Hand dryers have problems with microbial growth, dirty drainage holes, incomplete drying, and excessive microorganisms, which affect the hygienic effect.
Problem 1: Microbial and mosquito breeding
The water trays of some hand dryers have not been cleaned in time, and the accumulated water and sanitary dead corners are easy to breed microorganisms and mosquitoes, affecting the use effect.
Problem 2: Dirty drainage holes
The small holes at the bottom of the hand dryer are only about 10mm in diameter, but the depth is 50-80mm. It is not easy to observe the internal dirtiness and is often overlooked. But just wipe it lightly with a cotton swab to find the dirt inside.
Problem 3: Incomplete hand drying
Many people do not ensure that their hands are completely dried before using the hand dryer. Afterwards, they may take the following inappropriate measures: wipe their hands on clothes and disinfect them, spray disinfectant alcohol or disinfectant directly, or use the hand dryer again to dry them. These behaviors may affect the hygienic effect.
Question 4: Hand dryers have excessive microorganisms
Due to different hygiene standards for hand dryers, many hand dryers may have excessive microbial content. If they are only cleaned but not disinfected, and the wipes used do not meet the requirements for food contact surfaces, the risk of cross-contamination may increase.
