Hi all
While sorting through an old box in the loft I came across a water purifier that I bought about 20 years ago and forgot I had.
I was wondering if the charcoal in the purifier woud still be Ok to do it's job as it only had a few pints of clean water pass through it to test itwhen I first had it.
It is a PWP Personal Water Purifier.
I know I could ask the manufacturers but wondered if any of you science types may be able to help.
Picture of one very much like mine
Can any of you guys and gals help.
Thanks Phill
