Best Home Water Filters

Reading some of the stuff that is found in tap water and believe it is time to invest in a water treatment system with maybe a bladder. Don’t get me wrong, I like tap water and am grateful for it. I just want to get the best out of it. Not to sure on specifics for filtration. I use a Pure pitcher filter now which is carbon I think. Looking for a system I can use with current or next to sink faucet. Filtration along the lines of all bad stuff. Lead, chlorine, microbes, etc. I will continue looking, and thank you for help.

I’ve been using Aquasana for about 5 years and I like their products very much.
