Problems solved by technology

The filament non-woven filter cloth filter element has a filtering effect on dust in the air, but it is difficult to remove industrial waste gas, bacteria, smoke and other harmful gases and various odors, so the filtering effect is not good.

In addition, the existing air conditioner filter not only replaces the filter element, but also replaces the frame body on which the filter element is installed. Although the price is relatively cheap, it is also relatively wasteful.
