The 10 Best Engine Air Filters for Cars to Buy 2019

Reviews

Getting your first car is probably the best feeling in the world, right? Maintaining your car might not be as fun but it is necessary. Getting your first car also comes with a learning curve on what to do and what not to do in order to keep it running efficiently.

For the amateur, you might think that an engine air filter isn’t something you should worry about. However, it’s as important as the engine itself. Not having the correct engine air filter could actually damage your engine permanently.

The basic function of an engine air filter is to prevent debris and harmful contaminants from entering your engine. Without this, your engine could get damaged and your car will no longer be able to run.

These filters need to be changed regularly, but what are the signs to tell you when it’s time to get a new filter? Take a look at the tell-tale signs in this next section.

Features to Consider in Good Engine Air Filters for Cars

Signs You Should Replace Your Engine Air Filter

It’s recommended that you should change your engine air filter every 10,000 to 15,000 miles. However, if you’re driving in an environment with a lot of dust and air pollution, you should change your filter more frequently.

Sometimes when your car starts acting up it can be difficult to tell what the problem is. There are a few signs to look out for indicating that it might be time to replace components.

Strange Engine Sounds
If your engine starts producing sounds that it never did before, it might be something to look into. The engine should have a subtle sound and low vibration. If your car has a heavy rumble and there are loud noises coming from your engine, it might be dirt clogging your filter.

Check Engine Light
Cars are designed to tell us when something is wrong. The most common indication that your engine isn’t running smoothly is when the ‘check engine light’ turns on. However, this light turns on for various reasons. Check that your air filter doesn’t need replacing first before you assume the worst.

Misfiring
If your air filter is dirty, chances are you’ll experience engine misfiring. A dirty air filter restricts air supply resulting in some fuel not burning up. This causes a dirty residue that accumulates on your spark plugs resulting in incomplete combustion inside the engine.

When this occurs you’ll experience engine misfire, jerking and your car might not start up easily.

Reduced Acceleration
Sometimes when your car isn’t accelerating properly and the horsepower has been reduced, it could be that the engine isn’t receiving enough air flow. A blockage in the air filter can cause your car to jerk roughly when you try accelerating.

A clean air filter will increase acceleration and horsepower as it improves airflow to the engine.

The Smell of Fuel
Do you smell gasoline every time you start your car? This happens when there isn’t enough air entering the fuel injection or (carburetor for older cars) when you start the ignition. You’ll experience this when the fuel that hasn’t been burnt up exits the car through the exhaust pipe.

When this happens you’ll experience a strong smell of gasoline.

Types of Engine Air Filters

Every car comes with an engine air filter but over time the filter will need to be replaced and changed on a regular basis. There are different types of engine air filters you can purchase. Let’s discuss a few.

Paper Air Filters
These are the types of filters that will come with your car. Paper filters are made from a porous type of material that is pleated and formed into a flat panel. These filters are not durable and will perish over a short period of time.

Cotton Air Filters
A cotton filter is an oiled piece of gauze. Debris and any impurities stick to the oil like glue so none of it passes through the cotton. However, the oil can be drawn into the flow center which can cause problems.

Cotton air filters are quite durable and hardly ever need replacing. However, you will have to clean it regularly and replace the oil on the cotton.

Foam Air Filters
This type of filter is made from a special foam material that’s soaked in oil. They don’t filter as well as the paper and cotton filters. They’re usually only used in places that are extremely dusty or polluted.

These filters usually don’t have as many issues with the air flow sensors as the cotton filters do.

Metal Air Filters
Metal air filters are made from tightly woven stainless steel mesh material. They don’t need to be oiled and don’t possess the same qualities as the other filter materials do. Metal air filters aren’t capable of filtering out smaller particles of debris. This runs the risk of your engine getting damaged.

Now let’s look at a few options on the current market.

Guide to Buying the Best Engine Air Filters for Cars

Now that you know which are the best brands to buy on the market you still need to check which brands are compatible with your vehicle and consider other vital points. Let’s give you a summary on how to pick the best unit for your vehicle.

Brand Compatibility

It’s important to buy the right product that will fit your vehicle’s specifications. Although most engine air filters fit most car models it’s always wise to check and identify the correct model number of your vehicle. This helps you find the right air filter for your car.

It’s always best to purchase engine air filters that are originally manufactured for your car. This ensures that the filter fits perfectly into the housing compartment of your vehicle. The added benefit to this is it reduces any noise as the filter will be tightly fitted.

Material Used for the Surface Area

You want to purchase a filter that will trap as much debris and contaminants as possible. You will need to look at the materials made for the filter’s surface area.

The best filters to purchase are the ones that have more grooves as this design is capable of entrapping more particles and contaminants. You should avoid purchasing flat surface designs as they’re prone to be ineffective when filtering out contaminants.

Disposable Vs Reusable

Reusable Engine Air Filters
If you’re looking to save on money purchasing a reusable air filter could be an investment. They are low in maintenance and they are made with washable cotton material. With these filters, you’re able to remove them and wash them every 12,000 miles.

Reusable filters are more durable and can last up to three to four washes. However, you need to be careful with these filters as they need to be cleaned sufficiently and dried properly before reinstalling. Make sure there are no holes or imperfections before placing it back into your vehicle.

These air filters can be a bit pricey but are an overall investment.

Disposable Engine Air Filters
Disposable air filters are usually a lot cheaper. These filters need to be changed after every 12,000 miles or after a year’s use. They are usually made from resin or a durable paper that captures impurities.

These filters are not durable hence why they need to be thrown away after their lifespan is up. Failing to do so will result in the filter breaking which will expose your engine to harmful contaminants. This will damage your engine and it will cost you a lot of money to replace it.

Check your air filter regularly and change your disposable product as soon as it’s time for vehicle service.

Protection from Liquid Damage

Although air filters are designed to entrap airborne particles you should also ensure that it protects your engine from other elements as well. Purchasing a filter that’s also capable of protecting your engine from water is something you need to look in to.

When it rains heavily, the filter must be able to stop water from entering your engine.

If you also have an oil based air filter, you should make sure that the oil is dense enough not to be sucked into the engine along with the contaminants it’s supposed to prevent getting into your engine.
