OIFILLIO Cabin Air Filter for BMW X5 X6 X7 & 5/7 Series (2-Pack) — Activated Carbon, OE Fit

OIFILLIO cabin air filters are a two-piece replacement set with coconut-shell activated carbon built to fit multiple BMW X5, X6, X7 and 5/7 Series model years, restoring cleaner, odor-reduced airflow inside the cabin.

This replacement pair is designed to match OE fitment (cross-references include 64119366401 and 64115a1bdb6) and to trap particles and odors that standard paper filters miss. Made with activated carbon media, the filters adsorb smells from traffic and city pollution while capturing dust, pollen, and other airborne debris that can circulate through your vehicle’s HVAC system. The set is offered for a broad range of BMW model years—check the compatibility list below to confirm fit before ordering.

Which BMW models and years does this filter set fit?

The OIFILLIO cabin air filter 2-pack covers many X5, X6, X7 and select 5/7 Series model years from 2016 through 2025. Fitment includes both naturally aspirated and hybrid variants as listed in the product compatibility. Always verify your current OE part number or cross-reference to ensure correct selection.

• Compatible: BMW X5, X6, X7 (2019–2025) and selected 8 Series (2020–2025)

How does the activated carbon media improve cabin air?

Activated carbon in these filters adsorbs volatile organic compounds (VOCs) and common odors—traffic exhaust, fuel vapors, and mildew—reducing unpleasant smells that plain particle filters can’t capture. The carbon layer works alongside a particulate media to provide dual-action protection without impeding airflow when installed correctly. This combination helps maintain a fresher-feeling cabin for drivers and passengers.

• Coconut-shell activated carbon targets odors and VOCs
• Multi-layer media captures pollen, dust, and soot
• Designed to balance filtration with HVAC airflow efficiency

Is installation difficult and how long does it take?

Installation is typically straightforward and can be completed in minutes using basic tools or no tools at all, depending on the BMW model. The filters follow OE dimensions for a direct fit into the factory housing; replacing them as a matched pair helps ensure even performance. If you encounter fit issues, OIFILLIO provides customer support to guide you through the process.

• Direct OE-style fit—no trimming required when matched to correct model
• Most replacements complete in under 15 minutes per vehicle
• Packaging includes two filters for front and/or dual housing setups

How often should these cabin filters be replaced?

Replacement frequency depends on driving conditions, but a general guideline is every 12,000–18,000 miles or once a year under normal use. If you regularly drive in heavy traffic, dusty environments, or areas with high pollen counts, inspect and replace the filters more frequently. Monitoring HVAC performance and odor levels will also indicate when a swap is needed.

• Typical interval: 12,000–18,000 miles or annually
• Inspect sooner in dusty or high-pollen regions
• Swap both filters when dual housings are used for balanced filtration

This OIFILLIO cabin air filter set is intended for BMW owners who want a cost-effective, OE-compatible replacement that adds an activated carbon layer to help reduce odors and common airborne contaminants. It suits DIY mechanics and professional installers who need reliable fitment across multiple BMW X, 5, and 7 Series models. If you prioritize fresher cabin air without altering HVAC performance, this two-piece activated carbon set offers a practical upgrade to standard paper-only filters.
