String Wound Sediment Filter ----Food grade 100% Polypropylene material, Lead and BPA-Free. Non-toxic, odorless, no leaching or secondary pollution.
Outstanding Performance:
The string wound filter has a deep graded honeycomb structure, dense near the inside core and more open and sparse near the outside edge, forming an effective depth filtration filter, catching larger particulates first and then smaller near the center core, effectively increasing the dirt holding capacity of the filter.
Significant Difference between String Wound Filter with Melt-Blown Filter:
Flow Rate: String Wound Filter > Melt-Blown Filter
Dirty-holding Capacity: String Wound Filter > Melt-Blown Filter
Service Life: String Wound Filter > Melt-Blown Filter
