Stills are good and they can be cheap.
I would look into a Berkey system with the fluoride ( PF-2) filters.
Gravity fed, no hydro needed, stainless steel, and the filters last a long time before you need new ones.
-- that is the real LSS short and I have spent hours and hours of research on them. I am trying to type less these days, with injuries and just people zoning out LOL
Here is a Canadastan side sample of what you look for and I would look for a package with this as well as the SIGHT SPIGOT so you know how much water is in the container.... my research showed for not much money, it is a big time saver and peace of mind thing.
The black filters are always the standard.
The white ones are the fluoride filters and go on the bottom side into the fresh water 2nd container.
The Big Berkey! Classic.
Thanks for the Amazon linkie to it; just added one to my cart.
