疫情持續之下，多用途消毒噴劑更多疫情已經成為大多數市民的日常必須用品。市面上消毒噴劑款式眾多，消委會就公布了15款多用途殺菌消毒噴劑的測試結果，發現有8成短時間內殺滅細菌病毒的效能有限，反而適當使用稀釋漂白水及消毒酒精，更經濟實惠。
消委會早前測試了市面15款多用途殺菌消毒噴劑，發現樣本的殺菌及消除病毒感染力表現參差。當中8成樣本，包括9款說明殺菌率及殺病毒率達到99.9%或以上的樣本，表現都比75%消毒酒精或/及含500ppm有效氯的稀釋漂白水溶液(即相等於以1:99比例稀釋含5.25%次氯酸鈉漂白水所得的溶液)差。
消委會測試中有8款樣本可同時有效殺滅大腸桿菌K12和金黃葡萄球菌，殺菌率超過99.999%：
消委會以相同試驗方法和條件，測試按世界衛生組織建議配方製備的75%消毒酒精及含500ppm有效氯的稀釋漂白水溶液（即相等於以1:99比例稀釋含5.25%次氯酸鈉漂白水所得的溶液）。結果顯示，這兩種常用的消毒溶液，對付2種試驗細菌同樣達到99.999%殺菌率，抑制腺病毒感染力效能亦分別達到87.98%及99.83%。
消毒噴劑的售價普遍較高，每瓶／每套售價由$88至$798，若以每毫升計算，則介乎約$0.27至$0.99，相比消委會於去年4月出版的消毒酒精測試報告，消毒酒精每毫升的價格只是介乎$0.04至$0.5，平均售價較便宜。消委會就指，消毒酒精和稀釋漂白水如分別用於消毒雙手和一般環境消毒用途，是較價廉物美的選擇。
