Medical mask hack suggested for refrigerator hygiene

A household tip suggests using a medical mask to help deodorize and absorb moisture in refrigerators. By cutting one end of a mask, filling it with dry tea (such as green or black tea), and tying it shut, the mask can act as a filter to reduce odors and humidity.

According to Associate Professor Dr. Nguyễn Duy Thịnh, maintaining a clean and dry refrigerator is essential for food safety. High humidity and mixed food odors can encourage the growth of bacteria and mold, which may lead to digestive issues, particularly in children and the elderly. Replacing the tea-filled mask approximately once a month is recommended to maintain effectiveness.
