Eitan Medical Sets Filters - Frequently Asked Questions 

Select Sapphire administration sets have integrated filters manufactured by PALL Medical or GVS. Filters are available in different pore sizes that enable retention of particles, bacteria, and fungi as well as eliminate air.

Here are some commonly asked questions & answers about filters:

To determine whether you have a PALL filter or a GVS filter in your set, look at the housing of the filter. If the housing of the filter is in the shape of an arrow, it is a PALL filter. If an arrow is printed on the housing of the filter, it is a GVS filter.

The filter contains an air vent and membranes. Fluid enters via the inlet through the vented component, and then passes through the filter. When primed correctly, the membrane will become wet and will not permit air to pass forward towards the patient.

1.2 and 0.2 micron filter options are available.

Filter manufacturers have conducted membrane binding studies that demonstrated that the membrane, which serves as the filtering mechanism of the filter, has been shown to be low drug binding.

Yes. Hydrophilic membrane material is polyethersulfone (PES), which is considered low protein binding.

Prior to use:

Always read and follow instructions in the user manual.
Close at least one clamp on the administration set.
Remove protective cover and insert spike into the solution container.

  1. Verify the administration set is disconnected from the catheter/access site.
  2. Open all clamps of the administration set and make sure there are no other occlusions blocking the set.
  3. Priming: Please note that the priming instructions in this step are different for GVS vs. PALL filters. Hold the filter so that the arrow side of the filter is pointing upwards (please download the Training Aid below for full instructions with images). 
  4. Allow the medication to prime the filter, wetting the filter membrane and eliminating air. Once all air has been removed and fluid is observed at the end of the set, priming is complete.
  5. If after priming, a patient is not connected to the administration set, close the clamp below the filter until the patient is connected.

Ensure administration set’s end cap is secure.
Close clamp below filter.

Always maintain the position of a properly primed filter at or below the infusion site.
