This pitcher is absolutely amazing!  I had the PURR before and didn't  think it was filtering as well as it should have been for the price.  I did A LOT of research before switching and chose to go with ZeroWater.  I first got the 10 cup ready pour pitcher so that I could easily fill water bottles, but when it came the lid didn't fit right and it leaked all over.  This being said, the customer service was amazing and they told me to keep the pitcher and also refunded my money, no questions asked.  Just for this, I decided to try the larger 30 cup pitcher and am so extremely happy that I did.  I do not have to fill up the pitcher every 5 minutes, it makes my water taste amazing and I still get the same awesome company!.  #zerowatercustomerforlife
