • Synthetic filters are an eco-friendly option as they are washable and reusable.

Final Thoughts

I hope you have better-understood paper filters vs. synthetic filters. In this discussion, I have focused on the relevant features of these filters. If you want a budget-friendly option, choose paper filters. On the other hand, select synthetic filters if you want to spend more money but get more efficient cleaning and better performance.

Thanks for being with this discussion.
