Febreze Cabin Air Filter HEPA-Style Unscented RZ18107H — Activated Charcoal & Baking Soda Odour Control

Febreze Odor Control UNSCENTED HEPA Cabin Air Filter by PUREFLOW RZ18107H is an unscented, HEPA-level cabin filter that traps fine particles and neutralizes odors using activated charcoal and baking soda without adding fragrance.

This replacement cabin air filter blends multi-layer HEPA-style filtration with targeted odor-neutralizing media to improve the air you breathe inside your vehicle. Designed for compatibility with many makes and models — including several Lexus, Toyota, Subaru, Jaguar, and Ford vehicles — the filter balances high-efficiency particle capture with low airflow resistance. It’s engineered for straightforward installation and for preserving your HVAC system’s performance while reducing smells from sources like food, smoke, and road fumes.

How does this filter reduce odors without a scent?

The filter uses a dedicated odor-absorbing layer made from activated charcoal combined with baking soda, which traps and neutralizes odor molecules instead of masking them with fragrance. Because it adds no perfume, it’s suitable for drivers who prefer neutral cabin air or have sensitivities to scented products. The odor media works while air passes through the HEPA-like layers, so neutralization happens continuously during ventilation.

• Activated charcoal absorbs volatile odor compounds.
• Baking soda helps neutralize acidic and basic smells.
• Unscented finish avoids adding artificial fragrances to cabin air.
• Designed to function continuously with HVAC fan operation.

What level of particle filtration does it provide?

This PUREFLOW filter is built to capture particles down to sub-micron sizes, offering HEPA-level performance for dust, pollen, and many airborne contaminants. It’s rated to remove up to 99.97% of particulate matter commonly found in vehicle cabins, helping reduce the amount of irritants that circulate while driving. The multilayer design keeps filtration efficient without overly restricting airflow.

• Four-layer filtration architecture for staged particle capture.
• Targets dust, pollen, mold spores, and fine particulates.
• Maintains steady airflow with minimized pressure drop.
• Helps reduce particles that can settle on interior surfaces.

Is it easy to install and will it fit my car?

Installation is intended to be user-friendly: most replacements take under 10 minutes using simple tools or none at all. The box includes a QR code linking to step-by-step, vehicle-specific installation videos, so you can confirm the procedure for your model. The RZ18107H is a direct replacement for a long list of OEM filter part numbers and is compatible with numerous vehicle lines.

• QR-coded video guides for many vehicle models.
• Typical replacement time under 10 minutes.
• Direct replacement for many Toyota, Lexus, Subaru, Jaguar, and GM part numbers.
• Designed to preserve HVAC performance and fit OEM housings.

How does it affect HVAC performance and maintenance?

The filter is engineered to balance high filtration efficiency with low airflow restriction, helping your HVAC system maintain consistent performance. Reduced pressure drop means the blower motor doesn’t need to work harder to move air, which supports system longevity. Regular replacement helps keep vents and cabin surfaces cleaner and can improve overall comfort during drives.

• Minimized pressure drop for steady airflow.
• Supports blower efficiency and HVAC reliability.
• Replacing regularly keeps vents and interior fresher.
• Compatible with OEM housings to ensure proper sealing.
