Review on 💧 Enhance Water Quality with Brita 35503 Standard Replacement Filters by Reggie Stewart

The filter was purchased to replace the old ones as advised. I have bought this product twice. The first time after switching to a new filter a few days, I found small black "sands" at the bottom of the jar. As this was purchased from a seller on Revain and not Revain directly I thought it might be the seller's problem. (and I wrote a long review about it, but Revain turned it down, saying I should contact the seller direct.) Now I've bought it again direct from Revain. Still the same problem. Pour out the water, wait 2 minutes, let it settle, there are particles on the bottom. It definitely pollutes the water, doesn't purify it.
