A mask worn over the nostrils to protect against the air you breathe (particulate matter, pollen, car exhaust, etc.).
"Hanji microfiber filter" (Hanji + microfiber + "cotton") is made of 600 strands of natural filter, enabling you to breathe comfortably with smooth inhalation and exhalation - similar to normal breathing.
70% of fine dust PM 2.5 blocked!
The circular wings in the center of the body are designed to block air from entering the nasal passages during inhalation, allowing you to breathe only through the central filter.
1. The silicone can be washed in cloudy water and reused, making it practical and economical. 2. Reusable with natural paper filter replacement. Replace the filter once a day (every 6 hours) or when breathing is not comfortable.
