Redding doctor says there is an extra layer of protection against COVID-19 available.
It's a local TV news report from an ENT doctor in Redding, CA, who shows how to add Povidone-Iodine 10% solution to over-the-counter nasal sprays to create an antiseptic barrier in the sinus cavity.

I plan to use the Neti Pot refill packs to add to the water. They are a mixture of sodium chloride and sodium bicarbonate.
RE: boiled water...
I can use some advice here. I have a water softener system (with charcoal filter) in my house, with an additional reverse osmosis triple-filter purifier in my kitche. This is supposed to purify my water down to about 10 parts per million.
I'm assuming that this is good enough to avoid boiling or distilling my own water?
