Abstract: Foot massaging is a traditional health manner in China and foot massager makes this manner more convenient. However, there are some problems such as microbial growth and cross-infection due to the warm water, mixed use and so on. Many foot massagers with ozone generator appear in the market now and promote the ability to cure athletes. The theory of cure athletes is to eliminating the microbiology that causing athlete's foot. This paper study the eliminating microbiology performance by adding E.coli, S.aureus, C.albicans and T.rubrum into Foot massager. The results show the highest eliminating rate are 50.00% for bacteria and 62.00% for fungi in the test duration of 30min. Even if the test duration extend to 60min, the highest eliminating rate are only 50.00% for bacteria and 62.00% for fungi. This shows practical effect of eliminating microbiology is false promotion. In order to put an end to such problems and promote the industry development, standards about the eliminating microbiology performance should be drafted and strengthen market supervision at the same time.
