This is one of the best articles I’ve ever seen on water filtering and purification. Really well done research and organization. I’m surprised nothing from RapidPure showed up here in your review. A company out of Minnesota. Fantastic capacity, unbeatable flow rate, and 6-log virus-removal to boot. Last time I checked, their site was rapidpure.net. Did you already know about their stuff and exclude it for some reason? I think they’ve been around since at least 2012.
