There is much confusion concerning this filter. Many owners don't know if they need this combination filter ( both dust and oder) or the white paper element pollen and dust filter ( see related products ). In the end you will need to make the decision. We don't think anything "bad" will happen if you use either one. Watch Kent's video below for clarification. But don't be cheap and take 5 years to change it!!!

Why do these go hand-in-hand? Well if you do not change the cabin air filter(s) it is likely the dust will work its way into the blower motor and cause squeaking and chirping at low fan speeds. If that noise is ignored you will end up replacement the heater blower motor.
