Filter FreciousSmart

Overview
MANN+HUMMEL multi-stage cabin air filter systems are designed for passenger vehicles to reduce occupants' exposure to airborne contamination. Combining pre-filtration, long-life gas adsorption and HEPA stages, available systems include sensor modules for continuous monitoring and automatic control of cabin air quality. The result is targeted filtration of ultrafine particles and optimized energy usage in ventilation systems.

Product benefits

• Filtration of ultrafine particles with HEPA grade elements (<0.1 µm)
