Background A qualitative fit test using bitter-tasting aerosols is the commonest way to
determine filtering face-piece (FFP) mask leakage. This taste test is subjective and biased by …

Background This study was undertaken to determine the utility of an infrared camera (IRC)
for assessing leaks around filtering facepiece respirators (FFR) during quantitative respirator …

P2/N95 respirators or filtering facepiece respirators may not have the same pass rate on
quantitative fit testing. The aim of this study was to investigate the pass rate of four commonly …

Background In response to the COVID-19 pandemic, 6,287 Australian health care workers
(HCWs) were fit tested to N95 filtering facepiece respirators (FFRs). This study determined …

Aims To assess the effectiveness and acceptability of smartphone customised frame
technology to improve the fit of disposable filtering facepiece class 3 (FFP3) respirators for …

Infrared imaging (IRI) can detect airflow through and near respirator masks based upon
temperature differences between ambient and exhaled air. This study investigated the …

We have demonstrated the effect of covering an N95 filtering facepiece respirator (FFR) with
an overlying face mask. In total, 100 participants successfully completed quantitative fit …

As a continuation of recent studies to assess the accuracy of existing fit test methods, a multi-
donning approach to fit testing is presented. As an example of that approach, a multi …

ABSTRACT N95 filtering facepiece respirators are used by healthcare workers when there is
a risk of exposure to airborne hazards during aerosol-generating procedures. Respirator fit …

Fifteen subjects underwent three replicates of quantitative respirator fit-testing with N95
filtering facepiece respirators that were donned with the upper strap high on the occiput, as …
