Longer showers consume enormous amounts of energy and potable water. I was wondering if there was a way to recirculate so you can have an endless shower.
I am not alone. It is a thing. There is a way to solve for this! Enter the recirculating shower.
Or
Color me a bit skeptic that such a filtration system can remove soap and oil residue from used shower water.

I guess they’ve done quite a bit of research. Not sure I’m qualified to comment on the validity of their conclusions.
I’m also curious how frequently the filter materials need to be replaced.
I imagine the filthy bit at the start gets processed linearly, then when in the long shower phase the recirculator on.
