What is a Cabin Air Cleaner, and When Should It Be Replaced?

Even if you roll your windows up, particulates can still get into your vehicle. What is the best way to protect yourself from these elements? Your cabin air filter. Many vehicles with later models are equipped with one that filters the air coming into the cabin. This is the reason for the name.

These particulates may include pollen, dust, dirt, and debris that can be harmful to your health. You may find it less enjoyable to drive, but they could also make your breathing more difficult. Most modern cars have cabin air filters installed from the factory to capture and filter these particles. (Even if the vehicle does not come with a cabin air filter, it could have one.)

There are many different filters available. Some filters simply capture particulates, while others, like Electrostatic and Charcoal filters, eliminate orders with some other benefits.

Cabin air filters need to be replaced according to the manufacturer's recommendations. Typically, you will see replacement windows of 12 months, 12,000 miles, 15,000 miles. These windows are determined based upon a maintenance schedule established by the filter manufacturer. They may need adjustment depending on how the vehicle operates. You might need to replace your cabin air filter in desert-like or heavily traveled urban areas where the air quality is poor.

The instructions for replacing the cabin air filters should be found in the owner's manual. The cabin air filter is often located under your dashboard or behind the vehicle's glovebox. But some filters are hidden under the hood, making it difficult to reach.

Most cabin filter manuals would recommend checking your cabin filter at least once every year. However, you might want to replace your cabin filter if your cabin has a bad odor or isn't blowing as hard.

While it may take a while to change your cabin filter, most cases (but not all) are quick and easy.
