Why Your Cabin Air Filter Is Important

Whether you’re talking about the HVAC in your home or your car’s systems, one of the most commonly forgotten maintenance items is replacing the air filter. Most people think that the air filter just makes air cleaner to breathe, but they actually serve many other purposes. Your cabin air filter in your import vehicle is important, not just for your health and comfort, but also for your engine’s performance.

The Purpose of the Cabin Filter

Your cabin air filter has one primary purpose — to filter out road dust and other pollutants from the air entering the interior of your car. Outside air is sucked into the vehicle during its normal operation, and the cabin filter is how that air is cleaned.

The primary reason you want to make sure you change your cabin air filter is that it will be better for your health and comfort. A clogged cabin filter can cause an unpleasant smell in your vehicle, as well as allowing more pollutants into the air you are breathing, but it also improves the performance of your import auto.

Your AC, Blowers, and Engine

As air is pulled into the vehicle from the engine and/or AC running, it is passed through the cabin air filter. If that filter gets clogged, it creates a block for the rest of the system. The clogged filter causes the blowers to malfunction, which can cause the AC to malfunction and the engine can become overheated or overworked. 

If you want to make sure that your vehicle lasts as long as possible, you have to make sure that you are taking care of all routine maintenance. That includes replacing your cabin air filter about every 15,000 miles.
