Air cleaner filters are common devices used to clean and purify the air. They are commonly used to where there is need to recycle air. Their most popular use includes the removal of solid particles from the air so as to purify and clean the air. Air filters can clean the air of harmful microbes and bacteria as well as pollen mould and dust leaving the air cleaner and fresher.

Air filter cleaners are very important in gas turbine engines as using clean air will notably increase the efficiency of the engines.

There are many methods which are used by air cleaner filters to remove unwanted particles from the air. The most common method is to use fiber elements in the air cleaner filter to which the dust and other particulate matter will stick to thereby cleaning the air.

There are other complex methods like the static electric charge method. In this method the air cleaner filters use static electricity to attract dust and other particles thereby filtering out clean air. Oil bath filters were used earlier but now due to sophistication in technology these have fallen out of favor.

There have continued to be advancements in the air cleaner filter industry brought about by advances in fluid science. With modern air cleaner filters air conditions and gas turbines work efficiently promoting healthy human health. Some popular air filter materials include cotton filters and paper foam filters. Air filters have to be cleaned and changed regularly and periodically to get optimum performance.

Air filters fall under two categories based on their flammability. Class one and class two is used to describe the different classes of flammable air filters. Class one filters do not turn into fuel when in any contact with a flame and so produce small amounts of smoke when burnt. Class two filters become fuel when a flame is introduced and thus produce larger amounts of smoke when being burnt. Considerable amount of research is carried about the flammability of air filters.

The air filters are designed in many shapes and sizes to fit the area of flow of air. The air filters should be regularly changed as they get clogged over time filtering out air. The clogging of air filters not only produces impure air but also reduces the airflow through the passage.

For an engine this could mean serious drop in the performance of the engine. The size of the air filter also depends on the passage of air. There are different applications of the air filters but the most common application would be in internal combustion engines, gas turbines and air conditioners for both cars and rooms.

Paper is a cost effective air filter material and thus commonly used for air cleaner filters in cars. They are also very efficient and very easy to replace. Another air filter material used as automobile air filters are oil wetted foam elements. Foam was a popular common air filter material used in many applications before the advancement in air cleaning technology.
