I don't think this is necessarily contradictory. Masks need to be worn correctly and not be reused. There's a good chance that a lot of people are wearing them incorrectly, and most people aren't going to have a sufficient supply on hand to avoid reuse. As such, they might give some people a false sense of security.
This article gets into some of the potential issues: http://blogs.hcpro.com/osha/2009/05/ask-the-expert-n95-respirator-reuse/ http://blogs.hcpro.com/osha/2009/05/ask-the-expert-n95-respi...
It at least seems plausible that for the average person masks won't do much good and that it's much more important for health care and public safety workers to have access to them.

- wideasleep1 7y agoInteresting, hadn't considered that one...how long and are the 'rubbers' holding up? Also cheers on that article...I've been finding it confounding that both masks and disposable gloves are NOT being preached in all media, if one must go into confining public spaces.
- fortran77 7y agoThe "rubber" seems to hold up fine. It's in a convection oven, I bring it to temperature, with a dish of water in it, and then bake it for 10 minutes. I have no idea if it's clean or not, of course.
- efuest 7y agoThat study is great, but why no UV-C tests? I’ve been using a UV-C decontamination box I made cheaply. It seems safe and effective for a couple of rounds of decontamination. https://www.nebraskamed.com/sites/default/files/documents/covid-19/n-95-decon-process.pdf https://www.nebraskamed.com/sites/default/files/documents/co...
- wideasleep1 7y agoWas just studying on Far-UVC (222nm) as being much safer than C, yet more effective (literally second(s)) to kill virus..I suspect we will see vast deployments of this light coming to public spaces near you. https://www.laserfocusworld.com/lasers-sources/article/16555364/uv-sterilization-faruvc-light-kills-airborne-flu-viruses-without-danger-to-humans https://www.laserfocusworld.com/lasers-sources/article/16555... https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0201259 https://journals.plos.org/plosone/article?id=10.1371/journal...
- nerfhammer 7y agoThis study tried several methods of decontamination including soaking it in alcohol or bleach or even baking it in a rice cooker. TLDR baking damaged it only slightly but alcohol and bleach significantly damaged it https://www.researchgate.net/publication/320361295_Filter_quality_of_electret_masks_in_filtering_146-594_nm_aerosol_particles_Effects_of_five_decontamination_methods https://www.researchgate.net/publication/320361295_Filter_qu...
