In-line IV filters are designed to be placed in-line between the  intravenous solutions being administered and the patient. They come in different physical sizes, pore sizes and with different filter media (such as polyethersulfone or nylon) and can be charged or uncharged. Dependent on media type, size and pore size they can be used with a variety of infusion protocols and drugs classes, such as protein-based drugs, clear fluid medication or lipids.

In-line IV filters are medical devices used with IV administration set to remove inadvertent contaminants including particles, air, microorganisms and associated endotoxins and enlarged lipid sets before they enter the patient's bloodstream.

• Particles 


• Lipid droplets  


• Microorganisms 


• Endotoxin  


• Air 

Yes. for example Perez et al. demonstrated that the introduction of Pall Medical in-line IV filters in multidrug infusion lines typical for pediatric intensive care unit patients led to a significant reduction in overall particulate matter.

Filter pore size should  be selected dependent on the fluids or medication you administer intravenously  to the patient.



0.2 µm are for clear fluids

1.2 µm can be used for lipid containing solutions.
