Cold brew concentrate tasted like dirt for 8 straight days

I switched from my usual hot pour over to a 24 hour cold brew steep using a coarse grind from a local roaster in Austin, but every single batch came out bitter and muddy no matter the ratio. Turns out my tap water here has a ton of chlorine that wrecks the extraction, so I grabbed a cheap filtered pitcher and the next batch was night and day. Has anyone else dealt with water quality ruining their cold brew, and what filter do you swear by?

Honestly did the pitcher filter fix the bitterness or just the dirt taste?
