Air vs Cabin filters

Have you ever gotten confused on the difference between an Air and Cabin filter? While they are both responsible for cleaning the air that enters from the outside, the air filter cleans the air that enters the engine, whereas the cabin filter cleans the air that enters the cabin where you sit.


Air Filters

An air filter is necessary to keep contaminants such as dirt and debris from entering the engine and damaging internal engine parts, such as the pistons and cylinders. In this sense, a good quality air filter will help to prolong your engine’s service life. Clean air also sparks quicker and more efficiently inside the engine’s cylinders.

A clogged air filter increases your car’s fuel consumption and puts additional burden on the engine. Thus, it is recommended to replace your air filters around every 48,000 km or every three years, whichever is earlier.

However, it also depends on where and how you drive. If you drive in harsh dusty conditions or live in the city, you will have to change your air filter more frequently. On the other hand, you can get away with less frequent replacements if you drive your car, for example, only once a week or around the suburbs.


Cabin Filters

The cabin filter cleans the air that enters the inside of the car - the same air that you breathe in. A part of the air conditioning system, it helps prevent pollutants such as dust, pollen, haze, other airborne matter and even bad smells from coming inside the car.  If you or your family members suffer from allergies, it is important to invest in a good quality cabin filter.

It is advisable to replace the cabin filter roughly every 24,000 km to 40,000 km driven, but check your owner’s manual if you’re unsure. A sure sign of a clogged cabin filter is a musty smell coming out of the air-conditioner as you drive.
