Toyota cabin air filters do a remarkable job of helping to remove undesirables like soot, dust and pollen out of the passenger compartment, and help with a more comfortable environment for you and your passengers. But if you've noticed reduced airflow from the heater vents, it may be time to replace your cabin air filter. Toyota cabin air filters are designed specifically for your vehicle and offer excellent filtering from the elements. For added benefit, Toyota offers a premium cabin air filter. In addition to all the benefits of a standard cabin air filter, the Toyota premium cabin air filter has active charcoal to help neutralize odor.
