Cabin Air Filter Replacement: When & How to Change Yours

By AutoAnything - September 27, 2022

Like most people, you probably don’t think about your cabin air filter very often. But believe it or not, your cabin air filter plays a crucial role in keeping you comfortable while driving. So, what exactly does a cabin air filter do? Simply put, it filters the air that comes into your car. Unfortunately, this includes pollution, dust, and other airborne particles that can harm your health. Over time, these filters can become clogged with dirt and debris, so it’s essential to change them regularly. But how often should you change your cabin air filter? And what are the signs that it’s time for a replacement? To help you out, we’ve put together a quick guide on cabin air filter replacement. Read on to learn everything you need to know about changing your cabin air filter.

When to Change Your Cabin Air Filter

A few factors will determine how often you need to change your cabin air filter. For starters, the type of vehicle you drive will play a role. If you have a newer car, chances are you won’t need to change your filter as often as someone with an older model. In general, most experts recommend changing your cabin air filter every 12 months or 12,000 miles – whichever comes first. However, if you live in an area with a lot of pollution or dust, you may need to change your filter more frequently. Your filter type will also affect how often you need to replace it. For example, some filters are designed to last longer than others. If you’re not sure how often to change your particular filter, consult your owner’s manual or ask a professional.

Signs It’s Time to Change Your Cabin Air Filter

Most carmakers recommend changing your cabin air filter every 12,000 to 15,000 miles or once a year, whichever comes first. However, this varies depending on your vehicle type and how often you use your AC. For example, if you live in a dusty area or do a lot of driving in stop-and-go traffic, you may need to change your filter more often. There are a few telltale signs that it’s time to replace your cabin air filter. If you notice any of the following, it’s time for a new filter:

  • Reduced airflow from your vents
  • Strange smells coming from your AC system
  • Frequent sneezing or coughing when in the car

How to Change Your Cabin Air Filter

If you’re comfortable changing your oil or checking your tire pressure, chances are you can also handle changing your cabin air filter. In most cases, it’s relatively simple. The exact process will vary depending on your vehicle, but you’ll need to remove the old filter and insert the new one in most cases. Again, consult your owner’s manual for specific instructions. To start, you’ll need to locate your filter. In most cars, it’s located behind the glove box or under the hood. Consult your owner’s manual if you’re unsure where to find it. Once you’ve located your filter, remove it, and look at it. If it’s covered in dirt or debris, it’s time for a replacement. To install the new filter, simply reverse the process. Place the new filter in the same spot as the old one and make sure it’s secure. Then, close any access panels, and you’re good to go! If you’re unsure how to change your cabin air filter or don’t feel comfortable doing it yourself, you can always take it to a nearby auto shop and have them do it for you. It’s a quick and easy job that most mechanics will be happy to do.
