Mask re-use

https://www.msn.com/en-ca/health/medical/manitoba-researchers-say-theyve-found-the-answer-to-global-shortage-of-n95-masks-amid-covid-19-crisis/ar-BB124e0i?ocid=spartanntp

Over the past few weeks, I've shared nitrile gloves, polycarbonate safely glasses, N-95 respirators, and P-100 half-mask twin-cartridge respirators with 9 households.  Each household received 2 pairs of safety glasses, 50 pairs of nitrile gloves, 7 N-95 respirators, and 1 P-100 half-mask, twin cartridge respirator with 6 pairs of extra cartridges.  My guidance to each household was as follows: 

Wear your safety glasses at all times when you leave your home.  Clean the safety glasses after each use with a cotton disk make-up remover and isopropyl alcohol with a minimum of 72% strength.  (Clean your credit card and your key fob, too.)  

Put on a pair of nitrile gloves before you leave your car to run errands or go shopping.  After returning to your car, remove your gloves and isolate them in the trunk or in a designated container.  Apply hand sanitizer to your hands and wrists.  Do not discard the nitrile gloves.  Instead, soak them for several minutes in a solution of 2 tablespoons of sodium hypochlorite to 1 gallon of bleach.  Hang them indoors to dry, sort of like the way we used to display our Christmas cards.  After they are thoroughly dry, write the date on the cuff, and simply wait until you have run out of new gloves before you re-use the ones you washed.

The half-mask P-100 respirator with the twin cartridges is intended for use in situations of extreme risk, such as caring for someone who has symptoms.  It is intended to be reused.  Between uses, all surfaces should be wiped with alcohol and the respirator should be protected from contamination with a plastic bag.  The cartridges should only be replaced if you experience difficulty breathing, which would indicate a build-up of dust on the surface of the filtration medium.

The 7 N-95 respirators are intended for limited use of approximately 30 to 45 minutes per day in moderate-risk situations, such as grocery shopping.  Each respirator should be isolated for a period of 7 full days between uses, so you might as well begin by assigning a day of the week to each N-95.  (Using a laundry marker, write the name of the day on an elastic band, or on the inside.)  After returning to your car, and after removing your nitrile gloves and sanitizing your hands, remove the respirator by the elastic bands and isolate it in the trunk or in a designated container.  Sanitize your hands again before entering your car and touching any of the control surfaces.  (At this point, I usually wear cotton gloves.)  Isolate your gently-used N-95 respirator inside a brown paper lunch bag until its designated day of the week rolls around again.  Do not put it into a plastic bag.  Do not wipe down any surfaces.  Do not attempt to wash it.  Do not spray it with any chemicals.  All it needs is a chance to dry completely and thereby dessicate any microscopic organism that might have been trapped within the filtration membrane.  To accelerate this process, place the N-95 on the dashboard of your car under the mid-day sun before storing it inside its designated lunch bag.

Personally, I do not use any N-95 respirator unless I'm doing carpentry, drywall, or landscaping work.  Why?  Because a filtration efficiency of only 95% of particles of 2 tenths of a micron or larger is not good enough.  I only use P-100s.  There are several other reasons for this, all of which can be found on page 13 of "Becoming Self-Sufficient", which is linked below.

I wonder about the efficacy of dipping the mask into water with dish washing detergent and letting it dry. 

The sufficant would break the virus cell walls therefore sterilizing the mask. 

Maybe an option??
