String Wound Vs Melt Blown Filter Cartridges

There is a lot of confusion and different expert opinions when it comes to choosing or selecting a filter – and the widely asked question is “string wound or melt blown?” Conventionally if we talk about string wound and melt blown filter cartridges, melt blown variant gets a plus one as it has a fixed pore structure. Fixed pore structure means that when the filter faces differential fluids, the polypropylene fibers do not sperate – if they sperate the trapped contaminant particles might flow into the filtrate. However today, with the use of Advanced technology, high quality string wound cartridges are engineered, and this differentiation is rendered redundant.
