No one likes to turn on their AC and see a puff of dust and pollen fly out of their vents. Genuine Toyota Cabin Air Filters make sure that your cabin is free of pollen, dust, diesel soot and other airborne contaminants. It is one of the most important parts to be replaced, especially during the spring and summer months when pollen and dust float around in the air. Genuine Toyota Cabin Air Filters keep the interior fresh and clean; and the air you breathe healthier and more comfortable! Cabin Air Filters should be changed about every 15,000 miles, depending on driving habits and environmental conditions.
