This fountain is beautiful, but annoyingly loud. So much so, I replaced it.  If I had a large house I could put it somewhere that it was just a small tinkle of falling water, but I have a small house and it’s too loud. The filters have the same problem that I found in the reviews on your website, so, that’s not good either. The one I replaced it with is easy to clean, quiet and 80% less in money. I’m sorry this didn’t work for me, it certainly is elegant.
