Oil filter, air filter, fuel filter and air conditioning system are all parts of the auto maintenance in the vulnerable parts, replacement frequency is relatively high.

This is the case, the filter is very important, and how to avoid the inferior products are not careful "in the bag", what are the hazards of inferior products?

Poor quality oil filter will cause serious engine wear
The role of oil filter is from oil bottom shell oil harmful impurities filtered, to clean the oil supply of the crankshaft, a connecting rod, a cam shaft, turbocharger, piston ring, such as motion side pieces to the lubrication, cooling, cleaning effect, thus extending the life of these parts. If you choose the inferior oil filter will make the impurities in the oil into the engine compartment, and ultimately lead to serious engine wear and need to return to the plant overhaul.

Oil filter usually does not need to be replaced separately, only the oil filter is recommended to replace the oil when the replacement can be.

Poor quality air filter will increase fuel consumption to reduce vehicle power
There are all kinds of foreign bodies in the atmosphere, such as leaves, dust and sand etc.. These foreign bodies if entering the engine combustion chamber will increase the engine wear, thereby reducing the engine's service life. An air cleaner is a part of a vehicle that is used to filter the air entering the combustion chamber. If you choose a bad air filter, will increase the intake resistance, engine power down. Or increase the fuel consumption, and it is easy to produce coke.

Air filter service life, according to the local air conditions are different, but the longest no more than 1 years, the distance of the vehicle is not more than 1.

Poor fuel filter will cause the vehicle can not be started

The function of the fuel filter is to remove the solid impurities such as iron oxide and dust in the fuel oil, so as to prevent the fuel system from clogging (especially the fuel injection nozzle). If the use of poor fuel filter, fuel impurities in the filter can not be effective, it will lead to blockage of the oil, the vehicle will be unable to start due to lack of fuel pressure.

Poor air filter prone occupants sick

The main function of the air conditioner filter is to filter out all kinds of particles and poisonous gas in the air of the ventilation system of the air conditioning system. Image points, it is like a car breathing "lungs", to transport the air inside the compartment. If the use of poor quality air filter is equivalent to put a bad "lung", unable to effectively isolate and remove toxic gases in the air and level is easy to moldy breed bacteria, long-term in such an environment, the health of themselves and their families will cause bad influence.

Generally speaking, the air conditioning filter to change once a year is enough, if the air dust can be reduced to shorten the cycle of change.
