How often does the HEPA High-Efficiency Air Purification System filter need to be replaced?
The Xiaomi YU7 offers an optional HEPA High-Efficiency Air Purification System (complimentary for all trims if ordered before 24:00 on July 31). Under normal driving conditions, we recommend replacing the filter once a year or every 20,000 kilometers driven. For specific assessments, please visit the dealership.
Beyond the standard air conditioning filter, the HEPA High-Efficiency Air Purification System adds two pre-filter filters and two HEPA filters. Among them, the HEPA filter features a nano-microporous protective layer, offering the strongest filtration effect. Tests show that the HEPA filter achieves a filtration efficiency of >99.95% for particles sized 0.05~0.3μm, and >99.99% efficiency against bacteria, fungi, and viruses such as Staphylococcus aureus, Influenza A virus, and H1N1, effectively blocking external pollutant particles from entering the cabin. Additionally, the Xiaomi YU7 provides a deep air purification function, achieving full-vehicle rapid air exchange in as fast as 35 seconds, always providing healthy and fresh air for the cabin.
