Input:
I've had this Brita water filter for almost a year now and I really like it.  I'm a college student and when I moved to college I wasn't sure what I should do for water. Bottled water crossed my mind, and I also considered filling up one gallon jugs at a water station in town here that charges twenty five cents I believe.  For a while I bought bottled water, and then I just started drinking city water out of a pitcher in the fridge.  The city water here isn't too bad but there is a noticeable mineral taste to it.  Eventually I decided to get this filter/pitcher and I have loved it ever since.  The filter has eliminated any bad taste and I believe it even makes the water taste more smooth.  It's so nice to not have to spend money on bottled water or have to make trips to the station to constantly fill up gallon jugs.  The convenience of filling up a pitcher, which you can use to serve the water itself, and simply putting it into the fridge five feet away is a major plus here.  Another nice thing about Brita is that they offer a variety of pitchers and sizes, so if this particular one doesn't fit your liking just know that there are options out there.  If you're a "green" person, you can also take comfort in using less plastic bottles.  Fittingly, Brita uses that very environmental advantage as a selling point.  This Brita pitcher/filter is a simple, great, inexpensive way to bring good tasting water into your home.
