Febreze Cabin Air Filter UNSCENTED RZ18089 — 4‑Layer Activated-Charcoal Odor Control, HVAC-Friendly

Febreze Odor Control UNSCENTED Cabin Air Filter by PUREFLOW RZ18089 is a four-layer activated-charcoal and baking-soda filter that removes odors and airborne contaminants without adding any fragrance.

This replacement cabin air filter combines targeted odor adsorption with multi-stage particulate filtration so you get fresher, cleaner air inside your vehicle’s cabin while preserving your HVAC system’s airflow. Designed for easy, under-10-minute swaps and compatible with many Infiniti, Nissan, and Renault models, it focuses on neutralizing trapped smells—food, smoke, pet odors, and vehicle exhaust—without masking them with synthetic perfumes.

How does this filter remove odors without a scent?

The RZ18089 uses activated charcoal plus baking soda in its odor-control layer to chemically adsorb and neutralize volatile compounds rather than cover them with fragrance. This unscented approach is suitable for those sensitive to added perfumes or who prefer an unfragranced cabin environment.

• Activated charcoal captures volatile organic compounds (VOCs) at the molecular level.
• Baking soda neutralizes acidic and basic odor molecules for longer-lasting freshness.
• No fragrance additives—prevents sensory masking while eliminating the source.

Will it help with pollen, dust, and other particles?

Yes—PUREFLOW’s four-layer design traps common airborne particles that enter your car, helping reduce dust, pollen, soot, and pet dander circulating through the cabin. By capturing these contaminants before they reach the cabin vents, it can make the in-car air feel cleaner and help maintain HVAC cleanliness.

• Multi-layer media captures large and small particulates.
• Reduces pollen and dander that can aggravate sensitivities.
• Helps preserve HVAC components by catching dust and soot upstream.

Does the filter affect HVAC airflow or performance?

The RZ18089 is engineered to balance filtration efficiency with proper airflow so your heating and cooling performance remains consistent. Its construction minimizes resistance while still providing effective contaminant capture, which helps your vehicle’s blower work as intended.

• Optimized pleat spacing to maintain efficient air circulation.
• Designed to fit OEM-sized housings for reliable sealing and flow.
