My car needs.A/c filter

What happens when you do not change cabin air filter/Passenger compartment air filter.

This filter has many name references.

Change your A/C filter or pollen regularly and breath clean air. Pollen filters get dirty therefore restrict good air circulation.

Signs of bad A/C filter

.Bad smell when you turn on A/C

.Restricted air flow

.Whistling noise

. Pollen and contaminated air not filtered causing sinus trouble to occupants that have allergy troubles

.Poor window fog clearing
