Laboratory studies have demonstrated degradation of electrostatically-enhanced (electret) respirator filter performance after exposure to excessive levels of ionizing radiation, immersion in solvents, and when exposed intermittently to specific aerosols. This study was conducted to determine if such degradation has practical significance in the workplace. N95, R or P95 and P100 filters from two manufacturers were tested. All filters were electrets except the P100 filters from one manufacturer…

Efficiency of Degraded Electret Filters: Part II - Field Testing Against Workplace Aerosols

Field tests were conducted to measure the efficiency of N95, R and P95 and P100 filters from two manufacturers against workplace aerosols. Three groups of each type of filter were tested: 1)

Comparison of pressure drop and filtration efficiency of particulate respirators using welding fumes and sodium chloride.

TLDR
Comparisons of respirators certified with a surrogate test aerosol such as NaCl are appropriate for filtering welding fume (based on penetration) and welders will need to choose which models are easier to breathe through for the duration of their use and replace respirators or filters according to the user instructions and local regulations.

Workplace field testing of the pressure drop of particulate respirators using welding fumes.

TLDR
The present study evaluated particulate respirator PD based on workplace field tests against CO(2) gas arc welding on mild steel in confined booths in the workplace and found that most welding fumes were trapped within the first layer, outer web cover, and second layer, in order, while no fumes were observed beneath the fourth layer of the tested respirators.

Evaluation of the Filtration Performance of NIOSH-Approved N95 Filtering Facepiece Respirators by Photometric and Number-Based Test Methods

N95 particulate filtering facepiece respirators are certified by measuring penetration levels photometrically with a presumed severe case test method using charge neutralized NaCl aerosols at 85

Powered, Air-Purifying Particulate Respirator Filter Penetration by a DOP Aerosol

TLDR
While laboratory tests show that the filtration efficiency of this electrostatic PAPR filter degrades with exposure to DOP aerosol, the observed laboratory degradation may or may not affect workplace performance, as similar degradation has not been verified in workplace studies.

EXPERIMENTAL RESEARCH OF DUST POWER OF FILTERING MATERIALS FOR ANTI-DUST RESPIRATORS

The purpose is to carry out experimental investigations of the physicochemical properties of filtering materials for the manufacture of two-layer filters of high dust capacity of dust respirators for

Effect of Decontamination on the Filtration Efficiency of Two Filtering Facepiece Respirator Models

TLDR
Filtration performance after decontamination using bleach, ethylene oxide, and a microwave oven was degraded for both respirator models, although particle penetration levels were still less than the NIOSH certification criteria.

Evaluation of a passive method for determining particle penetration through protective clothing materials

TLDR
A passive method that measures wind-driven particle penetration through ensemble fabric has been developed and evaluated and indicated greater sensitivity since penetration decreased in response to the increase in permeability.

Effect of surface charge density on electret filters charge degradation by organic solvent exposure

The effect of the surface charge density of an electret filter on its collection efficiency degradation via isopropyl alcohol (IPA) species exposure is discussed in this study. Five electret filters

TLDR
It is concluded that intermittent, low-level sodium chloride aerosol loading of N-95 respirators has a degrading effect on filter efficiency, but this reduction in filter efficiency was not accompanied by a significant increase in breathing resistance that would signal the user that the filter needs to be replaced.

The effects of particle charge on the performance of a filtering facepiece.

TLDR
This study quantitatively determined the effect of electrostatic charge on the performance of an electret filtering facepiece and found that the primary filtration mechanisms for the micrometer-sized particles are interception and impaction, especially at high face velocities, while electrostatic attraction and diffusion are the filtrations mechanisms for submicrometers-sized aerosol particles.

Effect of Facial-seal Leaks on Protection Provided by Half-mask Respirators

Abstract Applications are presented of a computer model that gives the performance (overall protection factor including filter penetration and facial-seal leakage) of half-mask respirators for

Loading and filtration characteristics of filtering facepieces.

TLDR
Experimental data show that the removal efficiency of these facepieces is reduced in time by as much as this amount, however, under normal wear conditions, the total aerosol particle load is not as high as shown and the filtering facepIEces are likely to be discarded before the fiber charges are significantly diminished.

Electrostatic respirator filter media: filter efficiency and most penetrating particle size effects.

TLDR
In all six of the filter models tested, filter penetration values increased considerably and the most penetrating particle size noticeably shifted toward larger particles, indicating the need for additional research to define environmental conditions that may affect electrostatic filter efficiency.

Respiratory protective device

TLDR
One aspect of the present invention provides a respiratory protective device providing a powered filtering device for controlling air flow between the inlet and the outlet(s) in response to a wearers breathing pattern.
