Efficient filter cotton: this is a more dense mesh of the surface wind, at the same time it also adds a layer of grid nets to finalize the design, this kind of structure to keep filter material of high filtration efficiency and the amount of dust, still can prolong the service life of filter material, in the use of 600 g and 560 g, besides can ensure good air quality, due to the filter material itself relatively resistance.
It also has a special structure, which takes advantage of the multilayer encryption technology, namely the pure air direction of fiber density increased gradually, high filtration efficiency, according to the dust size, is blocked at the level of the different density and more effective to hold more dust. There are three properties of filter material: surface viscosity, total viscosity and dry.

Such products can also be used with the outer frame, which can be used as a plate filter. It is a high performance thermal fusion process made of anti-fracture organic synthetic fiber. In viscous processing, filter material is completely after soak glue for adhesive completely osmotic medium and make the dust particles cannot pass, make comprehensive filtering air flow evenly spread, the laminar state formation, the optimum effect of spraying.
