1.Washing-resistance
HHC/G filters can satisfy customers who hope that filters cab be used again after being washed. Some users of HHC/G filters wash filters for more than 10 times to extend the service life of filters to 2 year.
2.Low resistance
The filters adopt special filtering media and reasonable structure to lower the resistance of the falters to the lowest level.
3.Stable performance
The filber filtering media in HHC/G bag filters do not contain static electricity so there is no element in the filtering data that is temporarily improved due to static electricity. Filtering effciency maintains initial function after washing if the filtering medias are not broken.
HHC/G bag filters are mainly used in central air-conditioning and ventilation systems. They can be used in the first-stage filtering in air-conditioning systems to protect the filters of the next stage and  the system as a whole. In csses where requirement on air-purifying level is not high, such as office building, supermarket,power distribution room and general industrial and public areas that need central ventilation, air can be delivered to customers dirrectly after filtering of HHC/G filters.
