How often should you change your air filter for your car?

How often should you change your air filter for your car? you change air filter for your car depending on your car driving conditions, but usually the air filter is change one every year.

Air filter is the one that cleans the air by filtering particulates that comes with the air before it goes in the engine combustion chamber. This will prevent the damage of the engine, it lessen the internal engine wear because of the contaminants present in air. During filtering of air the particulates are stocked inside air filters which then causes clogging of the air filters, that is why we need to replace our vehicle air filters.

What does a bad air filter cause?
If the engine have bad air filters for example the filter is clogged, the amount of air that the engine is needed will be insufficient because the air is restricted from entering the engine.  When there is not much air entering the engine, the effect is that the fuel will become too rich meaning there is more fuel than air in the air/fuel mixture. So much fuel is present on the air/fuel ratio.

Now what happens if the air/fuel ratio that reaches our engine is too rich? If the air/fuel ratio is too rich, there is so much gas is burned inside the cylinder, it will cause the car to emit black smoke from the exhaust.

So replace the air filters as often depend on driving conditions. If you drive on a dusty place replacement should be more often as possible. Any auto shop provides air filter in a reasonable price and it is very easy to replace air filter.
