Febreze HEPA Cabin Air Filter Unscented (PUREFLOW RZ18108H) — Activated Charcoal & Baking Soda Odor Control

This cabin air filter pairs Febreze odor-neutralizing materials with PUREFLOW’s layered HEPA-style media to help keep cabin air cleaner without adding any scent. It’s engineered to capture sub-micron particles, pollen, dust, and common odor-causing molecules while maintaining balanced HVAC airflow. The unscented design is ideal when you want fresher air in the cabin without masking odors with perfumes.

How does this filter reduce odors without fragrance?

The filter combines adsorptive materials with high-efficiency particle capture so odors are removed at the surface rather than covered up. Activated charcoal and baking soda work together to bind volatile odor compounds while the HEPA-grade layer traps particulates that can carry smells.

• Activated charcoal adsorbs volatile organic compounds and smoke-related molecules
• Baking soda buffers and neutralizes common odor acids and bases
• HEPA-level media captures dust and fine particles that harbor smells
• Unscented finish preserves original cabin fragrance without added perfumes

Will this filter fit my vehicle and maintain airflow?

PUREFLOW RZ18108H is built to replace a range of OEM part numbers and fits many Acura, Buick, Cadillac, and BrightDrop models listed by year and engine. The multi-layer construction is optimized to limit pressure drop so your HVAC performance remains consistent while delivering filtration benefits.

• Replaces GM part numbers such as 13356914, 13508023, 23393247, and others
• Compatible with numerous Acura, Buick, Cadillac, and BrightDrop vehicles
• Engineered to minimize airflow restriction for reliable heating and cooling
• Installation typically takes under 10 minutes with vehicle-specific guidance

How effective is the HEPA-level filtration?

The media is designed to capture microscopic particles down to sub-micron sizes, helping reduce airborne contaminants that enter the cabin. While labeled HEPA-grade, performance depends on proper fit and maintenance—periodic replacement keeps efficiency high.

• Helps capture up to 99.97% of common particulates like dust and pollen
• Multi-layer structure separates large debris from fine particles for longer life
• Maintaining a snug fit in the housing prevents bypass and preserves filtration
• Replace according to driving conditions and manufacturer recommendations

How easy is installation and maintenance?

Installation is straightforward for most vehicles: open the glove box or the dedicated cabin-filter access, remove the old filter, and slide in the Febreze PUREFLOW unit. A QR code on the package links to step-by-step, model-specific videos if you want guided help.

• Quick swap design—many cars take less than 10 minutes
• QR code access to installation walkthroughs for specific models
• Inspect and replace more often in dusty or high-pollen environments
• Proper orientation and sealing ensure maximum odor and particle control

Who is this for: Drivers who want cleaner-smelling cabin air without added fragrances—especially owners of compatible Acura, Buick, Cadillac, and BrightDrop models who need a direct-fit, HEPA-grade replacement. It’s a good choice if you prefer odor neutralization at the source, require effective particle capture, and don’t want airflow compromised in your vehicle’s HVAC system.
