Ultipor® 25 Filter With Monitoring Port

Small Volume Breathing System Filter for Use in Anesthesia

Routine use of this device will protect the interior of the breathing system from patient-derived contamination, allowing extended use of the machine side of the breathing system when used with a Pall Ultipor™ Anesthesia Breathing Circuit System.*


  • Extends circuit life – enables multiple patient reuse of the machine side of the Pall Ultipor Anesthesia Breathing Circuit System and the CO2 monitoring line for up to 24 hours.
  • Reduces costs – lowers patient treatment costs by permitting use of Pall circuits on multiple patients.
  • Effective barrier – bidirectional, hydrophobic media provides protection against airborne and liquidborne bacteria, viruses, and particulate matter to 99.999% efficiency.
  • Low resistance – unique pleated hydrophobic membrane assures low air flow resistance in dry and wet conditions.
  • Easy port seal – tethered monitoring port cap prevents detachment from the filter and easily seals the port when not in use.

*When used with a circuit other than the Pall Ultipor Anesthesia Breathing Circuit System, please refer to the breathing system manufacturer for information on whether the system being used has been validated for extended use. Please contact your local Pall representative for more detail.

Performance
Vezina et al.10 performed an in vivo evaluation of three brands of breathing filters for their ability to retain Mycobacterium chelonae. The following table illustrates the average mycobacterial retention capabilities of the three products:

Table 1
Comparison of Three Brands of Breathing Filters for Retention of M. chelonae

NOTES:

  1. cfu = colony forming units
  2. The lowest M. chelonae recovery in a single trial for Brand A was 7.5 X 102 cfu.
  3. The lowest M. chelonae recovery in a single trial for Brand B was 6.0 X 102 cfu.
  4. This study utilized M. chelonae challenges that were not monodispersed, resulting in titer reductions for the Pall Ultipor 25 filter that exceeded 106 cfu. A more stringent monodispersed microbial challenge of the Pall Ultipor 25 filter is customarily employed during filter performance characterization testing by Pall Corporation. This testing utilizes the method of Duberstein and Howard,11 in which Brevundimonas diminuta and MS-2 bacteriophage yield 4-5 log titer reductions.
