Description
The Trend Stealth Air respirator has valves that makes it inappropriate for COVID-19 purposes. You can pop out the exhalation valve and pop in this plug (with the slanted end in) instead, and then pop out the inhalation valves so that air goes in and out via the N100 filters.
The result is pretty comfortable for breathing: I've been using it at the gym for months now.
