SPEARHEAD cabin air filter Breathe Easy BE-934 for select Mercedes-Benz (2008–2021) — activated carbon, up to 15,000 mi life

The SPEARHEAD Breathe Easy BE-934 cabin air filter is a multi-layer replacement filter with coconut shell activated carbon that reduces odors and captures fine particles for up to 15,000 miles.

If you drive a compatible Mercedes-Benz C-Class, E-Class, CLS, GLK, AMG GT, SL-Class or SLS AMG from select years, the BE-934 is built to be a direct-fit replacement for the factory cabin filter. SPEARHEAD designed this filter with thicker electrostatic media and real activated carbon to trap dust, pollen, road particles and many airborne odors before they enter the passenger compartment. The package includes an installation guide so many owners can replace the filter themselves and avoid service costs.

How does this filter improve in-cabin air compared with a standard filter?

The BE-934 uses denser, electrostatically charged pleated media that actively attracts and holds smaller particles that ordinary filters may miss. A layer of genuine coconut shell activated carbon further adsorbs gases and odors, reducing smells from traffic and exhaust.

• 2x heavier electrostatic media for better particle capture
• Real coconut shell activated carbon to reduce odors and VOCs
• Multiple pleated layers to extend service life and efficiency

What vehicles and model years does this SPEARHEAD cabin filter fit?

BE-934 is manufactured as a replacement for a range of Mercedes-Benz models from 2008 through 2021. Always verify fitment with the vehicle lookup tool before ordering to ensure proper compatibility with your specific year and trim.

• Fits many C-Class, CLS and E-Class models from 2008–2018 and various AMG versions
• Compatible with GLK250/GLK350, AMG GT series, SL and SLS AMG model ranges listed in the fitment details

How long will the BE-934 last and when should I replace it?

SPEARHEAD engineers the Breathe Easy filter for extended service life—up to about 15,000 miles under typical driving—about 25% longer than many standard cabin filters rated at roughly 12,000 miles. Replace intervals depend on local conditions: dusty roads, heavy traffic, or frequent urban driving may require earlier changes.

• Estimated service life: up to 15,000 miles under average use
• Check sooner if you notice reduced airflow, odors, or increased cabin dust
• Installation guide included to simplify DIY replacement

Is it easy to install this filter myself and what comes with the order?

Yes—many owners perform the swap themselves. Each BE-934 ships with a straightforward installation manual. If you prefer, a quick visit to a shop will complete the replacement in a few minutes for most compatible models.

• Included: step-by-step installation manual with diagrams
• Simple hand tools typically required; no special equipment
• DIY kit saves money compared with dealer service visits

The SPEARHEAD Breathe Easy BE-934 is suited to vehicle owners who prefer a higher-capacity, activated-carbon cabin filter and those who want the option to install the filter themselves to reduce maintenance costs.
