Premium Guard PUREFLOW Cabin Air Filter PC99474X — 4-Layer Activated Carbon, Toyota/Lexus Fitment

The PREMIUM GUARD PUREFLOW PC99474X is a multi-layer cabin air filter engineered to trap dust, pollen, and odors for cleaner in-cabin air in compatible Toyota and Lexus models.

If you’re replacing a cabin air filter in a recent Toyota or Lexus, the PUREFLOW PC99474X offers an upgraded four-layer media with an activated carbon layer to reduce common outside odors and capture finer particles than standard filters. Designed to fit specific 2021–2027 model years, this filter balances filtration performance with airflow to help your vehicle’s HVAC system work efficiently without restricting ventilation.

How does this filter improve cabin air compared with stock filters?

PUREFLOW uses a four-layer filtration stack where each layer targets different particle sizes and contaminants. The addition of an activated carbon layer addresses odors and volatile organic compounds commonly found in traffic and exhaust, while the other layers capture dust, pollen, and road debris.

• Four-layer media captures fine dust and larger particles separately
• Activated carbon layer helps reduce smells from traffic and exhaust
• Engineered to preserve HVAC airflow and heating/cooling performance
