Research is needed to determine the minimal level of protection needed when resources are not available for N95 air-purifying respirators since the pandemic threat from H5N1 and other possible influenza strains will exist for the foreseeable future.
Specifically, the most significant trends, drivers, and restraints that impact each of the six main product markets (disposable respirators, non-disposable respirators, powered air-purifying respirators, self-contained breathing apparatus, escape respirators, and airline respirators) are identified and analyzed.
Masks, Reusable Masks, Powered Air-Purifying Respirators,
a world leader in the design, development, and manufacture of powered air-purifying respirators (PA-PRs) for chemical, biological, radiological, and nuclear protection, has a new PureAir[TM] Bio Response Kit.
Particularly, formalisation of standards for equipment providing protection against chemical, biological, radiological or nuclear (CBRN) materials will provide new market opportunities, especially for powered air-purifying respirators and escape-only equipment.
In this research, Frost & Sullivan's expert analysts thoroughly examine the following markets: disposable masks, reusable half facemasks, reusable full-face masks, powered air-purifying respirators (PAPR), self-contained breathing apparatus (SCBA), airline equipment, escape-only equipment and integrated systems.

Unlike powered air-purifying respirators (PAPRs), which draw ambient air through a HEPA filter and blow it over the face at such a high flow rate that no unfiltered air is entrained during inspiration, surgical helmets filter air through the hood material itself.
