Filter cartridge of air purifier

The utility model discloses a filter cartridge of an air purifier. The filter cartridge is made of a filter material with the breaking strength of 220N/5cm-1000N/5cm, the 50N elongation of 1%-2.5% and the film covering fastness of 0.04 Mpa-0. 15MPa; according to the utility model, the pressurized water can be used for flushing, and dust after scaling can be crushed and taken away by the water, so that particles on the surface of a filter material can be effectively cleaned, the filtering effect of the filter cartridge can be recovered, the regeneration use can be realized, and the service life of the filter cartridge can be prolonged. 本实用新型公开了一种空气净化器的滤筒，由断裂强力为220N/5cm-1000N/5cm，50N伸长率为1%-2.5%，覆膜牢度为0.04Mpa-0.15MPa的滤料制成；使得本实用新型可以通过加压水冲洗，利用加压水将"结垢后"的粉尘冲碎，并被水带走，有效地清洗掉滤料表面的颗粒物，使滤筒恢复过滤效果，实现再生使用，从而增加滤筒寿命。
