Engine breathing should be effortless and should provide the required quantity of air. Engine performance will depend upon the quality and amount of air supplied. The air filter should be of the best quality. The selection of air filters should be perfect.

Filters are designed as per the application and conditions at the site. I will list down the air filter categories for a better understanding and selection of the filters.

Air Filter Categories

Universal Air filters

Universal air filters can be easily clamped to the air intake system. These filters are with flexibility to suit any engine. These filters are advantageous due to their low cost.

Custom Air Filters

These filters are designed as per the requirement of the engine. However, these filters are expensive compared to the universal filter but have more features than the universal filters. The owner can install these filters in the system without any hassle. They provide better filtration than universal filters. With the best filtration, these filters help in boosting the power of any diesel engine.

Paper Filters

These filters are installed in the factory. The primary function of an air filter is to filter out the dirt and high airflow to the engine. The life of the factory air filters is short and wouldn’t last lifelong. These are use-and-throw type filters. The customer has to pay from the nose. In the long run, these filters will cost heavily. The rate of filter replacement will depend upon the environment and driving conditions

Stock replacement air filters

Stock air filters are designed to suit the requirement of most vehicles on the road.  

Stock air filters are used after disposing of the factory air filters. These filters are designed to fit in the air intake box with proper sealing and without any air leakage. The best feature of these filters is that they can be reused and are washable. These filters are built with superior quality material to handle any environment and driving conditions with comfort. Usually, the design of these filters will last the lifetime of engines.

Oil bath Air filters

Oil bath filters are the old design. These filters were in practice and are still in practice for use in the air inlet side. The contaminants settle in the oil bath, and clean air is supplied to the engine

Re-usable Filters and Washable filters

The initial cost of these filters is more than the stock air filters, but owners don’t have to dispose of them off every time in the long run. These filters can be cleaned with the re-charge kit and will look as good as new. The life of these filters is longer than the stock filters. These filters are gauze or foam air filters. These filters are made from polyurethane oil-impregnated suitable for the engines subjected to the dusty and dirty atmosphere
