I’m buying a 8L glass water jug and was wondering how many pieces I would have to put into the jug to filter the water or do you do any larger sizes ?

We are advising our clients to use 1 charcoal per litre of tap water to filter it effectively. The more charcoal you add the faster the filtration is . To be fair, the filtration results will depend mostly on the taste of your tap water. So if the water has a ok taste to start with , it should take not time to filter it. If the water is hard , you may have to wait a lot longer to taste the difference. Hope this helps The Present Store

At least one of the four charcoal doesn't seem want to sink even after boiling, is there anything I can do? Can I ask for a replacement?

I’ve never had this problem, I’d maybe contact the seller or amazon customer services and get another sent out

I don’t know how it’s made but it certainly works!

The water tastes of the charcoal. Does this sound right? Thanks.

No. Our water tastes lovely. We have two jugs and it tastes fine.
