Premium Guard PUREFLOW Cabin Air Filter PC99011X for Mercedes‑Benz GLA/CLA/B/A (Activated Carbon, 4-Layer)

This Premium Guard PUREFLOW cabin filter replaces factory units in a range of Mercedes‑Benz compact models and similar platforms. Built with four filtration layers including an activated carbon media, it reduces airborne particles and helps control common outside odors before air reaches your vehicle’s ventilation system. The PC99011X is made to match OE fitment and airflow characteristics so your climate system continues to perform as designed.

How will this filter affect the air inside my car?

The PUREFLOW PC99011X captures fine dust, pollen and road debris across a multi-layer media and reduces nuisance smells with an activated carbon layer. It does not treat medical conditions but improves general cabin air quality compared with a worn or absent filter.

• Four-layer filtration catches particles of varying sizes.
• Activated carbon layer reduces common outdoor odors.
• Maintains consistent airflow for HVAC performance.

Which vehicles does PC99011X fit and how do I verify fitment?

PC99011X is engineered to fit specific Mercedes‑Benz models from 2013–2020 including GLA250, CLA250, B250 and a variety of A‑ and CLA‑class engines, plus the INFINITI QX30 platform. Always confirm with your vehicle’s filter lookup or owner's manual before ordering.

• Compatible with GLA250 (2.0L), GLA200 (1.6L), CLA250, B250 and related models.
• Works with certain AMG and electric Drive variants listed in the fitment notes.

How often should I replace the cabin air filter?

Replacement intervals depend on driving conditions: urban, dusty or high‑pollution environments demand more frequent changes. A general guideline is to inspect the filter annually or every 12,000–15,000 miles and replace when visibly dirty or when airflow and odor control decline.

• Inspect at every scheduled service or at least once a year.
• Replace sooner if you notice reduced HVAC airflow or persistent odors.
• Driving in dusty or heavy-traffic areas typically shortens service life.

Is installation difficult and will it affect my car’s HVAC system?

Installation is a simple, low‑effort maintenance task on most compatible Mercedes models and typically requires no special tools. The PUREFLOW filter is designed to match factory dimensions and airflow so it won’t impede the ventilation system when installed correctly.

• Direct-fit design aligns with OEM housing and seals.
• Usually a quick swap behind the glovebox or under the cowl, depending on model.
• No reprogramming or system changes are required.
