MESP stands for Micro-electrostatic Precipitator, which is a new generation air purification technology.  It is highly efficient at removing airborne particles like PM2.5, fungus, dust, pollen, soot, smoke and powerfully deactivates viruses and bacteria.

MESP technology is an upgrade from ESP (Electrostatic Precipitator) technology.  Compared to ESP, MESP not only has 10 times the clogging capacity, but also solves the problem of ozone generation, arc, and spark.

Micro Electrostatic Precipitator is a new generation air purification technology. Intense dielectric field describes the mechanism by which the MESP filter can remove even the tiniest particles without the use of a high-pressure-drop fibre matrix filter. Airborne particles are first given an electrical charge, then passed through a honeycomb of hollow polymer flutes, 2-4 mm in diameter.

Encased between rows of flutes are thin electrode sheets, which generate intense electrical fields. The polymer flute material is dielectric, which prevents current flowing between electrodes but does not inhibit creation of an intense field within the flutes. Charged particles are pulled to the walls of the flutes, where they stick.
