The nasal cavity filter is an invisible air purification device. The filter is pushed into the nasal cavity. Through the built-in filter, the unclean particulate matter is filtered out to achieve the effect of filtering air. People with this filter can always inhale fresh and clean gas. The product is small and easy to carry, commonly known as "invisible mask", which does not affect face-to-face communication with others when used. At the same time, it solves the characteristics of breathing difficulties when wearing a mask and moisture when used for a long time.
