More About MESP® Technology

MESP® Technology

MESP® stands for Micro-electrostatic Precipitator, a new generation indoor air clean technology, which is a high-efficiency air purification and sterilization solution through insulated filter with strong electric field.

The Strength of MESP

Kill Viruses & Bacteria

Efficiently Eliminate PM2.5

Washable Filter


High Usability


Kill Viruses & Bacteria

MESP® technology is able to high effienctly kill viruses and bacteria with unique strong electric field. The sterilization rate for white staphylococcus is more than 99.9%. The sterilization rate for viruses (refer to the test reports of H1N1 and Sars-Cov-2) is 99.99%.
Remark: ① the test report provided by SGS and Shanghai Institute of Preventive Medicine. ② the test report from Innovative Bioanalysis in California, US. SARS-CoV-2 is the virus that causes COVID-19.

High Efficiency

Differing from traditional media filters, the pressure drop is low with MESP filters because there is no need to force air through a matrix of small air passages. The physics makes its higher efficiency. Further more, MESP made Air Conditioning Sterilizing Purifiers (In-Duct Air Purifiers) can work with HVAC system to get extremely clean indoor air quality in short time.
Remark: Air Purifiers can be installed with air handling units, fan coil units, air duct and ventilation etc.

Washable Filter

The unique nano PP made filter is permanently washable and designed for more than 10 years lifespan. The total running cost should be much lower than traditional media-filter products.
Remark: ① Caculated based on the annual average dust removal capacity and the final purification capacity not lower than 80% of the initial one.


The MESP filter works with about one micro-ampere (one millionth of one ampere) of current at 6-10 kilovolts, which always prevent from electric shock. No ozone. No any harmful byproducts.
Remark: ① According to the test reports from National Air Conditioning Equipment Quality Supervision and Inspection Center (or Shanghai General Station of Environmental Protection Product Quality Supervision and Inspection.), it indicates that the measured ozone concentration has not increased.

High Usability

No worry about extreme change of humidity (up to 95%) and temperature (-15℃ to 48℃), our products will work properly all the time.

Energy Saving

Low air pressure drop makes our products working with low power supply. Compared with the use of HEPA filters, the energy consumption of fans using MESP purifiers is only 1/6 to 1/7.
