Air Filter

Air filter is a device that is used to remove airborne contaminants such as dust, pollen, etc. We all are aware that we should change our car’s air filter regularly.

Why is it necessary to have air filter?

The air must be cleaned before it is sent to the combustion chamber. If not, we run the risk of sending dust and debris that will affect engine performance. If the debris has any sharp and abrasive material, it will wear the engine parts such as piston and cylinder.

Types of air filter:

There are various types of air filters that offer different life expectancy.

·         Paper Filter: They are the most cost effective air filter. They are also efficient and easy to service. They have to be replaced every 5000 to 8000 miles.

·         Gauze Filter: The biggest benefit of gauze filter is that they can last the entire life of the vehicle. However, they need regular cleaning with the proper air filter cleaning kit. Cotton is usually used as the gauze material. There are 2 types: oil based and dry gauze air filter. Oil based filters are more effective in filtration but will require oil, whereas dry gauze filters will not be that effective in filtration. Overall gauze filters provide a better air flow than the paper filters.

·         Foam Filter: Polyurethane foam material is used in foam filters. The foam filters can last the entire life, provided it is cleaned regularly. Just like the oil based gauze filter, foam filter requires oil. They offer minimal air flow restriction and also high dirt capacity. The high dirt capacity makes it a popular choice in off road vehicles.

·         Stainless Steel Mesh: This type allows a better air flow. Stainless steel filters provided by Hurricane is one of the best in the market.
