Most Subaru owners aren’t aware that their vehicle may have a cabin air filter, what it does or when to replace it. Here’s a great opportunity to help protect your customer and improve profits.

Believe it or not, Subaru introduced air filtration systems a decade ago to help purify the interior environment of its vehicles. And your customers may not have any idea that their cars are so equipped.

The air filtration system removes unwanted particles such as mold, bacteria, pollen, tobacco smoke residue and dust from the vehicle’s HVAC system. It also eliminates the bad odors associated with such contaminants. In addition, it helps eliminate odors associated with driving: exhaust fumes; environmental and industrial pollution and others (ever drive past a dead skunk or a hog farm?).

People who suffer from allergies, asthma, emphysema or other breathing problems require the cleanest air possible in their vehicles. Replacing the cabin air filter routinely can help ease these maladies.

Clogged Filters

The cabin air filter, just like the engine air filter, needs to be changed regularly to keep airflow up. Clogged or restricted air filters reduce the airflow from the vents resulting

in poor circulation. Symptoms of poor circulation include customer complaints of inadequate heating or cooling, inefficient windshield defrosting, or bad odors. The vehicle can even experience freezing of the air conditioning system if the flow does not carry the cold air through the system.

Subaru Air Filtration Systems

Beginning in 1998, air filtration systems were offered as an option on some models of Forester, Impreza and Outback Sport. The optional basis spread to some 2000 models of Legacy and Outback. By 2006, air filtration systems became standard on most models.

Where They’re Located

On most models, the cabin air filters are located behind the glove box and are easily replaced. On 1998-2003 Impreza and Outback Sport models, the filter is fitted below the glove box.

When to Replace

Cabin air filters should be replaced regularly to maintain the highest level of efficiency. If the vehicle operates in a dusty area, in humid climates, or where allergens and smog prevail, the filter should be changed more often. Extreme climate conditions, such as areas affected by blowing sand, or where forest fires have produced high amounts of smoke, require more frequent routine inspection and replacement.

When replacing a filter, don’t forget to affix the caution information and service reminder label to the driver’s door pillar. It will help remind the customer to have the cabin air filter checked and help your shop maintain the vehicle properly.

The owner’s manual lists the replacement schedule, and, usually, the replacement procedures. Point out this information to your customers to make them aware of the need to replace the filter according to the schedule. Of course, for best results, always recommend and use Genuine Subaru replacement cabin air filters.

The Best Solution

Maintaining the air filtration system is a “win-win” situation for both you and your customer. They continue to receive the benefits of clean air, better heat and air conditioning efficiency; and you get an additional boost to work orders and profit.
