Premium Guard PUREFLOW Cabin Air Filter for Mercedes‑Benz 2.0L (PC99555X) — Activated Carbon, OE Fit for GLB/GLA/CLA 2020–2026

The PUREFLOW PC99555X cabin air filter is a four-layer, activated-carbon replacement designed to trap dust, pollen and common road odors in select 2020–2026 Mercedes‑Benz GLB, GLA and CLA models.

This replacement filter was engineered to match OE fit and airflow needs for several Mercedes‑Benz 2.0L models, offering multi-stage filtration that helps protect your HVAC system and keeps the vehicle cabin feeling fresher. It installs in the factory housing, uses an integrated activated carbon layer to help manage odors, and captures fine particles before they circulate through vents and onto interior surfaces.

Which Mercedes models does this filter fit?

The PUREFLOW PC99555X fits a range of Mercedes‑Benz compact models from 2020 through 2026 that use the specified 2.0L platform. Confirm fitment by comparing the part number and dimensions to your vehicle’s existing cabin filter or owner’s manual.

• Compatible models: GLB250, GLA250, CLA250, CLA35 AMG, GLA35 AMG, GLB35 AMG, CLA45 AMG S (2020–2026)
• Also compatible with various A, EQA and EQB derivatives listed in the product features
• OE-style shape for direct, tool-free replacement in most installations

How does the multi-layer design improve cabin air?

PUREFLOW's four-layer media uses progressively finer layers to capture larger debris first, then trap smaller particulates such as dust and pollen. The included activated carbon layer adsorbs many common airborne odors and volatile compounds, reducing noticeable smells entering through outside air intake.

• Layered media for staged filtration and extended service life
• Activated carbon reduces traffic and exhaust odors
• Reduces particulate load on the HVAC system for consistent airflow

What are the benefits of replacing the cabin filter on schedule?

Changing the cabin filter at recommended intervals helps maintain clean airflow, reduces dust settling on interior surfaces, and supports the HVAC blower and heat-exchange performance. A fresh filter can also minimize unpleasant outside odors and reduce the amount of debris that would otherwise reach sensors or evaporator surfaces.

• Preserves HVAC efficiency and consistent vent airflow
• Less interior dust and fewer odors inside the cabin
• Simple filter swap — typically located behind glovebox or under cowl depending on model

How easy is installation and what should you check after replacing it?

Installation is straightforward for most owners and technicians; the PUREFLOW filter is shaped for direct replacement in the factory housing. After fitting, check vent airflow and ensure no gaps or misalignment; a correctly seated filter prevents bypass and ensures filtration effectiveness.

• Expect a direct fit in factory filter housing—no trimming required
• Inspect seals and orientation arrows when installing to avoid bypass air
• Verify normal cabin airflow and absence of rattles after reinstalling panels
