I wonder whether the results change with the pressure cooker.

I had ilizarov apparatus[1] on my legs for over a year(once during age 7 and another during age 15) and my mom used to sterilise the instruments (Scissors, Forceps) used for dressing wounds at home(every alternate day) in pressure cooker(on advice of the doctor).

I presume, pressure cookers are still being used for the sterilisation of instruments[2] in several parts of the world as its still common than an electric cooker.

SARS Cov-2 infectiousness decays exponentially, with the time constant a function of temperature and humidity. A two-parameter calculator: https://www.dhs.gov/science-and-technology/sars-calculator

Sounds like wetting the towel first would be the way to go.

I am sure they perform sterilization effectively, but introduction of water/steam (which is under pressure in a "pressure" cooker) will almost certainly deform a mask like an N95 mask.

I thought electric cooker uses less water in contrast to no water.

if your concern is corona, there's no need to do any of this for most people, most of the time (i.e., not a front-line worker). the likelihood of getting live corona on the mask is pretty low, and any corona that does get on the mask will die naturally overnight. certain situations like going to a party might warrant it, but in that case, just throw the mask away and use a new one next time. if you're more worried ab…

And the reasons people ask for citations is what you are saying is very misleading. The CDC estimates that 45% of US Adults fall into these increased risk categories. So no, it's not just people fighting off cancer it's almost half the country. > We estimated that 45.4% of US adults are at increased risk for complications from coronavirus disease because of cardiovascular disease, diabetes, respiratory disease, hyper…

none of that makes any difference. basically no one needs to disinfect masks, including those at elevated risk (emergency personnel and hospitals facing shortages the likeliest exceptions). just wear your mask at appropriate times (indoors when you can't distance from strangers for extended periods of time). regular folk don't need to do more than that.

Do not do this. Pressure cookers exist to accelerate cooking, by raising the boiling point of water above 100C, because pressure resists boiling. All plastics in the mask will deteriorate rapidly.

Earlier quoted context omitted.

I see that in general, but if we're wearing N95s specifically to protect against the coronavirus then several days seems like it should be (a) enough and (b) not as hard on the mask?

This is what I do. I just place it in a plastic bag and don't use it for about a week. I have enough to let me use one each day and quarantine the used mask for a week.

What's the plastic bag for? Seems like a good way to promote bacterial and fungal growth.

I bought one of these UV sanitizer boxes to sanitize my N95s: https://www.amazon.co.uk/gp/product/B085XZPLVS/ref=ppx_yo_dt... I'm still not totally certain how well it really works, but I know it works better than those UV wands (you need at least a few minutes of exposure). It's also neat for a few other things that it's probably healthy to sterilize a bit more frequently (e.g. keys, phone, toothbrush heads).

Yup, my wife went all out and got one of those UV sanitizer boxes[1] too along with the Under Armour face masks[2]. Their instructions say to wash it but it's convenient to just place in a box. We have also been cleaning other items in there including baby toys. [1] https://lumolite.com/ [2] https://www.underarmour.com/en-us/p/ua-sportsmask/1368010.ht...

I can understand how UV light can sterilize hard surfaces like a cell phone, but how does it sterilize multi-layer fabrics where the virus may be shaded from the UV light by the fabric?
