A Berkeley, California friend’s Facebook post:
given #B117 mutation, masked protection needs to be intensified
I’m doubling down, with cloth on top of N95 (thx Mitt Romney)
Also bought a little neck fan for blowing air – designed to cool off the wearer, when inverted it nudges incoming air away from my mouth
Stacking layers in my SafetyLasagna (which includes vitamin D in the AM, saline spray to line my nasal passages, then these crazy additions)

Although this inventor is a Dr. just like Dr. Jill Biden, MD, his California friends are not impressed:
My understanding is that fans, while protective for the wearer, actually increase the risk to others by blowing exhaled virus farther. I would steer clear of anyone I saw in public with a fan near their face.
Your fans could harm others if you were unknowingly covid+
I have read that the masks with the valve are not appropriate as a virus barrier, but are intended to prevent dust inhalation–so they let your breath out but prevent particles from coming in. You have an N95 underneath, so not an issue here, but since this is an opportunity for community review of a safety plan, wondering if you have thoughts there. Stay healthy! #SafetyLasagna
We actually do know that fans increase projection of viral particles. If you are wearing a fan, you increase risk of transmission from you to others, but also from others to you, just by stirring up a lot of air near the face.
I told him that I thought it would be simpler to eat real lasagna until his BMI hits 40 and thus get higher priority for the vaccine. A friend from MIT with some mechanical engineering ability:
If he is going to bother at all, which is debatable, he should use a P-100 respirator and NIOSH approved goggles. If you are really that concerned, add a faceshield. Doubling two useless filters ain’t going to do it…. P-100 filters are 167 times more efficient than N-95 (which are 10-20 time better than surgical masks). You need an elastomeric/plastic seal on your face or you aren’t getting to the next level. Some N95s have such seals.
Readers: Who has seen some interesting PPE solutions lately? The LG PuriCare (N95-ish mask with fan assist), announced in August, doesn’t seem to be available in the U.S., but online retailers in Hong Kong show that it is in stock there for HK$1,180 ($150 in the currency that Jesus prefers everyone to use).Full post, including comments
