Going back to my fanny-pack, bleach and water bong.... the bleach thing.... breathing that, even through a long tube might be an issue. Solution... add an activated charcoal filter in the tube. That should work. No viruses are getting by my bong/charcoal/fanny-pack breathing apparatus.
I just checked, I can draw air through a (new) Brita water filter... so if any of you want to make a redneck "country-boy can survive" Youtube how-to video... there ya go.
Build it yourself for under $20. Works forever, just add bleach and water.
