Basic Climate Control Fundamentals
Filtering the Air
•
A mostly forgotten aspect of our feeling of comfort is how clean the air is. When the air is
clean it feels comfortable even at warmer or colder temperatures than normal. Add to
that the number of people today suffering from allergies (such as a pollen allergy etc.),
and the benefit of a filter can quickly be seen.
•
The filter in the HVAC ( H eating, V entilation, A ir C onditioning) system filters both the
fresh air and the recirculated air. A certain amount of smaller particles that pass the filter
are also trapped in the condensed water, which accumulates on the evaporator.
NOTE : The cabin filters used in Mazda vehicles cannot be cleaned and must therefore be
replaced at certain intervals (see the workshop manual). But if a customer drives in
dusty areas, or often drives in heavy stop and go traffic, a more frequent change
interval might be required.
