What Is the Function of Engine Air Filters?

In automobiles, air from the atmosphere is taken to produce the air-fuel mixture which is burnt to produce power. The atmospheric air contains dirt, dust and pollutant particles in it. These harmful particles cannot be taken through the air intake system inside the engine.

The soot particles, oil, dust and pollutant lead to scale formation inside the engine and reduce the working capacity of the engine. To prevent these troubles, engine air filters are installed in the air supply system of the engines. The filters arrest the dirt, dust and debris contained in the air and let only the clean portion of the air particles go through.

Briefly, function of engine air filters is filtering the dirty air and providing the engine clean air which is free from dirt, dust and pollutants.

What to Consider Before Buying Engine Air Filters?

There can be various shape, size and models of engine air filters availed in the market if anyone checks, but the user needs to choose the proper one for his vehicle. We are going to discuss some criterion here based on which the decision should be taken.

The Model of the Vehicle

There are various shapes and sizes of air filters but your vehicle needs a particular size and shape. Compatibility of the air filter with your engine must be checked. This is not a big problem these days as air filter manufacturers also specify the compatibility information with the filter model both online and on the packet of the filter.

Temperature Resistance

The working temperature of the engine and the atmospheric temperature affect the performance and longevity of the filter. The user must check whether the filter is able to serve in the geographic area where the vehicle is used.

Surface area

The engine air filter is used to trap the maximum of the dirt and debris from the intake air. The more the surface area of the filter, it could trap more of the unwanted particles. That is why the engine air filters are pleated. If the user can avail an option of engine air filter with maximum surface area that fits in his engine, he definitely should go for that one.

Weather conditions

The weather conditions like atmospheric pressure and the moisture in the air affects the working of the filter. Also the working pressure of the engine affects the performance and lifetime of it. The user should keep these things in mind.

Price

Engine air filters require frequent changings, so the economic point of view comes up. One should opt for an air filter for his engine, which possesses all the above requirements and has the best suited pricing as well.

How to change engine air filters?

By this far of discussion, you should know that the engine air filters generally need frequent replacements. The method of changing the engine air filter will be different for the different engine models. The manufacturer provides necessary instructions in the owner’s manual of the vehicle about it.

Though the various air filters of the engine fit in different methods, the general approach to change them is the following:

  • First step is checking out whether the filter’s life has ended and whether it needs replacement. The filter should be removed from the air supply line of the inlet manifold and checked for it manually
  • The replacement for the worn out filter should be selected carefully gathering all the information required. The proper model should be obtained
  • In order to remove the filter from the car it should be parked in a proper area having the car locked and the engine shut. The hood of the car should be opened using the lever inside car
  • The air box is now to be located, usually in modern vehicles the air box housing can be found near the engine along a duct travelling from the car’s front end
  • The air filter cover is now to be removed. There should be hose clamp that seals the air conduit. Air filter cover should be removed undoing the screws. There can be wing nuts depending on the car model or elsewhere the filters are just clamped with quick release system.
  • The nuts and cover removed from the air box housing should be kept in a safe flat surface. Then the air box cover is to be pulled out so it comes to the lower part of the housing.
  • At this point, the filter should be seen of round, rectangular or any other shape. The filter should just simply be removed from the housing. Removed filter should be cleaned if it is washable or reusable before installing it back
  • The housing should now be cleaned properly. After cleaning the housing, the new replacement filter should be installed in the housing
  • Now the air filter cover should be kept back to its proper position from where it was removed. Air filter cover should be fitted the way it was before using the screws or nuts. Now the air box cover should be pushed to lock it in its position

This entire process can be found as tutorial in YouTube videos as well as in visual instructions in the owner’s manual book. Help from experts or mechanics should be taken in case the owner is not comfortable or unsure whether he can perform this replacement.

How outdated engine air filters affect engine performance?

The air intake system of the engine works as the nose of the engine. As human use their noses to breathe, the air intake system is quite the same in the case of engines. The engine air filter is most essential to ensure that in this breathing of engine only clean air is inhaled.

The use of outdated engine filter affects engine performance greatly as we are discussing now:

  • The outdated filters do not have sufficient filtration capacity, so the dirt and dust particles pass through it. In the long run, this dirt and debris may form scaling inside engine affecting its performance
  • Due to formation of scaling caused by improper filtration by outdated filters, the engine may need more servicing and raise the maintenance cost
  • The outdated engine air filters may contain unwanted particles trapped with its surfaces, which block the entrance of fresh air. This may cause a reduction in the rate of air flow to the engine
  • Outdated engine air filters cannot help to supply required amount of pure and fresh air to the engine. This in turn decreases the power output and performance of the engine
  • Outdated filters let undesirable particles inside engine, so the components of the engine are affected and may have damage
  • As outdated filters lead the engine to produce lesser power, to generate required amount of power more fuel is needed. This decreases the mileage of the engine

How to know if engine air filter is not working properly?

There are always recommended intervals from both the vehicle and air filter manufacturers about the frequency of changing air filters of engine. However, there are some symptoms that help you understand if your filter has some trouble.

  • The mileage of the vehicle will decrease due to dirty or improper functioning filters. This will lead to more fuel requirement
  • The power produced by the engine will decrease. Same can happen in the case of speed of the engine
  • There can be some missed firings in engine cylinder
  • For the same speed generation, more rpm of the engine will be required
  • There may be some noise instead of smooth air suction sound of the engine

It is always recommended to clean and check the condition of the engine air filters in intervals prescribed by the manufacturers.

How frequently Engine Air Filters need replacing?

The air filters of engines need frequent replacement comparative to most of the other parts of a vehicle. Mostly the changing interval depends on the run time of the vehicle. In a common way it can be considered that, the more mileage the vehicle covers, the sooner the filter will need replacement.

However, the vehicle manufacturers have broad researches on this issue and they generally suggest the frequency of the replacement of this part. The manufacturers commonly provide this frequency based on the mileage of the vehicle covered as well as the time period.

Generally, the filters need to be replaced after 12,000 miles of vehicle running. Also an idle vehicle will need the replacement of engine air filter in 6-12 months of period as mentioned by the manufacturer. The filters may also not function properly due to uncertain reasons.

Best way to decide whether the engine air filter needs replacement or not is to dismount it from air supply system and check it manually whenever the user suspects of ineffective functions of the filter.

Some Frequently Asked Questions (FAQs)
