Febreze Unscented HEPA Cabin Air Filter (PUREFLOW RZ18128H) — Odour Control with Activated Charcoal & Baking Soda

This cabin air filter combines HEPA-level media with activated charcoal and baking soda to reduce odors and trap dust, pollen, and other airborne particles that contribute to stale interior air. Built with PUREFLOW multi-layer technology, it balances high-efficiency filtration and low airflow resistance so your vehicle’s HVAC system keeps working effectively. It’s made for a wide range of recent Hyundai, Genesis and Kia models and installs in most cars in under 10 minutes using the vehicle-specific instructions accessible via QR code on the box.

How does this filter remove odors without adding fragrance?

The filter uses an unscented odor-control layer that relies on activated charcoal and baking soda to adsorb and neutralize odor molecules instead of masking them with perfumes. That means no added scent, ideal for scent-sensitive riders or when you want the cabin air to smell natural after cleaning.

• Activated charcoal traps volatile organic compounds and common odor-causing gases.
• Baking soda helps neutralize acidic and basic odor compounds for balanced odor reduction.
• Unscented formula avoids chemical fragrances that can irritate passengers.

How effective is the HEPA-level filtration for cabin air quality?

PUREFLOW’s multi-layer media is engineered to capture very small particles—approaching HEPA performance—reducing dust, pollen, and many sub-micron contaminants that make interiors feel dusty or trigger allergies. The filter captures a high percentage of airborne particulates while preserving steady airflow for your HVAC system.

• HEPA-grade layer captures up to 99.97% of particles down to sub-micron sizes.
• Multiple filtration layers target different particle sizes and pollutant types.
• Design minimizes pressure drop so the blower and vents maintain reliable airflow.

Which vehicles is the PUREFLOW RZ18128H compatible with and is it easy to fit?

This FEBREZE-branded cabin filter fits many recent Genesis, Hyundai and Kia models including the GV60, multiple Elantra, Ioniq, Kona, Sonata, Tucson, Sorento, Sportage and several Niro and K-series vehicles. Installation is typically straightforward—most replacements take less than 10 minutes and the package includes a QR code linking to step-by-step, vehicle-specific videos.

• Compatible with model years across Genesis, Hyundai and Kia (detailed fitment list on the box).
• Quick install typically under 10 minutes using factory access points.
• QR code provides exact instructions for many vehicle models to simplify swap-out.

Will this filter affect my vehicle’s HVAC performance?

The filter is designed to deliver high filtration efficiency while limiting pressure drop so the HVAC fan doesn’t need to work harder to move air. That keeps cabin airflow consistent and avoids undue strain on the ventilation system, while still improving the air you breathe inside the car.

• Engineered for balanced airflow to protect HVAC performance.
• High-efficiency media with minimized resistance prevents reduced vent output.
• Regular replacement maintains both filtration and consistent airflow over time.

Who is this for: Drivers who want cleaner, scent-free cabin air—especially allergy sufferers, pet owners, and anyone sensitive to fragrances. It’s also a good choice for owners of compatible Genesis, Hyundai and Kia models who want an easy-to-install, HEPA-grade upgrade that reduces odors and airborne particles without introducing perfumes.
