Joe of The Dude Abides sends greetings, and has a request for suggestions:

Hey Tom…

Question for you:

My First Need water filter bit the dust and I need to get another one. Can you point me in the right direction & recommend a replacement?

Money really isn’t an issue, and I would prefer if it filtered down to the virus level.

I usually just take my Katadyn HIker along, though I suspect it doesn’t catch viruses

If any of y’all have researched this in detail, leave a comment and pass it along.
