Filter Technologies in IV Infusion

Wishing everyone a fantastic start to the week! We are sharing some information on medical filter technologies. In IV infusion, all kinds of filter technologies ensure that the medications and fluids administered to patients are safe, pure, and effective. Various filtration technologies remove particulate matter, microorganisms, endotoxins, air, and other contaminants from IV solutions.


IV infusion filters are classified by the nature or size of the particle they remove:

  • Sterile Filter

  • Bacterial Filter

  • Air Filter (Vent Filter)

  • Hydrophilic Filter

  • and more Or

  • Macrofiltration

  • Microfiltration

  • Ultrafiltration

  • Nanofiltration

  • Reverse Osmosis

Amongst the above filtration technologies, semi-permeable membranes come in various shapes, and surface areas are commonly adopted and particularly significant. With specific pore sizes, they selectively allow the passage of fluids while retaining particles and microorganisms.

Depending on the application's specific requirements, filter membranes can be made of various materials. Common materials include polyethersulfone (PES), polyvinylidene fluoride (PVDF), nylon, polysulfone, and polytetrafluoroethylene (PTFE). These materials are chosen for their compatibility with the filtered fluids and durability.

Besides IV Infusion application, filtration technologies are also commonly applied in other medical procedures, such as:

  • Parenteral Nutrition

  • Transfusion Therapy

  • Chemotherapy and Drug Delivery

  • Critical Medication Delivery

  • And More

Stay tuned for our upcoming news of KBMED medical disposable products with innovative filtration technologies and relevant articles, where we will delve deeper into specific aspects of filtration technologies and their impact on medical device design and safety.
