Betty, I just use 20 ppm Colloidal Silver (CS) from my two ounce spray bottle that I carry in my pocket. I use one spray in each nostril while inhaling deeply on that side. I will repeat every three to four hours if I am concerned about being in a crowded area as a Covid-19 preventative. In a neti pot I might dilute it to 10 ppm as 20 ppm may have a sting to it. I will also spray it in my mouth and back of my throat.
If I am already sick I will use a cold process vaporizer to inhale the silver into my lungs. Hot process devices don't work for CS.
