In addition to selling new respirators, the company wanted to offer the new exhalation filter and valve to those who already owned them. Maplewood, Minn.вЂ“based 3M developed a new exhalation filter and valve to fit its 6000 series of elastomeric half-mask respirators, which had been used occasionally in healthcare before the pandemic, according to Nikki Vars McCullough, director of application engineering and regulatory affairs in the companyвЂ™s personal safety division.

The proposed fixes may sound easy, but the companies had to figure out where and how to safely and comfortably channel wearersвЂ™ outbreaths without leaving them uncomfortably warm, according to NIOSH. HHS plans to buy some of the redesigned masks. Three companies - 3M, MSA Safety and Dentec Safety Specialists - recently gained NIOSH approval for elastomeric respirators they redesigned by either removing the exhalation valve or fitting it with a new filter and valve to trap the virus inside. Some healthcare workers had been using them during the pandemic, but the FDA became concerned last year about the possibility of spreading the virus through the exhalation valves. The exhalation valve enables wearers to breathe out comfortably and keeps the rubber masks from becoming too hot. The makers of reusable elastomeric half-mask respirators designed them for industrial use with two inhalation valves flanking an exhalation valve.

The face of the next pandemic could be very different than that of COVID-19, thanks to a handful of companies that have redesigned reusable industrial face masks to better protect healthcare workers and help prevent mask shortages.
