Inspired by: The toilet is one of the most commonly used spaces in home. The quality of the bathroom and toilet environment directly affects the quality of life. The data shows that some users will stay in the toilet for longer time, using it as toilets, and for bathing, reading, etc. The air in the toilet hardly circulates, causing moisture and bacterial growth and therefore generating odor, which affects the health and mood of the user.
