Understanding car air filter

A car air filter may not appear to be a necessary component to check and replace on a regular basis, but it is critical to the operation of your vehicle. The filter keeps tiny particles from entering the engine and inflicting costly damage.

Well, in this article, we’ll delve deep into the air filter, as the answers to the following questions will be discussed:

• What is an air filter and its functions?
• What are the benefits of an air filter?
• Where are the engine air filters located?
• What are the symptoms of a bad and failing air filter?
• How often should you change your car’s air filter?
• How much do engine air filters cost?

Ok, let’s get started!

What is an air filter and its functions?

An automobile, like humans, requires oxygen to breathe and for the combustion process. The air filter keeps insects, dust, particles, sand, and debris out of the engine and maintains a suitable air-fuel mixture for performance. Car air filters come in a variety of designs, including panels, circular, and cylindrical.

They are made of a pleated material that filters the air, which might be cotton, synthetic paper, or foam. An automobile typically has two air filters. The first is for the engine, and the second is for the cabin. Both air filters are equally important for the car’s performance.

This is why it is critical to keep an eye on them. Because they are permeable, the filter screens are constructed of paper, cotton, or foam. They must, first and foremost, prevent sand, dust, pollutants, and even mold from entering your car’s engine system.

• Engine filters: The purity of the air entering the engine improves its performance. The engine’s cylinder walls and pistons will be harmed if the screens are not present in the engine system. If something goes wrong, contact an engine repair shop.
• Cabin Filters: High-quality cabin air filters capture dangerous emissions from the vehicle, safeguarding the driver’s health. Air pollution is a key cause of cardiovascular and respiratory disease, which is why car cabin air filters are critical.

What are the benefits of an air filter?

A car air filter is beneficial to the engine in a lot of ways. Here are a few of the many benefits of the air filter in a car engine:

• Improved fuel economy.
• Emissions reductions.
• Extends the life of the engine.

Improved fuel economy

Depending on the make and model of your vehicle, replacing a clogged air filter might enhance fuel efficiency and acceleration. When you realize this, it makes sense to change your air filters on a regular basis. What is the importance of an air filter? A clogged or damaged air filter reduces the amount of air that enters your car’s engine, causing it to work harder and consume more fuel. Because your engine requires more than 10,000 gallons of oxygen to burn every liter of fuel, it’s critical not to impede this airflow.

Emissions reductions

Dirty or broken air filters limit airflow to the engine, altering the air-fuel balance in your vehicle. This imbalance can clog spark plugs, causing the engine to miss or rough idle, as well as increase engine depositions and turn on the ‘Service Engine light. More importantly, the imbalance has a direct impact on your car’s exhaust emissions, which contribute to pollution in your surroundings.

Extends the life of the engine

A particle as small as a grain of salt can pass through a clogged air filter and cause significant damage to internal engine components such as cylinders and pistons, which can be costly to repair. That is why it is critical to replace your air filter on a regular basis. A clean air filter is intended to trap dirt and particles from the outside air, preventing them from entering the combustion chamber and lowering the likelihood of a significant repair expense.

Where are the engine air filters located?

The engine air filter is normally located in the engine compartment, either in the front or along the side of the engine, inside a rectangular or square-shaped housing. It may be encased in a black plastic or metal housing and secured with clips or screws. The cabin air filter is usually situated beneath the glove box or behind a cover that may be accessed from the engine bay via the front windshield.

If you know where the blower motor is, look there! In many Asian vehicles, the filter is often positioned beneath the glove compartment, and in some cases, the glove compartment must be removed to change the cabin filter. In European cars, it is frequently veiled beneath a cover behind the front windshield from the engine area.

What are the symptoms of a bad and failing air filter?

If the air filter is going bad in a car, the following are the most common symptoms you’ll notice:

Failing engine air filter:

• Engine Performance Issues.
• Poor Acceleration.
• Check Engine Light (Illuminated).
• Unusual Engine Noises.
• Tailpipe Producing Black Smoke.
• Reduced Gas Mileage.
• The Engine Air Filter Is Visibly Clogged.

How often should you change your car’s air filters?

Naturally, if your air filters are damaged, they should be replaced. However, to keep your automobile running at peak performance, replace your cabin air filters every 12,000 to 15,000 miles or once a year, whichever comes first. Engine air filters should be changed every 30,000 miles or as recommended by the owner’s manual for your vehicle.

If you frequently drive in dusty circumstances, you should shorten this interval. For the recommended replacement schedule, consult the manufacturer’s maintenance plan. It is simple, quick, and inexpensive to replace an air filter.

However, there are numerous air filters on the market, and it is critical that you select the correct one for your vehicle’s make and model. Check your owner’s manual to determine which type you require and where it is situated in your vehicle. Find out how simple it is to change your air filters here.

How much does it cost?

The average cost of replacing an engine air filter ranges from $20 to $85, depending on whether you go to a mechanic or do it yourself. This pricing range is based on national averages for all vehicles and excludes taxes, fees, and your specific make and model. Repairs or maintenance on related components, such as the cabin air filter, may also be required.

Changing the cabin air filter normally only takes a few hours of work and can be done in under 30 minutes. The typical cost of changing a cabin air filter ranges from $40 to $100, depending on the model of the automobile and labor charges.

A cabin air filter can also cost between $20 and $50, depending on whether it is charcoal or normal. If you choose a charcoal cabin air filter over a regular one, the price may change slightly. Charcoal filters would be more beneficial to allergy sufferers because they filter the air more thoroughly.
