Upgrade your vehicle’s air quality with the Bosch External Air Conditioning Filter, engineered for high-efficiency filtration and long-lasting performance. As a critical first line of defense, this external cabin filter captures contaminants before they enter your HVAC system, ensuring cleaner, healthier air for every drive.

Built with FILTER⁺pro multi-layer technology, the Bosch external AC filter features a high-performance structure: an ultrafine microfiber layer traps fine dust and PM2.5 particles (99.97% filtration efficiency), an activated carbon layer absorbs harmful gases, odors, and VOCs, and an antimicrobial layer inhibits bacteria, mold, and allergens. This robust design delivers comprehensive protection against pollen, exhaust fumes, smoke, and airborne irritants, ideal for urban commuting, highway travel, and allergy-prone environments.

Crafted with German-engineered quality, the filter uses premium, moisture-resistant media and a precision-fit polyurethane sealing lip to prevent unfiltered air bypass. Its large embossed surface area ensures high particle holding capacity with low airflow resistance, maintaining optimal AC performance without reducing cooling efficiency. Compatible with a wide range of vehicles, including Tesla Model Y, Mercedes-Benz, and more, it offers OEM-grade reliability and easy, tool-free installation.

Regular replacement (every 12 months or 10,000 miles) prevents clogged airflow, reduced AC output, and poor air quality. The Bosch External Air Conditioning Filter not only safeguards passenger health but also protects your HVAC system from dirt and debris, extending component life.

Invest in Bosch’s trusted filtration innovation—where advanced technology meets durable construction. Breathe cleaner air, enjoy consistent AC performance, and drive with confidence knowing your cabin is protected by the best.
