How Often Should You Change a Cabin Air Filter?

If you're unclear on how often you should change your cabin air filter, there are a number of factors to take into consideration. Below are the most important things to consider before changing your cabin air filter.

How Often do You Use Your AC and Heater?

The frequency with which you make use of your car's air conditioning or heating system is one of the key factors to consider before changing your air filter. If you live in a warmer climate and use your vehicle's AC on a daily basis, you should change your filter at least once a year. Alternatively, if you live in a cooler climate and make frequent use of your vehicle's heating system, make a point of changing your air filter annually.

Do You Frequently Drive Through Smog-Laden Areas?

If smog-laden areas are part of your daily commute, this can be a determinant factor in how often you change your cabin air filter. If you spend a fair amount of time on overcrowded freeways or live in a large city, it is recommended that you change your cabin air filter once every six months. Failure to change the filter on a regular basis is liable to dramatically effect the performance of your car's heating and air conditioning.
