MESP™ stands for Micro-electrostatic Precipitator, which is a new generation air purification technology. It can high-efficiently capture airborne particles and remove PM2.5, virus, bacteria, pollen, allergen, and other particulate pollutants.
MESP technology is upgraded from ESP (Electrostatic Precipitator). Comparing to ESP, MESP has 10 times of clogging capacity and greatly solves the problem of ozone generation, arc and spark.
The particle collection filter is an innovative dielectric with an intense electrical field. It describes the mechanism by which the MESP filter is able to remove even the tiniest particles without the use of a high-pressure-drop fiber matrix. Airborne particles are first given an electrical charge, then passed into a honeycomb of 2-4mm diameter hollow polymer flutes. Encased between rows of flutes are thin electrode sheets, which generate intense electrical fields. The polymer flute material is dielectric, which prevents current from 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.
The unique volt-ampere characteristic curve of AirQuality MESP technology makes the current get very small while the voltage increases again. Therefore, high voltage and low current have no risk of electric shock, and there is no need to worry about the harm of ozone. The unique nano PP insulation coating technology of micro static electricity can effectively avoid the potential dangers of electrode damage and electric shock, which are traditional ESP products' weaknesses.
The unique nano PP made filter is washable and its overall lifespan could exceed 10 years with small effect attenuation. The total running cost should be much lower than traditional media filter products.
The Diagram of MESP Working Principles
MESP uses negative ionization technology to generate corona and release negative ions through a voltage of -10.2KV. The negative ions collide with air molecules to generate more negative ions and form an avalanche effect.
▼
After being far away from the corona zone, the negative ions will be attracted by the surrounding air, so that the gas molecules will be negatively charged and move towards the MESP positive plate under the action of a strong electric field.
▼
The fine particles will block the negatively charged air molecules from flying and stick them together. The fine particles continue to absorb negatively charged molecules until they are saturated. The fine particles thus carry enough negative charges.
▼
The negatively charged fine particles move to the positive plate under the action of the dense MESP matrix electric field, and are firmly attracted by it.
