description The invention belongs to the field of water purifiers, and discloses a method and a device for detecting air leakage of an ultrafilter. The method comprises the following steps: inflating the liquid inlet end of an ultrafilter; stopping inflation when the air pressure reaches an inflation set value; pressuring the ultrafilter, starting to time, and detecting the pressure at the liquid inlet end of the ultrafilter when the pressurizing time reaches the set time; outputting a rejected detection signal if the pressure at the liquid inlet end of the ultrafilter is detected to be equal to or lower than the air leakage set value; outputting a qualified detection signal when the pressure at the liquid inlet end of the ultrafilter is detected to be higher than the air leakage set value; and deflating the air inlet end of the ultrafilter. According to the method and the device disclosed by the invention, the ultrafilter is inflated and pressurized, the pressure at the liquid inlet end of the ultrafilter is detected wh
