What is an air filter

Air is one of the most critical steps to turning on and operating a vehicle. That said, because air is all around, the filter often stays beyond the line of thought of the average driver. The air is brought in under the hood and blends with the gasoline. The car is started with a spark from the spark plug.

If the air is not clean, dirt and other debris may get into the engine. This can lead to sloppy running and ultimately hurt the performance and longevity of the engine. The job of the air filter is to clean the air before it ever reaches the engine, picking out the particles of dust and debris.

Air filters are part of the general engine process. They are compact, light weight, and incredibly easy to change.

How Often To Change Air Filter?

Much like oil changes, there is a semi-set schedule for when to change an air filter. Basically, once per year or once every 12,000 miles for those of you that drive more than 1,000 miles per month. In dirty cities and for those that drive on dirt roads regularly, it won’t hurt you to lower that amount to every 10,000 miles.

Check the filter now and then by lifting up the hood and looking at it. When it’s browning and oddly colored, that means that the filter is getting dirty and is probably nearing the end of its useful life. If you can’t see how any air is going to get through it, the time has come for a filter change.

How does a Clean Air Filter help my car?

The biggest thing you’ll notice with a clean air filter is that the engine runs more smoothly. It is able to optimize the gasoline and air coming in, and run at optimum efficiency. As common sense would point out, the more you drive the dirtier the filter becomes. This is particularly true in cities, and dusty rural areas.

  • If the air filter is overused, it is going to block air from getting in and cause extra strain on the operating system of the vehicle. The engine will use more gas than it needs to, which hurts your gas mileage and sends you to the pump more often
  • Your engine will perform better, last longer, and ultimately increase the value of your car
  • A clean air filter reduces emissions, which is great for green living as well as passing those pesky emissions tests that so many municipalities are now requiring drivers to go through in order to register their vehicle
  • Smoother driving. When your engine isn’t full of debris, and is getting the right amount of gas and air, you shouldn’t notice hiccups in accelerating or in starting the vehicle that can be caused by reduced air flow

How to Change Air Filter

After you’ve noticed that the filter is dirty, head down to a parts store and tell the clerk you need filter for your make and model. Many grocery and convenience stores also have air filters for sale. Many will have a guide that shows you which filter will fit your car.

  • To take the used air filter out, open the box and click it out with your fingers. The box should have instructions for opening, but is usually similar to opening one of those circular mason jar type things with the clipped-on lids
  • Properly dispose of the old air filter. They can be recycled in certain situations, or put into the trash. If you aren’t sure where to put it, take it to a parts store or mechanic shop and they can advise
  • List ElementTo put the new air filter in, slide it into the box exactly how you took the old one out. If you bought the right size, it should slide right in without much trouble. Before you close the box, check to see if it’s snug. When you close the box, make sure that you latch it shut properly so that the filter doesn’t shift while you are driving
