Designed to match factory dimensions and fit a range of Mazda 2, 3, 3 Sport, 6 and CX-5 model years, the RZ18147H installs quickly and helps reduce airborne particulate matter without adding fragrance. The package includes clear fitment notes and a QR code linking to step-by-step installation videos for most vehicles.

How does this filter reduce odors without fragrances?

The Febreze filter uses an unscented odor-adsorption layer rather than masking smells with perfumes. Activated charcoal and baking soda in the media trap and neutralize odor molecules, helping remove the source of unpleasant smells while leaving no added scent behind. This approach is ideal for drivers sensitive to fragrances or who prefer a neutral cabin environment.

• Activated charcoal layer absorbs volatile odor compounds.
• Baking soda additive enhances neutralization of acidic or sour smells.
• No perfume or scent additives—maintains neutral cabin air.
• Helps reduce lingering food, smoke and pet odors at the source.

What level of particle filtration does the PUREFLOW HEPA media provide?

PUREFLOW technology incorporates four filtration layers engineered to trap a wide range of airborne particles, including fine dust and pollen. The HEPA-grade layer captures sub-micron contaminants, helping reduce particulate load inside the cabin. The design aims to balance high efficiency with low pressure drop so HVAC performance remains reliable.

• HEPA-level capture for particles down to sub-micron size.
• Reduces dust, pollen and many airborne particulates that affect cabin air quality.
• Multiple layers combine particulate filtration with odor adsorption.
• Engineered to preserve airflow and HVAC efficiency.
