Breathing Filtration Capabilities

Our SLS team can support with your breathing filtration requirement. Explore our capabilities listed below and contact us for any specific application.

We Can Support With Your Breathing Filtration Requirements


Our global network of applications scientists provides technical guidance and laboratory testing to meet your breathing filtration requirements. Pall Medical Scientific and Laboratory Services (SLS) offers solutions for both healthcare providers and original equipment manufacturers (OEM) customers.  The latter can be e.g., a filter qualification protocol for the anaesthesia setting or an endo- surgery procedure. Aside from the capabilities of our own laboratories listed below, we can also support other application test requirements for you via our network of approved external laboratories.


Humidification Testing



This test method is used to evaluate HME (Heat and Moisture exchange) efficiency by measuring the water loss from an artificial patient (gravimetric method). This test meets the requirements for the international standard ISO 9360-1. This test is important to understand the ability of an HMEF to act as a passive humidifier in anaesthesia and in long term ventilation.



Measurement of Pressure Drop & Gas Leakage



The purpose of these tests is to measure the air flow resistance and leakage of a breathing circuit filter according to ISO 9360-1.  It is essential to be able to understand the ability of the filter to maintain low flow resistance in relation to different anaesthesia and intensive care ventilation settings over its entire life.



Drug Nebulization



Nebulized drugs may interact with the filter media and increase flow resistance. We can test for compatibility of nebulized formulations using mechanical or electronic nebulization per customized protocol to validate filter performance in a specific application. The purpose of this test is to understand the filter resistance and ability to deliver the standard nebulization procedure.
