Reusable mask

thingiverse

Filter out regular cotton pads to prevent irritation. Grind off rough edges that may come into contact with sensitive skin. When installing a new filter, turn it counterclockwise for easy installation. To release the old filter, simply turn it clockwise. For improved wearing comfort, apply moisture-resistant thick tape along the edges to create a smooth seal. Replace the cotton filter frequently to maintain optimal performance and wash the mask regularly with warm water and mild soap to keep it clean and hygienic.
