True, it's much more complicated than just time vs money.
With the built filter you learn a skill, but how do validate that the produced water is clean ?
With the bought filter (berkey or otherwise) I would certainly expect the filter mounts to be fail-closed, if that's not the case for something as vital as water then the whole thing is useless.
Unfortunately I searched online for serious tests of such devices and found pretty much nothing, always the same stupid comparisons parroting the manufacturer's marketing/advertisement points and that's it![[Image: sad.gif]](https://rooshvforum.network/images/smilies/sad.gif)
