Febreze Cabin Air Filter UNSCENTED PUREFLOW RZ18109 — Activated Charcoal & Baking Soda Odour Control, Direct-Fit for Honda/Acura

Febreze Odor Control UNSCENTED Cabin Air Filter by PUREFLOW RZ18109 is an unscented, activated-charcoal cabin filter engineered to absorb and neutralize car odors while trapping dust and airborne particles without adding fragrance.

This replacement cabin air filter from Febreze uses PUREFLOW multi-layer filtration with activated charcoal and baking soda to target unpleasant smells at their source while also capturing pollen, dust, and common urban pollutants. Designed as a direct-fit part for many Honda, Acura and MG models, the RZ18109 keeps HVAC airflow balanced and installs in minutes using vehicle-specific guidance accessible via a QR code on the packaging.

How does this filter remove odors without masking them?

The RZ18109 relies on adsorption and neutralization rather than scent additives. High-grade activated charcoal provides porous surface area to capture volatile organic compounds and baking soda helps neutralize acidic and basic odor molecules, so unpleasant smells are reduced rather than covered up.

• Activated charcoal adsorbs a wide range of gases and VOCs.
• Baking soda chemically neutralizes odor-causing molecules.
• Unscented formulation avoids perfume reactions or headaches.
• Works continuously as air passes through the cabin intake.

Will this filter affect my car's HVAC airflow or performance?

PUREFLOW filtration is engineered to balance efficiency with airflow so your HVAC system maintains performance. The multi-layer construction traps contaminants while preserving consistent circulation, minimizing strain on the blower motor and keeping defrost and climate control responsive.

• Four-layer design for filtration without excessive resistance.
• Maintains manufacturer-intended airflow rates for most models.
