Febreze Febreze Odor Control HEPA Cabin Air Filter for BMW X3/330i/Z4 — Unscented, Activated Charcoal & Baking Soda

Febreze Odor Control HEPA Cabin Air Filter by PUREFLOW (RZ18151H) is a HEPA-grade, unscented cabin filter engineered to trap fine particles and neutralize odors for cleaner, fresher vehicle air.

This cabin air filter combines multi-layer filtration media with activated charcoal and baking soda to capture sub-micron particles, reduce common cabin odors, and maintain balanced HVAC airflow. Designed to be a direct-fit replacement for several BMW and Toyota part numbers, the Febreze® PUREFLOW filter is unscented so it removes smells rather than masking them, and it’s built to minimize pressure drop so your ventilation system continues to perform efficiently.

How does this filter remove odors without adding fragrance?

The filter uses adsorbent materials—high-grade activated charcoal plus baking soda—embedded in the multi-layer media to bind and neutralize odor molecules. Because it doesn’t rely on perfumes or aerosolized scent beads, it reduces smells at the source while keeping cabin air unscented.

• Activated charcoal layer captures volatile organic compounds and odors.
• Baking soda helps neutralize acidic and sulfurous smells.
• Unscented design prevents fragrance buildup or allergic triggers.
