Febreze Cabin Air Filter PUREFLOW RZ18146 Unscented — Activated Charcoal & Baking Soda, 4-Layer Odor Control

Febreze Odor Control UNSCENTED Cabin Air Filter by PUREFLOW RZ18146 is an unscented activated-charcoal cabin filter engineered to trap dust, pollen, gases and neutralize odors without adding fragrance.

If you want cleaner, fresher interior air in your vehicle without perfumed masking agents, this Febreze PUREFLOW cabin filter offers four-layer filtration that captures particulates and adsorbs odor-causing compounds. Designed to replace specific Audi, Volkswagen and SEAT cabin filters, it maintains HVAC airflow while targeting the chemicals and organic odors that accumulate in a car’s ventilation system.

How does this filter remove smells without using fragrances?

The filter combines activated charcoal with baking soda and a multilayer media to adsorb and neutralize volatile odor molecules rather than covering them with scent. Because it’s unscented, it won’t clash with personal fragrances or cause headaches for scent-sensitive passengers.

• Activated charcoal layer traps gases and volatile organic compounds (VOCs)
• Baking soda component helps neutralize acidic and basic odor molecules
• Multi-layer media captures pollen, dust, soot and pet dander
• Unscented design leaves air truly fragrance-free

Will this affect my vehicle’s HVAC airflow or performance?

PUREFLOW filters are engineered to maintain balanced airflow so the heating and cooling systems continue to operate efficiently. The media density is selected to filter contaminants without creating excessive resistance that could reduce ventilation performance.

• Tested for consistent, reliable airflow through vehicle HVAC ducts
• Four-layer construction balances filtration and pressure drop
• Does not require HVAC system modifications
• Typical replacement takes under 10 minutes on compatible models
