Premium Guard HEPA Cabin Air Filter for Mercedes‑Benz 2016–2026 (PC99241HX) — HEPA + Activated Charcoal

Premium Guard PUREFLOW PC99241HX is a HEPA-grade cabin air filter engineered to trap fine particles and reduce odors for cleaner interior air in compatible Mercedes‑Benz models.

When you want noticeably cleaner air inside your Mercedes-Benz without changing the HVAC system, this PUREFLOW cabin filter pairs high-efficiency HEPA media with an activated charcoal layer to address both particles and smells. It replaces the factory cabin filter in a range of 2016–2026 Mercedes models, offering improved filtration for pollen, dust, soot, and traffic-related odors while remaining designed to fit the OEM housing and airflow characteristics.

How effectively does it remove fine dust and allergens?

The PUREFLOW PC99241HX uses HEPA-grade media that targets very small airborne particles down to about 0.3 microns, which helps reduce visible dust and many common allergens inside the cabin. While not a medical device, its dense media significantly reduces particulate load compared with many standard cabin filters.

• High-efficiency HEPA-grade fibers capture fine particulates.
• Designed for sub-micron filtration to reduce visible dust in vents.
• Helps lower pollen and common allergen levels in the passenger compartment.

Will it help with odors and vehicle fumes?

An integrated layer of premium activated charcoal adsorbs traffic fumes, exhaust odors, and many strong environmental smells that can enter the cabin. It does not chemically neutralize gases, but it reduces odor intensity by trapping odor-causing molecules on the charcoal surface.

• High-grade activated charcoal layer for improved odor control.
• Reduces intake of road and city traffic smells into the cabin.
• Good choice for drivers frequently in heavy traffic or urban environments.

How does installation and compatibility work with my Mercedes?

The filter is manufactured to match OEM dimensions and fitments for specified Mercedes-Benz model years, making installation a direct replacement in the factory cabin filter housing. It’s intended to work with the vehicle’s climate system without modification; depending on usage and conditions you may notice a very slight airflow change due to the denser media.

• Direct-fit replacement for listed 2016–2026 Mercedes models.
• Installs in the existing cabin filter compartment—no tools beyond basic access required.
• May introduce a minor airflow restriction because of the denser HEPA media.

How often should I replace the PUREFLOW filter?

Replacement frequency depends on driving conditions: city driving, heavy traffic, and dusty or pollen-heavy regions will require more frequent changes than light, clean-air use. As a practical guideline, inspect the filter at routine service intervals and replace it when visibly dirty or per the vehicle manufacturer’s recommended schedule.

• Check filter at regular service intervals or annually as a baseline.
• Replace sooner if you drive in polluted, dusty, or high-pollen areas.
• Look for visible discoloration, dust buildup, or reduced HVAC performance.

Who is this for: Drivers of compatible Mercedes‑Benz vehicles who want upgraded cabin filtration—especially those sensitive to dust, pollen, or traffic odors—will benefit from the PUREFLOW PC99241HX. It’s suited to commuters, families, and anyone who prefers cleaner interior air while maintaining a direct-fit, professional replacement for their factory cabin filter.
