Air cleaner filters are used to purify the air. This is a common piece of equipment used in cars and small rooms where there is a need of recycling the present air. Most commonly air cleaner filters are devices that remove solid particles from the air like dust pollen mould and also harmful microbes like bacteria and keep the air fresh and clean.

Air cleaner filters are used to purify the air. This is a common piece of equipment used in cars and small rooms where there is a need of recycling the present air. Most commonly air cleaner filters are devices that remove solid particles from the air like dust pollen mould and also harmful microbes like bacteria and keep the air fresh and clean.
Gas turbine engines especially need air cleaner filters as cleaner air makes them significantly more efficient.
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.
Other more complex techniques still exists like the use of static electricity. With this method a static electric charge is used to attract the particles and dust in the air. With such harmful particles removed clean air is discharged. Oil bath filters was also popular in the past before improved air filter technology phased them out.
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 can be grouped as either class one or class two air filters. The classification is done based on their flammability. Class one air filters produce a negligible small amount of smoke when burnt. They do not become fuel when they come in contact with flame. Class two filters are the exact opposite as they readily become fuel when in contact with flame. While they burn they produce significant amount of smoke. A lot of research is still being done into the flammability of air filters.
Air filter come in shapes and sizes matching the air flow area. As they work to clean the air they easily get clogged with dirt from the air. They thus need regular cleaning and changing. This clogging reduces the efficiency of the air filters, causes impure air to pas through and reduces air flow.
If this happened in an engine the result is a serious drop in engine performance. Air filters can be used for different applications and situations. Their most common usage includes use in gas turbines, internal combustion engines and air conditioners for both rooms and cars.
Paper is one of the most common materials that are used for air cleaner filters in automobiles. This is mainly because they are cost effective as well as efficient. Also these are easily replaceable. Oil wetted foam elements are also known to be used as air filters in automobiles. Foam was a known choice for air cleaners in many applications before the improvement in air cleaning technology.
