Some accessories to the Omega fold Face Mask Mark 8. I wore it for 2 hours yesterday cutting foam cushion for the face shields and the rubber bands directly on the skin is chafing. 1. Use strips of paper towel to cushion the back of the ear. 2. The Bounty towel is 2 ply and becomes 4ply when folded. But I’m breathing too comfortably. An N95 mask is harder to breathe in. So I folded a Kleenex tissue and sandwiched it in the “taco shell”. Now the breathing is more restricted but still comfortable. Looking for a better “filter material” than the tissue. Will update when I find something suitable. 3. Folded aluminum foil into 1/4” wide strip about 6 layers thick, since we aren’t in kindergarten and have pipe cleaners laying around. Paperclip are too stiff. 4. A index card plate to give it more rigidity and shape. Now it just holds its shape without wearing it. ** Need to add the hexagonal plate after popping the mask open. Then open the mask from the bottom and slide the index card in front of the printer paper to keep it rigid. Hope that makes sense. Let me know if you have any questions.
Learn to make a structured, no-sew, disposable face mask using a paper towel, printer paper, 2 rubber bands (#19 size 3 1/2”x1/16” best size) and 2 staples. To give the mask structure, requires some skill equivalent to folding a paper airplane.
Introducing the Omega Fold Face Mask (Mark 8). #omegafoldfacemask
Double Board Certified Surgeon Dr. George Yang designs a free DIY Double-layer Paper Towel face mask for immediate use while waiting for purchased surgical or cloth face masks to arrive. If you like the fit of the Omega Fold face mask, the main benefit is convenience of having a plentiful disposable clean face mask without the added work of washing them.
California and New York has mandated everyone who is outside their home to be wearing “non-medical face covering” while still maintaining #socialdistancing (6 feet of separation) from other people to avoid a deep breath of Coronavirus aerosol from an infected person.
We are instructed to not purchase any N95 masks and let the Healthcare workers surrounded in close contact (less than 6 feet) with likely Coronavirus aerosol in the air they are breathing.
The main goal of “non-medical face covering” is to 1. keep the nose and mouth covered to prevent the an asymptomatic infected user from openly spraying sneeze or cough droplets into the air which may land on surfaces or a person’s hand and 2. prevent a non-infected user from accidentally touching their nose or mouth with their own hand after receiving Coronavirus droplets from a hand shake, door knob, ATM or elevator button, etc.
Non-medical face coverings or even surgical face masks will not protect the user from Coronavirus aerosol (floating microdroplets) from being inhaled. Medical experts are reporting that the aerosol route of contracting Coronavirus is much lower than the droplet transmission from a contagious Coronavirus carrier with or without symptoms or inanimate objects (fomites) which that person has touched with a contaminated hand (sneeze or cough into their hand.)
A recent study from the Lancet published April 2, 2020: Stability of SARS-CoV-2 in different environmental conditions. Chin A, Chu JT, Mahen RAP, Hui KPY, Yen HL, Chan MCW, et alolan. They studied how long the Covid-19 Coronavirus survived on different surfaces and environmental conditions. https://www.thelancet.com/journals/lanmic/article/PIIS2666-5247(20)30003-3/fulltext
A microdroplet (5 ul) of Coronavirus was placed on various surfaces then tested for recovery of the virus after various amounts of time.
Tissue and printer paper: No detectable virus after 3 hours.
Wood and cloth: No detectable virus after 2 days
Glass and banknotes: No detectable virus after 4 days
Stainless steel and plastic: No detectable virus after 7 days.
Surprisingly, on the outer layer of a surgical mask a detectable level of virus could still be present (~0.1% of original virus in the micro droplet.)
