I wanted to stop using the throw away plastic bottles due to the environmental impact they are having on the entire world so I purchased the zero water 20 cup pitcher.  It really does remove the bad odors and tastes that  come from the city public water running into my house.  I drink a lot of water, like people are suppose to, and the one filter lasts about a month.  Right now the city is doing the annual chlorine flush and the smell and taste of the water is overpowering by once it goes through the zero water filter process, no more of that taste or smell.
