Filters should be cleaned at what time

2014-09-24

 　　Actually when filter is not only in how many kilometres run to clean up again and in some special cases also need to clean up, as in the sand and dust weather, after the rainy day in the muddy road, and on the sand and dirt. Because in these places the impurity particles is larger and easy to hike up it is easy to block the air filter so you need to clean up after use or completely, there is no filtering function and if every time such change is a new big cost and not filter is a new good because if there is some impurities will filter the smaller effect will be better again. Of course at the time of use enough km filter effect will be greatly decline basically have no effect so it was must be replaced if found filter mesh is broken, etc also need to be replaced.
