Query: PUR is so much better

The charcoal bits that float around my pitcher is not acceptable, even if the manufacturer claims it is normal and safe. My pitcher has also started to leak between the top and bottom portion, so that the little bits float down to the "purified" section. How pure can my water be if tap water is passing around the filter and not through it? I replace my filter very frequently (like every 2-3 wks) since I have noticed that the bottom of my pitcher became green. How gross is that? Please save yourself this headache and buy a PUR. I've used that brand for many years and have never had any complaints. I swear water tastes better with a PUR. Their filter actually screws in the container to prevent leakage. Someone was thinking!
