The difference between a nanofiber screen and ordinary mesh

Ordinary insect mesh is made of woven threads and only stops insects. A nanofiber screen, however, contains a membrane of fibres much finer than a hair; it lets air through while also holding back most dust, pollen and soot.

The difference between a nanofiber screen and ordinary mesh

Short answer

The difference is in the pores. In woven mesh, a pore is the gap between threads; in nanofiber, it is a web formed by countless fine fibres.

Ordinary mesh

Made by weaving polyester or fibreglass threads.
Its holes are smaller than a mosquito but far larger than dust.
Air flows very freely.

Nanofiber screen

A layered structure with a nanofiber membrane in the middle.
Holds back dust, pollen, soot and tiny insects.
Lets air through; on very still days the flow slows a little.

Which one suits whom?

If you only have an insect problem, ordinary mesh is enough. If dust, pollen or soot also bother you, a window filter is the right choice.
