Market potential

The global power air purifying respirator market size was valued at USD 1.91 billion in 2019 and is expected to grow at an annual growth rate of 8.5% from 2020 to 2027.

Favorable government regulations pertaining to employees’ safety and the emergence of several infectious biohazards are expected to drive the demand.

Increasing awareness regarding employees’ health and safety, coupled with rising industrial fatalities due to respiratory diseases and safety standards by regulatory agencies, such as the Occupational Safety and Health Administration (OSHA) and the European Commission, is anticipated to spur market growth over the long term.
