Filtering though activated charcoal?
The one that I have is not a disposable charcoal filter.
It is mostly carbon, but doesn't perform like all of the lower quality companies. They won't say what the proprietary purification units are made of or how they are made. What I was told many years ago is that they have silver which continuously disinfects over their lifetime. That has proven true for me.
Here's the conservative lifespan and how to clean them. Depending upon water quality used will determine how often to clean.
The labor involved is carrying water from source, ie. Sink, to the unit. This is why I like mine for convenience. Top chamber holds 5 gallons. Lower holds 6. I store the purified in glass 1 gallon jars and pour from half gallon pictures for ease much of the time.
