Email Support@Naplesnaturals.com: While the design of this jug is generally acceptable, the efficiency of the filters is not very high. I use the third filter and this filter ejects charcoal splinters and tiny white spheres for the first twenty fills. Luckily I have a handy fine strainer that I can use to filter this residue out of any pitcher filled with water. Obviously you are having quality control issues with your filters and I am purchasing an alternative filter to match this jug. If you are interested in learning more about this filter to assess the problem (you certainly should), I'll be happy to send it to you if you send me a prepaid shipping label and shipping instructions. For the Revain website, the best rating I can give this jug is two stars out of five. Your colorful brochure is very good. Too bad that the most important part (water filter) does not meet the requirements. The blue filter that came with the jug worked well and the first replacement black filter only dropped charcoal at the very beginning but no white balls that I could see. I hope you can solve the quality problems.
