The present application discloses a micro electrostatic purification device for resisting high humidity, including an ionization module, a micro electrostatic filter and a power supply module, the two ends of the insulating dielectric material in the cartridge carbon electrode length direction are installed inward respectively into the first electrode strip and the second electrode strip, and finally closed with a sealant, and the connection of the individual wire is sealed by filling sealant, to achieve the complete closure of the cartridge. The connection between the power module and the electrode strip, and the connection between the electrode contact piece and the external power supply are all completely sealed through the setting of the structure. And a current limitation protection circuit is provided to monitor the working current in real time and carry out current limitation protection when the instantaneous change of the working current exceeds the threshold.
