I bought the Brita Slim Pitcher at the end of the summer for use in my dorm room. Prior to having the pitcher, I would just buy water bottles by the cases. The pitcher is a great money and environment saving alternative to buying case upon case of water bottles.
One of the best parts about this pitcher is the price. Being only about eleven dollars it is cheaper than what I first expected these pitchers to be priced at. Trust me when I say that this pitcher will soon pay for itself. I use it constantly and it has definitely saved me money when compared to buying cases of water bottles. The next great aspect of this pitcher is the taste of the water. The water tastes great, even compared to the more expensive water bottles. From my experience, I haven't really seen a need to replace the filter. I haven't noticed the quality of the water decrease, even though it would probably be better to switch the filter as suggested by the company.
Overall, I'd recommend buying this filter if you're looking for a way to both save money and help out the environment.
