PET (Polyester) Pleated Filter Cartridges are engineered to deliver exceptionally high flow rates with minimal pressure drop. The unique pleated design dramatically increases the filtration surface area compared to standard spun or wound filters. This expanded area allows the cartridge to capture and hold significantly more sediment, dirt, scale, and rust before requiring maintenance.

Manufactured from highly durable, non-woven polyester (PET) media, these filters are highly resistant to chemicals and bacterial attack. One of their most popular advantages is that they are often washable and reusable; a simple rinse can clear the pleats of heavy debris, extending the lifespan of the cartridge and making it a highly cost-effective solution for whole-house, commercial, and industrial water treatment applications.
