The Bottle Filter uses Nano Zero with zerovalent iron technology which improves taste for a smooth finish and removes lead, heavy metals, chlorine, and particulates that meet NSF/ANSI 42, 53 & 401 standards.

Go for the Advanced Bottle Filter
I’ve been using the LARQ bottle with the Advanced Filter and overall, I’m really impressed. The biggest difference is the taste of the water, it tastes noticeably cleaner and fresher, especially when using tap water.
