About us
Kefilbao Filter Technology (Suzhou) Co., Ltd. is a high-tech company specializing in bag filters and folding filter elements, integrating product research and development, production, and sales.

The hydrophilic PVDF membrane filter cartridges are highly retentive, low protein-binding. The PVDF membrane filter utilizes single layer hydrophilic PVDF membrane. It offers broad chemical compatibility, high flow rate and low extractables. No adhesives, binders, or surfactants are used during the manufacturing process resulting in superior downstream cleanliness. All filters are rinsed with high-purity water to reduce extractables and downtime.
