Breathe fresh air again! As an important part of your car's heating ventilation and air conditioning (HVAC) system, the microfilter should be replaced every year or 10,000 miles. If the microfilter (cabin air filter) becomes clogged it can reduce the blower output and lead to odoriferous emissions.
Cabin filters are something that is often overlooked in vehicle maintenance, but these filters are actually very important to both your comfort and health. Traditional cabin filters prevent pollen, dust, and other allergens from entering your vehicle's cabin, keeping your air as clean as possible. Cabin filters that feature an activated charcoal filter layer take it a step further to help eliminate unpleasant smells, especially useful in large cities or when passing smelly areas such as farms.
