Query: Brita's quality got worse in recent years

I have been using Brita pitchers for years. A few years ago I purchased a new one and realized that they have removed the attachment that tells you when to replace the filter. This was really a bad idea, not only it is hard to remember when to change your filter but after they changed the design I keep getting large black granules in my pitcher ach time I use it. I now need to re filter my filtered water to make sure I do not get any of these granules. I still have some filters left and I will use this pitcher until that time, after that I am switching to some other brand.
