Clearly, the use of face masks looks like it will be with us for some time.
For the last 18 months or so I've been using a mix of disposable medical grade masks and a couple of washable ones. I generally find the disposable ones much nicer to wear and breath through and seem to fit better too. However, the very idea of them does not sit easily with my views on sustainability.
So as we always seem to have the answer to every possible purchase question on here.......what would anyone recommend by way of good reusable/washable face masks. Anyone who suggested flip flops in the slippers thread need not respond ;o)
Speak for yourself.
My personal view is fairly simple, if your going to wear the same mask more than once why bother wearing one at all. I wear disposables all the time and have a burn bag and lots of anti bac with me wherever I go.
My view may be skewed though having lived with a covid nurse that was off for 4 months when she caught it at work.

Make your own.
Why number of times worn important?
From what I was told by her care team, covid Is transferred by vapour so a mask could become contaminated at any time inside or out so if you put it on and bag it after use any contamination stays in one place, if you multi use it any contamination can be on your hand, pocket, handbag or car air vents, any place you store or hang the mask before putting it back on your face. It’s the transfer of contamination that was drummed into me.

Okay, though I'm always careful to clean hands before taking off and probably hang for at least a day (in house) to allow any virus to degrade before re-wearing.
I’d be asking serious questions about any masks / face coverings that promise to ‘kill’ viruses. What is the science behind it? What ‘real-world’ testing can be evidenced?
I use disposable masks, make sure they fit as well as can be, and ensure I take them off carefully.

To my mind, if there was a decent, reusable alternative, then surgeons would be wearing them.
We go through boxes of them at work, gloves too. Pre Covid, I’d change my gloves maybe twice a day, now it’s more like 20. If you want to justify it, I guess on balance the world is a greener place with all the working from home etc.
Oh dear. I've been using the same disposable mask for months. Just as well I don't meet many people. It is starting to get a bit smelly so I suppose I should change it.
There's a fair bit of expertise here so I am seriously asking for anyone to point me at any unambivalent examples of fomite transmission at all anywhere throughout this pandemic.
Because I can provide a shit-load that suggest that it's incredibly hard to catch covid from any surface.
For example:

I have used two masks in daily rotation (leaving one on the dash board and cleaning both at the end of the week) throughout the pandemic and supported by a decent ioniser in every room I teach in. I made an explicit choice to stop wearing a mask and turn off the ioniser - as mentioned here - and caught it inside three weeks. I don't think that is a coincidence. I stopped washing and sterilising my hands more than normal nine months ago.
You should. There are some really nasty moulds that could spoil your day...
I agree that formites are unlikely to be the main route of SARS-Cov-2 viral transmission, but I keep changing my masks for reasons such as the one you’ve highlighted here!
HeiQ’s Viroblock technology has been scientifically proven to effectively destroy a large number of viruses and bacteria, including SARS-CoV-2, the virus that causes COVID-19 (Peter Doherty Institute for Infection and Immunity in Melbourne, Australia; 2020).
It also offers proven antibacterial properties against: Candida Albicans, Staphylococcus Aureus, Mycobacterium Terrae and proven antiviral properties against: Sendai Virus, H3N2 Human Influenza A, H1N1 Human Influenza A, H5N1 Avian Influenza A, Human Coronavirus 229E, H7N9 Influenza A (2013), Respiratory Syncytial Virus, SARS-CoV-2 (COVID-19).

Oddly, I cannot find the first paper. It's not Harvard standard, but I really should be able to find it. Nor can I find an M.J on the Doherty staff:

It's hard to evaluate the claims when the linked papers either are not to be found or are not Sars. Perhaps more to the point, there are concerns about the long term toxicity of silver nanoparticles. There are plenty of papers on this. For example:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7177798/
The fact is that we now know that the virus has a very short period of viability on any dry surface. As such it just isn't necessary to kill it, just to stop it getting into the airways in an aerosol or droplet form. This is an example of 'It doesn't go black in the can' - sure, virus left on it becomes inactive, but virus left on any dry surface becomes inactive. Maybe it's quicker on this surface, but the onus is on them to prove it and this:

doesn't look like proof to me. It looks like smoke and mirrors.
Do you have any connections with this company and / or their product?
I can’t find their scientific publications - the references don’t seem to be in a usual format - are there links to the original, peer-reviewed publications?

Which? tested reusable face masks. Results here: https://www.which.co.uk/reviews/face...s-awLeA3A6XoZD
I have a few of those Bags of Ethics ones, comfortable and effective but the nose wire does snap in the middle after a while.
