You taken the I-MASK+ protocol?
If I wasn’t a first responder I would have just used this and I have Ivermectin just in case.
I was fitted for an N-95...and I use one.....when seeing Pt's. I've double masked many times...but it's irritating..to my eye's and skin.
As is the N-95,,,by itself.
I test myself everyday I work...there. Not a swab....just a Temp/ Cough/ Smell loss/ etc....
Seems to work...
