First off, let me say that there is nothing wrong with Chicago water. It’s one of the few things the government does right.
It does however, have a distinct chlorine taste, but I never knew because I only drink water outside of my house…
… until now.
I bought the Brita Slim Pitcher on a whim at Home Depot or Lowes or Menards.  It was on sale for $7.99 with one filter and I was on a buying jag.
It basically is what it is.  You put the filter in (soak for 15 minutes first) and just pour water in the pitcher.  The water quickly goes through the filter and Vie-Ola you have really pure tasting water.
The difference is uncanny.  So much so, that the dog and I now regularly drink water at home!
I definitely recommend this ‘lil item.

PS- Don’t forget to transfer your new water to a glass pitcher!
