Alright. Take a big, deep breath brother/sister. You will be okay, I promise. Maybe drink a nice, hot cup of tea and relax a bit.
I have been working in municipal water treatment for 10 years, and I have 15 more years of experience in water chemistry before that. I don’t know where you live, but the odds are that your tap water is perfectly safe to drink.
That said, I personally run my drinking water through a simple, carbon block filter. I use a countertop filter housing that accepts standard 2.5”x10” cartridges. Something like this:

I replace the filter cartridge once per year. It is inexpensive and effective enough to filter out chlorine and organics. I suggest that you do a blind taste test on your tea and decide for yourself.
