Question: Can I reuse a disposable medical mask if I disinfect it?

Answer passage (source: WHO):
page_title: Q&A: Masks and COVID-19
section_headers: What types of masks are used against the spread of COVID-19?
section_content: Medical masks (also known as surgical masks): these are made from a
minimum of three layers of synthetic nonwoven materials, and configured to
have filtration layers sandwiched in the middle. These masks are available in
different thicknesses, have various levels of fluid-resistance and two levels
of filtration. These medical masks reduce the transfer of saliva or
respiratory droplets from the wearer to others and to the environment. They
also decrease the likelihood of potentially infectious droplets from others
reaching the mouth and nose of the mask wearer.
Hand hygiene should be performed before putting on a clean mask and after
removing the mask. These masks should be worn tightly around the chin and top
of the nose. The wearer should avoid touching the mask while it is on the face
and the mask should be immediately discarded if it becomes moist. Importantly,
wearing a mask must be combined with other preventive measures including
performing frequent and appropriate hand hygiene and physical distancing of at
least 1 metre (3 feet).
Respirators (also known as filtering facepiece respirators --FFR) and
available at different performance levels such as FFP2, FFP3, N95, N99):
these are specifically designed for healthcare workers who provide care to
COVID-19 patients in settings and areas where special medical procedures are
undertaken. Respirators are intended to protect the wearer when these medical
procedures aerosolize smaller particles than normal droplets into the air in
the health treatment area. Healthcare workers should be fit tested before
using a respirator to ensure that the respirator is sealed tightly on the
wearer’s face and is properly fitted. Respirators with valves should not be
used as the purpose of source control.

Reviewer feedback on this answer:
Doesn't address question.  It gives details that really don't address the reusability of masks or what to do with DISPOSABLE masks.
This answer states what a mask is.  It is relevant, but it doesn't answer the question at all.

page_title: Q&A on coronaviruses (COVID-19)
section_headers: How to properly wear a medical mask?
section_content: If you choose to wear a mask:

Before touching the mask, clean hands with an alcohol-based hand rub or soap and water
Take the mask and inspect it for tears or holes.
Orient which side is the top side (where the metal strip is).
Ensure the proper side of the mask faces outwards (the coloured side).
Place the mask to your face. Pinch the metal strip or stiff edge of the mask so it moulds to the shape of your nose.
Pull down the mask’s bottom so it covers your mouth and your chin.
Do not touch the mask while you are wearing it for protection.
After use, take off the mask with clean hands; remove the elastic loops from behind the ears while keeping the mask away from your face and clothes, to avoid touching potentially contaminated surfaces of the mask. 
Discard the mask in a closed bin immediately after use. Do not reuse the mask.
Perform hand hygiene after touching or discarding the mask – Use alcohol-based hand rub or, if visibly soiled, wash your hands with soap and water.

Be aware that there is a global shortage of medical masks (both surgical masks
and N95 masks). These should be reserved as much as possible for health care
workers.
Remember that masks are not a substitute for other, more effective ways to
protect yourself and others against COVID-19 such as frequently washing your
hands, covering your cough with the bend of elbow or tissue and maintain a
distance of at least 1 meter from others. See basic protective measures
against the new coronavirus for more
information.
Follow the advice of your national health authority on the use of masks.

Reviewer feedback on this answer:
It does give the answer clearly but gives so much other detail that it's a bit confusing. Still number 9 says get rid of disposable mask. That's the question.
There is a lot of information about wearing a mask.  It directly answers the question in one of the bulletpoints.

page_title: Q&A: Infection prevention and control for health care workers caring for patients with suspected or confirmed COVID-19
section_headers: Can disposable medical face masks be sterilized and reused?
section_content: No. Disposable medical face masks are intended for a single use only. After
use they should be removed using appropriate techniques (i.e. do no touch the
front, remove by pulling the elastic ear straps or laces from behind) and
disposed of immediately in an infectious waste bin with a lid, followed by
hand hygiene.

Reviewer feedback on this answer:
This directly answers the questions about a mask.  It states not to wear a mask twice and why.
This is good because it's clear. That's what people want when they look up something. No. Good.
