Joseph G. Allen, Akiko Iwasaki and Linsey C. Marr: This Winter, Fight Covid-19 with Humidity →

Hat tip to Joshua Hausman. Joshua mentions that while the article says 40% humidity won’t be too hard on your house. But that depends on temperature: below about 20 degrees Fahrenheit, even 40% humidity is likely to lead to significant condensation. But the general idea still holds: figure out what level of humidity is OK for your house given the outside temperature and go up as high as that level.
