Filter/Dryer

What does the filter/dryer do?

The filter/dryer is filled with desiccant; this absorbs harmful moisture and acids from the a/c system and acts as a filter similarly to an oil filter on a car engine.

Why change the filter/dryer?

After approximately 2 years the filter/dryer becomes saturated with moisture and the a/c system becomes less efficient and the cooling effect inside the vehicle decreases; there is also a risk that the desiccant can be dispersed into the a/c system causing system failure.
