I remember when covid hit and there was an N95 shortage on the covid unit, we had to don and doff the same mask over and over again. They told us we were allowed one mask per day, and we could reuse that one mask up to 4-5 days in a row as long as we put a regular mask on top of it. Looking at what’s grown on those Petri dishes, it really puts things into perspective.

Probably just sweat and dirt. There’s naturally going to be some edgy anti-maskers, so it’s worth pointing out that studies have shown that they work, including for individuals (even when crowds are maskless) and in real-world conditions as opposed to laboratory ones. Bit pointless me saying it though, those people don’t really care about “logic” and “science”. They’re too busy breathing in the QAnon cult. I say we put them in some island and dunk diseases there, see what they think then.

@GearsDatPowerDaTubes 2 года назад

Would love to see the condition of the mask in various stages, say after 1 "use" versus 5 "uses", maybe 40 hours would be better? Absolutely loved the electrostatic demo, super cool! One minor caveat is that these masks actually filter the worst at 0.3 micrometers. Anything smaller easily collides with the fibers due to Brownian Motion, anything larger is collected through impaction or electrostatic attraction. That's why these masks are tested at 0.3 micrometers... if it gets a 95% at that size, it probably gets much more at any other size.

@sci-inspi 2 года назад

Some sizes are filtered out better than others. There are a lot of nuances so I try to be very general given the limitations of presenting information through text on a screen. That's why I also included references.

Is it possible for a medical grade mask to be compostable? I understand that single use is necessary in the medical field, but I’m just wondering if it’s even possible to phase out plastic waste there. There’s so much. Masks, isolation gowns, gloves, caps, needles.. sooo much. Is there a sustainable material that can be waterproof?

@saniainez 2 года назад

For now, I don't think we have the technology. A high enough density is needed in gowns, gloves, and caps so nothing can seep through nor go through, and most of available natural materials can't really provide that. The mask in the video as you know is made of a mix of polyester fibers, which does a great job of trapping bacterias and viruses (which is also the reason pet owners rarely use plastic feeding bowls), and a cloth one doesn't have the same efficiency.
