Abstract: The single-hand-operable micro water purifier of the present application relates to a micro water filter, especially a micro water purifier which can filter water by means of pressuring. It consists of a micro filter device and a raw water pressurizing device. The micro filter device consists of a filter cylinder body, a filter water inlet, and a filter water outlet and a filter material assembly located in the filter cylinder body. The raw water pressurizing device consists of a pressurizing device water inlet, a pressurizing device main body, and a pressurizing device water outlet. The present application can promote the raw water to enter the filter device for performing the filtration to obtain the clean water, by using a single hand to operate, which not only brings convenience to the user, but also saves labor and improves the use efficiency.
