Disinfecting N95 and Surgical Masks - The Right Way!
Masks Will Help Protect You. The virus lives within droplets. Droplets cannot get through the mask.

Here you go folks.
Legit information from Dr. Peter P. Tsai, inventor of the electrostatic charging technology that makes the filter media of face masks including medical and N95.


Q1: Can the masks be treated by heat?

A: Yes as indicated in Figure 1, it is reported (if it is true) that COVID-19 cannot survive at 65C for 30 minutes. Therefore, it is safe to treat the masks in hot air at 70C for 30 minutes and this process can be repeated multiple times to reuse the masks without a noticeable loss of efficiency.
...
In such a case, respirator N95 is recommended to protect against suspended submicron virus to stop them from penetrating through the respirator body as well as from the edge leakage. The size of a corona virus is 0.08 – 0.12 μm (or 80 -120 nanometers). However, it is always survived with a host, which is bigger than the virus per se. But the host can be a suspended submicron droplet/particulate.

Never in microwave if there’s a metal strip on the mask to fit around nose.

As long as the metal has no points your fine.
Stick a metal spoon in the microwave for 30 seconds.
Now stick a fork in the microwave for 3.

Report back your findings

most masks have a thin METAL strip right at the nose

if you pop one of your N95's in the Microwave, it will explode or catch fire because of the METAL

I have the perfect way to do this safely.

The temp recommended in Fahrenheit is 150 degrees. A jerky making dehydrator runs at 165 degrees and has a fan to blow the air through the mask.

Make you some N95 jerky. My mask is getting sanitized as I type.

I would imagine hospitals would use hydrogen peroxide vapor to sterilize masks in bulk. Masks can be sterlized 50 times without breakdown of fibers. The elastic bands though degrade somewhere between 20-30 times.

Q2: Can the masks be treated using alcohol?

A: No. Face masks cannot be sterilized using alcohol because the charges will be erased by either alcohol liquid or its vapor, as described above.

You know most people dont realize to put the mask or in it's most protective state you have to do the fit test

This is how they make the people in the medical field get a good fit with these mask

My redid hers last night

They spray this spray which has a smell, when you can smell it then the mask is fitted properly

They also wear another regular mask over this one, this way if droplets hit the mask it will bit the outside mask and not affect the N95 mask

I just spray mine with 70% isopropyl alcohol (on the inside and outside surfaces) using a regular trigger spray bottle set to a fine mist. 30 seconds later, any coronavirus present is neutralized. Wait 5-10 minutes if you want the mask fully dry before reusing it (so the mask doesn't still have the isopropyl alcohol denaturing additive smell when breathing through it).

If you have two masks that you can put on rotation that works best, because you can use the second one while the first one is drying so there's no down time at all.
