在一些更換頻率較高的行業，通常建議使用一次性用品，這樣不但可以避免交叉感染，更可以大大節約更換成本，比如醫療行業、實驗室、食品加工行業等對衛生要求比較高的行業。

In some industries with high replacement frequency, it is usually recommended to use disposable products, which can not only avoid cross infection, but also greatly save replacement costs, such as medical industry, laboratory, food processing industry and other industries with high health requirements.
