Water quality

Hi all, I’m moving back to SR after 5 years in Ventura County. I’ve used a brita here for years as the tap water is not drinkable here per the community. I’ve recently seen this study about how Britas don’t really do anything and while looking into options that actually filter- they’re very expensive. I’m open to looking at the other extreme- no filtering. How many of yall drink tap in SR?
