I'm somewhat new to home brewing, 6 extract kits to my credit now, so i'm wondering can filtering the tap water help? I'm on chlorinated water , which by it's nature is supposed to kill microbes. How does this harm the yeast during the ferment? I'm thinking about a faucet mounted filter like Pur or another brand for taking the chlorine out before my next batch. Can you more seasoned veterans give me some input on this or am I being paranoid?
