I was confused by this because I thought glass blocked UV, but apparently it lets UV-A through and only blocks UV-B and UV-C: https://hps.org/publicinformation/

I also found a study that suggests UV-A might not be effective against viruses (although at a guess they're not a common contaminant in drinking water compared to bacteria): https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8701782/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8701782/

- hutzlibu 3y agoBorosilicate glass does let UV-B pass. https://en.m.wikipedia.org/wiki/Borosilicate_glass https://en.m.wikipedia.org/wiki/Borosilicate_glass Quite a bit more expensive, though. And even better would be pure SiO2, fused quartz/silica. https://en.m.wikipedia.org/wiki/Fused_quartz https://en.m.wikipedia.org/wiki/Fused_quartz
