Ultrasoinc press-point composite filter material is compounded of polypropylene super-fine nonwovens and polyester nonwovens by ultrasoinc press-poine. Compared with other products at the condition of reaching the same efficiency, the resistance of this filter material decreases by 20 percent. Simultaneously, it owns the advantage of great dust capacity, high intensity, and extending the life-span of filter, so that this product is an ideal filter material used in air filters.

Filter efficiency : F5-H10 (80%-99.95)
