HEPA air purifiers perform the air purification process via different layers of filters which trap different types of pollutants like dust, smoke, pollen, and bacteria.

However, the bacteria are only trapped but not killed, and there is still a potential for secondary pollution. The performance of the filters will degrade when more and more pollutants are trapped.

Thus, the complete replacement of the filter is the only way to re-gain the high purification efficiency. There are incremental costs associated with the HEPA filter, as well as the fact that it creates secondary pollution during the disposal of the aged filters.

On the contrary, our device with the patented HIRD technology effectively traps the pollutants as well as kills the bacteria through the strong electrostatic field. The easy cleaning feature of the collector tray with water helps to protect our environment and avoid secondary pollution.
