Product Description


Hongtek PET Series Polyester Pleated Filter Cartridges are constructed of pleated Polyester(PET) filter media, with central core and high-grade end cap. Polyester pleated cartridges have low pressure drop and high flow capacity. PET pleated cartridges are produced using 100% synthetic fibers, which are free of binders or adhesives, exhibiting highly effective retention efficiency. What’s more, they are washable and reusable commodiously.

Polyester pleated filter cartridges also called water replacement filters. The pleated design increases surface area and extends service life, making PET pleated cartridges to be one of the most economic options in water treatment.
