Boiling water is useful, but it doesn’t remove everything from your water.
🔥 The myth: Boiling water makes it completely clean.
💧 The reality: Boiling is effective at killing many harmful microorganisms, which is why it’s often recommended during boil-water advisories. But it does not remove most dissolved substances such as minerals, salts, many metals, or certain chemicals.
In fact, as water evaporates during boiling, some dissolved substances can actually become more concentrated in the water that remains (like PFAS).
That’s why boiling and filtration serve different purposes. Boiling is mainly used for microbial safety, while a properly selected filtration or treatment system is designed to address specific contaminants, taste, odor, sediment, hardness, or other water-quality concerns.
The best place to start? Know what’s actually in your water. Water testing can help determine which treatment or filtration option makes the most sense for your home. Annual testing is recommended for those on well water, while those on municipal water can refer their Local Municipal Water Report.
