Ultipor 100 Breathing System Filter

Features and Benefits

  • Smooth housing profile
  • Pleated hydrophobic membrane
  • Optimal humidification
  • Compatible with nebulisation
  • Effective microbial barrier
  • 100% integrity and efficiency tested during manufacture

The Pall Ultipor 100 is a pleated hydrophobic membrane breathing system filter with a smooth housing profile for use in intensive care and anaesthesia. It provides:

  • Optimal humidification: Physiological levels of humidification are maintained, even at high flow rates and in long term ventilation. Clinical humidification performance is comparable to hot water bath systems and hygroscopic HMEs1,2,3,4.
  • Compatible with nebulisation: Medications can be nebulised between the filter and the patient.
  • Effective microbial barrier: The pleated hydrophobic membrane provides effective protection against airborne and liquid borne micro-organisms. This assures protection against cross contamination between patients in anaesthesia5,6,7 and can contribute to a reduction of ventilator associated pneumonia in long term intensive care ventilation4. The filter has been validated to remove Mycobacterium tuberculosis8, Staphylococcus aureus9, Hepatitis C virus6 and HIV10.
  • Extended life: When nebulisation is not used.


Pall Total Quality and Performance Guarantee

Each Pall Ultipor 100 breathing system filter is individually tested during manufacture for:

    Filter Integrity - assuring housing and seal quality.

    Filtration Efficiency - using a non-destructive test, assuring membrane quality.

    A Product Validation Certificate that is batch and customer specific is provided that details testing and validation. This is the customer’s guarantee of 100% reliability, performance in use and assurance of protection of breathing systems and equipment, patients and staff.
