All Genuine Toyota Cabin filters:
For Reference here is the Cabin Air Filter Chart for Toyota's and Scions.
Toyota Cabin Air Filters do an incredible job of helping to keep unwanted pollution like diesel soot, dust and pollen out of the passenger compartment. This promotes a healthier, more comfortable environment for you and your passengers. But if you’ve noticed low airflow from the heater vents, or if the windows fog up easily in “FRESH” mode, replacement is likely necessary.
Genuine Toyota Cabin Air Filters come in two styles – Regular and Premium Cabin Air Filters. Premium Cabin Air Filter are manufactured with Carbon Technology, further neutralizing odors and filter contaminants like pollen, spores and more. Consider these facts;
Poor or dirty filter can result in reduced AC/ heating /defrost functions & lower air pressure
Reduces musty odors & promotes healthier cabin air quality
Interior sealed cabins may contain concentrated amount of particles up to 6 times greater than the outside (allergens, soot, dust, etc.)
Small particles less than 10 micrometers (dust, pollen, mold, combustion particles, organic compounds, metals, etc.) pose the greatest problems.
In large congested cities and freeway traffic air pollution is higher than most other areas
Tip: Changing your air filter routinely ensures that your engine maintains the proper air flow for maximum performance. To ensure the most trouble-free operation of your Toyota, please check your vehicle’s Scheduled Maintenance Guide for proper air filter change intervals.
