High Efficiency Particulate Air Filter:
The sealing property is far more than the paper border with using the plastic margin. To ensure the health and non-pollution, we take the environmental friendly imported sealant, no color and no odor. The filter element that we use is 3M HEPA, meeting the European standard- H13, and the PM2.5 removal rate can be up to 99.97%, this large dust holding capacity helps to save the total cost.
