What it does not tell you
The XRS level measures breathing comfort, not protection. To know what this mask filters, look at its protection class (for example FFP2, N95, KN95) and the manufacturer's instructions. An XRS level never replaces a safety instruction.
How it is measured
A laboratory measures the effort needed to draw air through the new mask. This level corresponds to a specific resistance below 30 Pa/(L·s⁻¹).
