Febreze HEPA Cabin Air Filter — Unscented PUREFLOW RZ18109H, Odour Control & Activated Charcoal

Febreze Odor Control UNSCENTED HEPA Cabin Air Filter by PUREFLOW RZ18109H is a fragrance-free, HEPA-grade cabin filter that removes fine dust, pollen and odor-causing particles to help restore cleaner-smelling air inside compatible vehicles.

Engineered with PUREFLOW multi-layer media, this cabin filter combines HEPA-level filtration with activated charcoal and baking soda to capture sub-micron particles and absorb odors without adding any scent. The design balances high-efficiency particle capture with low pressure drop so your HVAC system maintains reliable airflow. It replaces several OEM Honda part numbers and fits a broad range of Acura, Honda and MG models from recent years.

How does this filter reduce odors without fragrance?

The Febreze UNSCENTED filter traps particles while neutralizing odor molecules instead of masking them with perfume. Activated charcoal provides adsorption of volatile compounds and baking soda helps neutralize acidic and basic odors.

• Charcoal layer adsorbs volatile organic compounds and smoke residues.
• Baking-soda layer helps neutralize a range of odor sources.
• Unscented finish keeps cabin air free of added fragrances.

Will this filter improve the air quality in my car?

Yes — the PUREFLOW media is designed to capture up to 99.97% of dust and pollen down to sub-micron sizes, reducing airborne particulates that contribute to stuffy or dusty cabin air. Cleaner filtration reduces visible dust accumulation and helps your HVAC circulate clearer air.

• HEPA-grade layer targets fine dust, pollen and other small particulates.
• Four-layer construction balances filtration efficiency and airflow.
• Designed to minimize pressure drop so vents remain responsive.

Is it difficult to install and which vehicles does it fit?

Installation is straightforward and typically takes under 10 minutes on most vehicles; the box includes a QR code linking to vehicle-specific installation videos. The filter replaces multiple Honda OEM part numbers and fits a long list of Acura, Honda and MG models across recent model years.

• Scan QR code for step-by-step, vehicle-specific video instructions.
• Most replacements require basic tools and no advanced skills.
• Compatible with many Acura and Honda models plus MG3 (see product fit list).

How does the filter affect HVAC performance?

PUREFLOW filtration is engineered to provide high capture rates while maintaining optimal airflow, helping avoid the increased blower strain that can occur with denser filters. That balance supports consistent cabin ventilation and temperature control.

• Low pressure-drop design maintains efficient airflow through ducts.
• Helps ensure HVAC system operates without excessive blower load.
• Regular replacement preserves airflow and filtration performance.

Who is this for: Drivers who want a fragrance-free way to reduce dust, pollen and odor-causing particles inside their vehicle — especially owners of compatible Acura, Honda and MG models seeking HEPA-level capture without added scent. It’s a practical upgrade for allergy-prone riders, families, daily commuters and anyone who prefers neutral-smelling cabin air while maintaining efficient HVAC performance.
