Xiaomi YU7 3-Stage Air Purification System Explained
Q: What’s special about the 3-stage air purification system in the Xiaomi YU7?
A: The Xiaomi YU7 features a 3-stage air purification system comprising 2 standard air conditioning filters, 2 large thin-type primary filters, and 2 HEPA filters. The primary filters intercept larger particles, while the HEPA filters efficiently capture smaller particles. The primary filters also protect the HEPA filters, extending their lifespan.
The HEPA filters in the YU7 offer exceptional filtration performance. For comparison, N95 masks filter 95% of 0.3-micron particles, whereas the YU7’s HEPA filters achieve 99.95% efficiency for the same particle size, surpassing N95 masks and acting like a “super-sized high-efficiency mask” for the vehicle. This is particularly beneficial for allergy sufferers, significantly improving cabin air quality and providing peace of mind for sensitive individuals and families with children.
Notably, the Xiaomi YU7 has recently earned the “Five-Star Healthy Vehicle” award, achieving the highest ratings in all three evaluation dimensions: fresh air, health protection, and green mobility. The top ratings in fresh air and health protection indicate excellent cabin material quality, such as low levels of harmful volatile compounds like formaldehyde and low allergen risk on frequently touched surfaces like seats, along with an efficient air conditioning filtration system. In the green mobility dimension, the rating is determined by testing the vehicle’s range achievement rate under different temperatures and speeds, where the YU7 also received the highest five-star evaluation. Previously, the Xiaomi SU7 also achieved the highest ratings in all three health evaluations.
