Watch out for “alkaline” or “ionizing” filters—they’re the influencer of the filter world: all hype, no substance. They won’t touch PFAS. Also, stay away from single-use plastic water bottles. Not only do they cost more per gallon than gas, but they also leach microplastics and often contain PFAS from the processing. It’s the equivalent of trying to clean your house with a dirty mop.
And that trendy “water ionizer” your friend got on Instagram? It’s basically a pricey pH adjuster. Save your money for that trip to Japan instead.
