On December 6th, Xiaomi's ecosystem partner Zhimi expanded its product range beyond air purifiers and introduced a new outdoor solution: the Zhimi Light Breathing Mask. Launched at 10 AM, this innovative mask is available in a three-pack for just 39 yuan, making it an affordable and practical choice for daily use.
The Zhimi Light Breathing Mask meets the KN95 protection standard, offering superior breathability compared to traditional masks. Its low inspiratory resistance—only 100Pa—ensures comfortable breathing even during physical activities, without the discomfort of tightness or the need for frequent replacements. Unlike conventional masks that often cause irritation due to rigid materials, this one uses TPU elastic film and eco-friendly polyurethane cotton, similar to the Japanese Pitta Star mask. This material adapts to your face over time, becoming more comfortable with each use.
One of the key features of the Zhimi mask is its 3D dome frame and high-ventilation filter. This design allows for nearly 100% airflow through the filter, significantly reducing resistance. The mask also provides a pre-breathing space of about 200cm³, giving users a refreshing and unobstructed breathing experience—even when wearing it during exercise.
Inside, the mask contains five layers of high-efficiency filtration. The first layer filters out large particles like dust and pollen, while the double-layer melt-blown HEPA fiber effectively captures PM2.5, bacteria, and other harmful substances. With a filtration efficiency of over 97%, it meets the latest GB/T 32610-2016 standards and offers reliable protection against pollutants such as car exhaust and fine particulate matter.
The mask also features an improved breathing valve with a 40mm outer diameter and a 0.3mm ultra-thin silicone valve. This ensures smooth airflow, minimal exhalation resistance (only 45Pa), and keeps the face dry and comfortable throughout the day.
To address common issues with airtightness, the Zhimi mask includes an adjustable ear strap with three gear positions. This allows for a secure fit, whether you wear glasses or have a smaller or larger face shape. The flexible design ensures a snug fit without causing pressure or leakage.
With a recommended usage time of 10 hours, one mask can last up to a week if worn for two hours per day. It’s a smart, cost-effective, and user-friendly option for those looking for reliable protection in polluted environments.
