During the dust collection process when the filter reaches the dust holding capacity, a low-efficiency filter is prone to first increase and then decrease in efficiency. A low-efficiency Teflon air filtration membrane filter collects large amounts of dust. The filter material is sparse, and dust particles can easily penetrate the filter material and peel off due to increased resistance, causing secondary pollution.
During use, the efficiency of a high-efficiency filter will generally increase as dust accumulation increases.
It is a manufacturer of polytetrafluoroethylene (ptfe) membrane environmentally friendly materials that specializes in R&D, production and sales.
It has advanced ptfe film production lines, lamination and composite production lines, which are at the domestic advanced level.
If necessary, you can try the products in the store. I have used them before and the quality is very good.
