Distillation is basically nature’s reset button. You heat water until it vaporizes, leaving behind heavy metals, minerals, and yes, PFAS molecules, which are too large and non-volatile to travel with the steam. The vapor then cools into pure liquid—H₂O in its most stripped-down form. Studies show that home distillers can remove up to 99% of PFAS, including the pesky short-chain variants that slip through some filters.
Fun fact: astronauts on the International Space Station drink distilled water recycled from their own sweat and urine. If it’s good enough for zero-gravity coffee, it’s probably okay for your Sunday morning brew. Just know that distillation is not a magic wand; it works best when the water is pre-filtered to remove larger sediments, so you don’t gum up the machine.
The Reality Check: Trade-Offs
Here’s the real tea: distillation strips out the good stuff too—calcium, magnesium, and those trace minerals your body actually likes. You’ll get pristine water, but it might taste a little flat, like a celebrity without their glam squad. The solution? Add a pinch of mineral drops or a squeeze of lemon to bring back the zing.
Also, distillation is slow and energy-hungry—think of it as the slow-fashion of water purification. A typical countertop unit takes four hours to make a gallon, and your electric bill will notice. But if PFAS are a genuine concern in your area (check your local water report), it’s a small price for peace of mind.
