Review on Filter pitcher Aquaphor Provence A5 4.2 l white by Danuta Sk ᠌

The jug filter is beautiful, at first glance it looks like glass, it certainly pleases with the volume, for the first time it poured water, it went black, well, as I understand it, it’s coal, drained it, re-filled it and the water is clean, just in case I’ll skip the water again, but I didn’t understand how does the counter work, what should be done with it?! Good price, bought at a discount for 699)
