3. Schematic summary of
current international
guidelines on re-use,
reprocessing, and
extended use of
single-use masks and
respirators

4. While extended use or re-use of single-use surgical
masks or respirators (with or without reprocessing)
is generally not recommended, guidance from
various organizations supports such measures
(preferably extended use rather than re-use) as a
last-resort measure during critical shortage.

6. Comparisons across guidance documents
and systematic reviews highlight limited
evidence, varying levels of detail, and areas
of inconsistency, especially in relation to re-
use of respirators (with or without
reprocessing) during and after aerosol
generating procedures.

8. The reprocessing of surgical masks is not
ecommended.

10. Where extended use or re-use is being practiced,
healthcare facilities and institutions should ensure that
policies and systems are in place to enable these practices
to be carried out in the safest way possible in line with
available guidance.
