1307: Water Filters | Skeptical Sunday

Welcome to Skeptical Sunday. I'm your host, Jordan Harbinger. Today I'm here with Skeptical Sunday co-host, writer, and researcher Jessica Wynne. On the Jordan Harbinger show, we decode the stories, secrets, and skills of the world's most fascinating people and turn their wisdom into practical advice that you can use to impact your own life and those around you. Our mission is to help you become a better informed, more critical thinker, and during the week, we have long-form conversations with a variety of amazing folks, from spies to CEOs, athletes, authors, thinkers, performers.

On Sundays, though, we do Skeptical Sunday, a rotating guest co-host and I are going to break down a topic you may have never thought about and debunk common misconceptions about that topic, such as circumcision, astrology, acupuncture, the death industry, weddings, fast-fashion, hypnosis, and more. And if you're new to the show or you want to tell your friends about the show, I suggest our episode starter packs. These are collections of our favorite episodes on persuasion, negotiation, psychology, disinformation, junk science, crime and cults, and more that'll help new listeners get a taste of everything we do here on the show. Just visit jordanharbinger.com slash start or search for us in your Spotify app to get started.

Today, we're looking at what's up with water filters and purifiers. If you care what's in your water glass and you probably should, you've also probably invested in some kind of water purifier, a pitcher in your fridge, an attachment on your faucet, a whole integrated filtration system somewhere in the garage, or perhaps just cases upon cases of purified bottled water. But what do you need to know about these systems and what benefits do they offer? Are they necessary? Everybody wants pure water, but between marketing, pseudoscience, and scams, how pure is the truth?
